01:23:18 | saratoga | the Sansa has no hard disk and still gets below the retail firmware unless a very fast codec like flac or mpc is used |
01:23:29 | saratoga | DMA would probably help, but its not going to close the gap |
01:23:43 | saratoga | we waste far to much power on codec decoding |
01:24:44 | saratoga | and IRAM does make a big difference for PP in codecs, since most codecs just sequentially load/store memory which is still quite slow since every single cache line must be loaded and then stored |
01:26:00 | saratoga | for instance, when doing the TDAC part of the IMDCT windowing process in WMA, I got a ~6% speed up just by putting the samples in IRAM, even though the process only accounted for < 15% of total run time |

01:55:55 | jhMikeS | they take shortcuts so they can boast about decoding speed? |

01:58:07 | preglow | i'm quite sure libmad's quality is better |
01:58:22 | preglow | but we have no good way of accessing a raw retailos decode |
01:58:31 | preglow | but yes, they can take shortcuts, like use 32 bit multiplies |

02:01:07 | * | amiconn thinks that the coldfire mp3 decoder used in the iriver is inferior to libmad |
02:01:17 | saratoga | MAD can actually cheat and do lower precision multiplies too with (supposidly) only a little loss of precision |
02:01:20 | jhMikeS | quite honestly, I think the rockbox output sounds better and I really have no bias to prefer one or the other in evaluating it. |
02:01:24 | saratoga | i don't know if we use it though |
02:01:40 | preglow | we don't |
02:01:50 | amiconn | No idea about any apple OF though (as I can't try them) |
02:01:59 | preglow | i really don't want to cut corners like that in rockbox unless we absolutely have to |
02:02:13 | saratoga | some of those tricks might make sense though, since the default mad output is good to something like 120 or 130dB, which is rather absurd for MP3 |
02:02:16 | preglow | i think the potential for sound quality we have is one of our defining features |
02:02:27 | jhMikeS | if somhow you can convert some multiplies to shift + add/sub/rsb sequences, you may very well gain speed, at least if it's 32-bit |
02:03:00 | saratoga | the trick in mad is mostly to replace 32x32=64 multiplies with 32x32=32 multiplies |

02:04:09 | Me | How far is the progress in v2s? |
02:04:14 | preglow | Me: not far at all |
02:04:27 | Me | =[ no time soon? |
02:04:28 | jhMikeS | preglow: those are difficult indeed |
02:04:41 | DerPapst | i'm sure if it gets asked a lot it's documented somewhere because people are tired of answering the same question over and over again</smart_ass> ;-) |
02:04:44 | preglow | Me: not that i know, i think some work has tasted on deciphering the firmware format, but that's that |
02:04:45 | jhMikeS | It's sort of a per-context thing |
02:04:47 | saratoga | are 32x32 multiplies a lot faster then the 32x32=64 type? |
02:05:03 | preglow | saratoga: you do shave off two-three cycles by using them |
02:05:05 | Me | :[ |
02:05:19 | saratoga | preglow: thats pretty impressive |
02:05:24 | | Quit Me (Client Quit) |
02:05:24 | saratoga | it would certainly add up |
02:05:32 | preglow | and i'd really, really we don't use them |
02:05:33 | jhMikeS | preglow: "work has tasted" <==?? :p |
02:05:43 | saratoga | anyway, I tend to think the precision of decoders is greatly overvalued |
02:05:53 | preglow | if we do, i would at least expect some very favorable comparisons |
02:06:01 | preglow | saratoga: even when doing dsp on the output? |
02:06:02 | saratoga | markun broke the WMA decoder last fall in such a way that reduces precision by about 40dB |
02:06:08 | saratoga | no one has ever noticed |
02:06:26 | preglow | saratoga: that was fixed rather quick, wasn't it? |
02:06:33 | saratoga | no i haven't bothered |
02:06:40 | jumpatrain | how exactly do you do dsp on the output ? |
02:06:59 | amiconn | saratoga: Actually multiplication speed on arm depends on how many bytes of one of the operands are pouplated. Here are the details: I tried the patch on X5 (Coldfire MCF5250, also having 128KB or IRAM). It sped up decoding of my test track from 482% realtime to 615% realtime! |
02:06:59 | amiconn | I've attached the modified patch, which also corrects the checks for PP5022 and PP5024. Those macros don't work like the CPU_* group macros. They are always defined, which would cause v1 to break on any other CPU than PP5022/PP5024. You're supposed to check CONFIG_CPU. |
02:06:59 | amiconn | Regarding IRAM distribution - I'd prefer to keep even distribution between core and codecs/plugins, like it's already done in SVN for MCF5250. While IRAM might be quite useful for codecs, it might also be quite useful in the core (e.g. for better DSP code), and there are often also some target specific tasks in the core which profit from extra IRAM. |
02:07:02 | saratoga | i wanted to look at other ways to attempt his optimization before i reverted it |
02:07:09 | jhMikeS | "exactly"? I think the source is needed for that. |
02:07:12 | amiconn | Bah, what was that! :( |
02:07:23 | preglow | amiconn: looks like a paste to me :) |
02:07:27 | amiconn | yeah |
02:07:42 | amiconn | But not the one I wanted to do |
02:07:52 | saratoga | amiconn: since core uses only a very tiny percentage of total CPU cycles, I'm curious what the use of more IRAM would be? |
02:08:03 | | Quit kennyj (Remote closed the connection) |
02:09:05 | saratoga | i mean, buschel and I's patches, each save more CPU cycles the entire core uses for typical decode (ignoring resampling and EQ I suppose)\ |
02:09:19 | amiconn | I already mentioned the main purpose (DSP). |
02:09:34 | preglow | i don't know how wise it is to keep reserving iram we might never use, though |
02:09:36 | amiconn | There are target specific things like framebuffer |
02:09:54 | saratoga | do any of our targets with 128k need that though? |
02:10:16 | amiconn | Even the 16K extra for codecs are currently unused on MCF5250 |
02:10:31 | amiconn | I only used them once for an APE test |
02:11:03 | saratoga | for PP at least, I don't believe we use even the 48k we've reserved now, so I don't see much point in adding more |
02:11:19 | saratoga | and for coldfire, it would be nice to use the same split, so that optimizations apply to the X5 as well |
02:11:31 | amiconn | So I'd keep even distribution for now, and if it later turns out that it's better used for codecs (or for the core), we can change that |
02:11:35 | jumpatrain | i can hear noise when im listening to silence on this sansa |
02:11:38 | jumpatrain | is that normal ? |
02:11:56 | saratoga | amiconn: I've got a good use for the extra 32KB right now |
02:12:00 | saratoga | the WMA codec . . . |
02:12:15 | saratoga | i can put the output buffer in IRAM and speed up both decoding and DSP operations |
02:12:25 | kkurbjun | Is a 12% power savings worth a little extra LCD startup time after it turns off? |
02:12:49 | kkurbjun | I mean how much would that bug people on the gigabeat F do you think? |
02:12:53 | preglow | how much? |
02:13:12 | saratoga | presumably the same trick would be applicable to AAC too, since it uses nearly the same windowing process |
02:13:14 | scorche|sh | 12% is pretty big.. |
02:13:18 | pixelma | jumpatrain: yes, unfortunately the Sansas are a bit noise (a bit depends on your exact player) |
02:13:26 | pixelma | s/noise/noisy |
02:13:36 | kkurbjun | it's a split second after the backlight fades in.. you see a white screen for a brief time and then the normal screen comes up |
02:13:38 | preglow | saratoga: aac would love iram |
02:13:54 | jumpatrain | pixelma sansa e280. |
02:13:55 | jumpatrain | :( |
02:13:57 | saratoga | i mean pretty much any pure IMDCT codec should be able to very profitablely use more then 64 kbps of IRAM (as in use it 4 or 5 times per sample instead of DRAM) |
02:14:14 | amiconn | saratoga: If you reduce core iram to 48KB, the M5 will be quite tight (X5 has a bit more room) |
02:14:23 | saratoga | because of it's frame buffer? |
02:14:56 | saratoga | for a pure IMDCT codec, you optimally need 48KB of IRAM just for the IMDCT |
02:15:07 | saratoga | and thats not counting any of the FFT constants or windowing or any of that |
02:15:21 | saratoga | 48KB just for the sample data, since each pass of the IMDCT processes 48KB worth of data |
02:15:41 | kkurbjun | preglow, scorche, I tried to eliminate the startup time, but it seems to be a limitation of the on glass LCD controller, not the one in the SOC. I could commit it first and see how people take to it |
02:15:57 | preglow | kkurbjun: yeah, but how much extra start time? |
02:16:02 | scorche|sh | kkurbjun: if it is a split second for 12%..... |
02:16:08 | saratoga | with 64 KB, you can start to put things like FFT constants, Windowing constants, and trig tables in IRAM too |
02:16:09 | preglow | split second can be anything :> |
02:16:15 | kkurbjun | it's probably on the order of 15 ms |
02:16:21 | kkurbjun | about |
02:16:21 | saratoga | at 80KB you can fit virtually everything and avoid DRAM pain altogether |
02:16:24 | preglow | *shrug* |
02:16:27 | preglow | see what people thinj |

02:17:55 | amiconn | All other cf targets are lower than that though |
02:18:13 | pixelma | jumpatrain: I actually meant small differences in the production, so your unit. Some people hear something, some not, probably has to do with earphones and ears too... |
02:18:16 | kkurbjun | ok, I'll commit it and see if anyone really hates it :-D |
02:18:19 | saratoga | amiconn: how much would you save by putting the buffer in DRAM like on color targets? |
02:18:26 | amiconn | I'm not entirely sure, but I think this is because both the main and remote framebuffers are in iram |
02:19:02 | amiconn | While it's the same situation as on H1x0, the M5's remote framebuffer is larger than the H10's |

02:20:44 | jhMikeS | hmmm, HP is primary, then it's mixer |
02:21:59 | saratoga | i think its radix 2 ? |
02:22:37 | preglow | anything else would be foolish |
02:22:49 | preglow | wma only uses blocks that are power of two, afaik |
02:22:55 | saratoga | well theres radix 4 and split radix |
02:23:06 | saratoga | you can in theory do quite a bit better then radix 2 |
02:23:37 | preglow | split radix is usually the best on ordinary cpus |
02:23:48 | preglow | well, whatever this fft is, it surely doesn't look optimal |

08:11:49 | * | amiconn thinks that patch should probably be committed |
08:12:37 | Buschel | saratoga/preglow: regarding your discussion about 32x32=32 multiplies for mp3-decoder. i am doing the same in the mpc-decoder right now. a lot of tweaking via pre-/postscaling the coefficients and samples must be done −− prescaling should also be done with rounding, not via simple truncation. |
08:12:48 | amiconn | It will help ipod Mini G2, Nano, Video; the Sansas, and iaudio M5 and X5 |
08:13:25 | Buschel | saratoga/preglow: of course it adds additional noise, but far below masking threshold from my tests last year. |

08:16:46 | Buschel | amiconn: we can compare the gain of dsp in iram via codecs with more iram. the solution which is more efficient overall wins :) |
08:16:52 | amiconn | Some non-audio related things too, probably |

08:33:08 | Llorean | I seem to recall some discussion about the "IPOD version: 0xFFFFFFFF" being wrong, but I think all 5.5Gs still do that anyway? |
08:33:15 | Llorean | And probably unrelated. |
08:33:29 | linuxstb | That's unimportant (and fixed in SVN for a long time). |
08:33:47 | linuxstb | That value isn't actually used for anything for the Video builds. |
08:34:22 | Llorean | =/ |
08:34:48 | Llorean | Can we rule out firmware 1.3 (is anyone using it?) |
08:35:49 | linuxstb | I'm sure they are - I remember quite a few people complaining (wrongly) about Rockbox not working when they upgraded to 1.3, but that was simply because the bootloader was erased. A re-install of the bootloader fixed it. |
08:35:58 | Llorean | Okay. |

09:08:16 | pondlife | I'd be more concerned if file systems are being corrupted once Rockbox USB is in use. |
09:10:02 | Llorean | I've gotten a few corrupted files on my Gigabeast, but I *think* that was a bad cable. |
09:10:10 | Llorean | (in regards to Rockbox USB) |
09:10:31 | pondlife | I mean, we don't write that much at the moment (database building mainly)... |
09:10:47 | Llorean | Constant .cfg files updating |
09:10:53 | pondlife | Ah, true. |
09:10:56 | Llorean | Which, consequently, is a file we get reports of corruption in quite often. |
09:11:12 | linuxstb_ | Isn't the "recommended bootloader" simply the latest release on download.rockbox.,org ? |
09:11:19 | Llorean | linuxstb_: Yes. |
09:12:34 | pondlife | That's not very visible from the website though. |
09:12:54 | pondlife | Does RBUtil use http://download.rockbox.org/ for bootloaders? |
09:13:07 | Llorean | I believe it's supposed to. |
09:13:27 | Llorean | But a table showing current bootloader version, and giving instructions for determining which one you have, might be nice. |
09:13:33 | Llorean | Or "current" and "minimum" |
09:15:02 | * | GodEater maintains he's never experienced any sort of file corruption on any of his targets. And I use the last.fm stuff too - so there's constant disk writing going on for me. |
09:15:41 | Llorean | GodEater: Do you have an 5.5G or a Sansa? |
09:15:46 | GodEater | both |
09:16:00 | GodEater | the 80GB, and a c240 |
09:16:10 | GodEater | and the c240 has an 8GB card in it too |
09:16:29 | GodEater | haven't used rockbox usb with the sansa yet though |
09:16:43 | Llorean | Not a good idea to yet, I believe. |

09:16:58 | Llorean | IIUC with the sansa there *is* a chance of FS corruption with Rockbox USB. |

09:17:32 | Llorean | Well, I guess no sense worrying until some of us start seeing these corruption problems. |
09:18:01 | Llorean | But there's just a lot of reports on the forums. I wish there was a way to transmit to users that it's probably not caused by Rockbox without sounding like we're just passing the blame. |
09:18:17 | amiconn | pondlife: database (if used), config.cfg, nvram.bin (except on real nvram targets), .playlist_control |
09:18:38 | pondlife | I thought gevaerts had seen Sansa SD corruptions regularly. |
09:18:40 | Llorean | And I don't think we've seen any signs of nvram corruption or loss of .playlist control. |
09:18:47 | Llorean | pondlife: With use of USB. |
09:19:04 | pondlife | Yes, but only on the SD card (IIRC). |
09:19:30 | Llorean | pondlife: I think it's the main filesystem too, it also uses the SD driver, so you may have seen mention of it being a problem with SD? |
09:19:38 | pondlife | Ah, ok. |
09:19:38 | GodEater | Llorean: I'm positive that the problem is from people who don't get the idea that they have to do the "safely unplug" hardware thing |
09:19:56 | amiconn | GodEater: On windows you don't have to... |
09:20:02 | Llorean | GodEater: Especially since both devices tend to use managers that handle the ejection for you. |

09:20:48 | pondlife | My H300 always takes at least 2 attempts to disconnect/eject... |
09:20:52 | amiconn | At least as long as you don't enable write caching for removable storage (it's *disabled* by default, with the exception of the archos USB1.1 hdd targets which need their own driver) |
09:21:31 | GodEater | amiconn: I'm with pondlife on this one, my devices complain a lot about unsuccessful attempts to unmount them, which makes me believe there's still stuff being written to them |

09:22:44 | pondlife | GodEater: Windows agrees with amiconn - "This setting disables write caching on the disk and in Windows, so you can disconnect this device without using the Safe Removal icon." |
09:22:45 | pixelma | pondlife: I'm seeing this on my M5 too and noticed just recently that after the first remove the disk stops spinning and second remove is successful |

09:23:06 | amiconn | GodEater: The unsuccessful attempts are practically *always* due to explorer still holding a lock on the device |
09:23:07 | Llorean | GodEater, pondlife: With the H100/H300 it just seems to be a quirk of them. I can not write anything at all, and it'll take two attempts to eject my H100 |
09:23:10 | * | linuxstb wonders if there are any background tasks that could be running and using the disk |
09:23:27 | pondlife | That's exactly what I see. I don't think it used to be this picky, but it may be a service pack weirdness. |
09:23:29 | * | GodEater blames the recycle bin code |
09:23:29 | amiconn | This has nothing to do with unwritten data |

09:28:22 | amiconn | pondlife: Then you have write caching enabled for some reason. Is this on windows xp? |
09:28:36 | pondlife | Yes, and caching is disabled (apparently) |
09:29:13 | pondlife | "Optimize for quick removal" is selected, not "Optimize for performance". |
09:29:28 | amiconn | SO it should be disabled |
09:29:45 | * | amiconn wonders what special background processes pondlife might have running |
09:29:46 | pondlife | Indeed, but something is still delaying writes. |
09:30:02 | pondlife | Nothing much, no indexing or similar |
09:30:37 | amiconn | I know this message, but I only saw it when write caching was enabled, or when pulling the cable before writing finished |
09:31:03 | amiconn | (or when a bug on the device side, like in the rockbox usb stack, prevented writing from finishing properly) |
09:31:23 | pondlife | How do you know when writing finishes, listen for spindown? |
09:31:58 | pondlife | I might as well enable write caching if I'm going to "safe remove" anyway... |

11:27:19 | BuXY95 | i have question |
11:27:31 | BuXY95 | tried to search the site before, but no luck |
11:27:39 | LinusN | shoot |
11:28:26 | BuXY95 | iriver h120. i'd like to record with a stereo external microphone. using line-in, i can't boost the gain to get acceptable volume |
11:28:58 | LinusN | then you will need an external amplifier |
11:28:59 | petur | you mean 48dB is not enough? |
11:29:17 | BuXY95 | i get about -40dB when i shout at the mike! |
11:29:25 | petur | impossible |
11:29:36 | petur | maybe wrong mike type? |
11:29:46 | BuXY95 | i'm using sony ecm-ms907 |
11:30:23 | BuXY95 | and the original firmware has an option for external mic, boosting the signal way up |
11:30:35 | petur | did you select line-in? |
11:30:42 | BuXY95 | in rb, yes |
11:31:00 | petur | and gain set to 48dB? |
11:31:27 | BuXY95 | well, my max value is 12.0dB (sometimes 12.5 dB) |
11:31:38 | petur | got AGC enabled? |
11:32:01 | BuXY95 | err, yeah... btw, the recording screen has a bug. |
11:32:51 | petur | no, that is intentional ;) |
11:33:09 | petur | disable AGC first |
11:33:50 | BuXY95 | i have safety agc, and the recording screen has a hidden feature: going down below agc type, the line changes to "agc max gain" :) |
11:34:16 | petur | yes, that is intentional to save space on displays with less lines |
11:34:22 | BuXY95 | and yes, letting agc max gain to 48 dB, i can boost the gain to 48 dB, and that is enough for the mike |
11:34:35 | petur | yes |
11:34:52 | petur | but anything above 20dB will be noisy |
11:35:11 | BuXY95 | well, fine, but then at least the lower half of the screen should be scrolling, right? |
11:35:12 | petur | so depending on what you want to do, an external amp might be better |
11:35:32 | petur | that is something we're working on |

11:36:45 | petur | there are some patches for that but they are a bit old |

11:40:50 | petur | and anyway, you should have at least some gigabytes free becuase if the disk is seriously fragmented you'll get buffer overruns and thus gaps in the recording |

13:51:39 | Nate263 | I just tried to install Rockbox on my Iriver 5 gb H10 and it didn't work. The error message System Files Missing came up on the iriver. I connected it to iriver plus and "initalized" it deleting what few files I had on there and supposedly reinstalling the firmware but I still get the System Files Missing error |

13:51:43 | BuXY95 | err: bug (iriver h120): recording screen - context menu - pressing STOP wants to create a bookmark |
13:52:24 | Nate263 | BuXy95, I was clever and cut and pasted the long sentence so that I could write that without losing what I wrote before |
13:52:45 | BuXY95 | nate263 good boy :))) |

14:19:35 | B4gder | yes, several of us |
14:20:17 | BdN3504 | or is it constrained only to people really working on the project? |
14:20:23 | B4gder | I think we basically welcome anyone as long as we can fit all in the place |
14:20:55 | BdN3504 | cool, i got several more questions |
14:20:58 | B4gder | but I also think it isn't very useful unless you're at least interested in it from a development standpoint as well |
14:21:17 | BdN3504 | will there be an entry fee? |
14:21:48 | B4gder | we're just a team of guys gathering, there's nothing really formal so there's no fees etc |
14:22:13 | BdN3504 | ok, then something else: i live in berlin and have space to offer |

15:37:10 | PaulJam | maybe a dead battery? have you tried it with the charger connected? |

18:04:56 | jhMikeS | it's usually nescessary to wait about a frame so an image has been written first |

20:06:48 | mcuelenaere | amiconn: each of those targets aren't really that different to the ZVM30GB |
20:07:10 | amiconn | Well, they *are* different targets in configure |
20:07:20 | mcuelenaere | yes, that's true |
20:07:21 | amiconn | Many targets are very similar to each other |
20:07:36 | mcuelenaere | I thought it would be a bit overkill to have different config-xx.h |
20:07:37 | amiconn | E.g archos fm recorder and recorder v2; iaudio X5 and M5 |
20:08:17 | mcuelenaere | do the ipod 5.5G 32MB and 64MB have different config? |
20:08:20 | amiconn | In fact I won't consider two targets *very* similar if they even have different lcd resolution and/or depth |
20:08:52 | amiconn | No, since that's only a ram size difference |
20:09:16 | mcuelenaere | ok, maybe the Zen Vision could be split up |
20:09:28 | mcuelenaere | but the ZVM30GB and 60GB only differences is an other USB chip |
20:09:41 | mcuelenaere | so I suppose those don't need a separate config, |
20:09:41 | amiconn | ...and those 2 use the same target selection in configure |
20:09:42 | mcuelenaere | ? |
20:10:30 | preglow | if there's even a slight change in key configurations, screen size, etc, they should have different configure options, imo |

20:10:37 | gevaerts | The difference with the 32MB and the 64MB ipods is that the 32MB build actually works perfectly on any ipod video |
20:11:00 | amiconn | I think we should keep the rule that if there are 2 target ids in configure, each of those should also get its own config-*.h |
20:11:08 | mcuelenaere | the 30GB could work perfectly on the 60GB if it weren't for the firmware format signature.. |
20:11:38 | amiconn | mcuelenaere: Same reason why the archos fm recorder and recorder v2 builds are different |
20:11:49 | mcuelenaere | amiconn: so the for the 3 targets, there need to be 3 config-*.h ? |
20:12:08 | amiconn | The rockbox code, and even the scrambling, are binary *identical*. The only difference is the model id in the header |
20:12:30 | amiconn | ...preventing an fmrecorder ajbrec.ajz from being loaded on a v2 and vice versa |

20:12:43 | mcuelenaere | ok, then I'll change the files according to Rockbox philosophy :) |
20:12:47 | amiconn | I think so, yes |
20:13:47 | amiconn | It's not that each target is *required* to have its own target id, e.g. the iPod G1 and G2 share a build, handling slight hardware differences at runtime |
20:14:53 | amiconn | But then the build works out of the box on both, without any file name differences. The main reason for doing this is that ipodpatcher can't distinguish 1st and 2nd gen ipods, because the OF is also shared |
20:15:43 | preglow | let's make a universal arm build that works on all arm based targets! :) |
20:15:44 | mcuelenaere | the problem is, it requires several target id as the header file of the firmware needs to be different (ie the 60gb won't accept a 30gb fw) |
20:16:29 | amiconn | Yes, and hence the config-*.h files should also be different, at least if we decide to stay with the current concept |
20:17:30 | amiconn | We could change the concept, but there's always the problem with ifdefing where to draw the line |
20:17:40 | amiconn | preglow: We're not ipl... |
20:22:38 | jhMikeS | that meg-fx controller takes a rather long time before an image is available (~200ms) |

21:56:07 | | Part czajkowski |
21:56:19 | preglow | but with different command sets |
21:56:27 | amiconn | In SPI mode it's optional, and on Ondio we just don't care. (the crc bytes still need to be present though) |
21:56:39 | preglow | don't know about spi mode, i don't think we'll need it |
21:57:01 | amiconn | SPI mode is for really simple hookups without dedicated SD/MMC controller |
21:57:12 | preglow | very weird, the data i get from the card seems to be correct, it just claims to never have powered up, but controller claims crc failed |
21:57:39 | bertrik | probably stating the obvious, but SPI mode does not require CRC except for two commands |
21:58:06 | jhMikeS | is there an auto kick on the build server now? |
21:58:34 | amiconn | Ah, so it's two for SD. For MMC it's just one - the first one, which then disables crc support |
21:58:58 | amiconn | And since that first command is constant, the crc is also constant, hence just precalculated |

21:59:29 | preglow | but i doubt i'll get any mmc cards, so i'm just ignoring it |
21:59:55 | amiconn | bertrik: Maybe doing the same, but MMC actually has two CRCs, CRC-7 for commands and parameters and CRC-16 for data |
22:00 |
22:00:04 | preglow | amiconn: same for sd, afaik |
22:00:28 | preglow | hmm |
22:01:07 | jhMikeS | that was a build auto kick, eh? (restarted) |
22:01:40 | amiconn | jhMikeS: The build system learned that trick a few weeks ago iirc |
22:02:12 | amiconn | But sometimes it doesn't work, afaik that happens if svn is locked for some reason |
22:02:13 | jhMikeS | I thought I saw it do it once sometime back but wasn't sure if it was just manual |
22:03:22 | jhMikeS | I guess it needs to run "svn cleanup" first ? |
22:03:34 | bertrik | AFAIK, the data CRC is never required in SPI mode sd cards. The command CRC is required only for CMD0 (go idle state) and CMD8 (send if cond). |
22:11:01 | pixelma | <BigBambi> I do agree actually about the use of supported, but it is very easy to slip back into using it <- that's why I started reminding people of it and what do I get? :( |
22:11:17 | BigBambi | pixelma: jokes :) |
22:11:21 | Buschel | the build table is a bit misleading... my change did nothing with lcd-stuff ;-) |

22:17:25 | * | gevaerts wonders if the build scripts in svn are up to date |
22:18:35 | Bagder | the buildmaster script in www/tools is basically the same one running now |

22:18:55 | pixelma | BigBambi: it isn't about winning, I'd hope though... |
22:19:05 | amiconn | preglow: As fine resolution as possible without needing extreme measures. PP is currently the lowest-resolution one |

22:22:49 | Bagder | then I'll put that on hold a while more |
22:23:08 | mcuelenaere | what are the biggest requirements for getting it running? |
22:23:08 | shotofadds | four 16 bit, two 20 bit, one 32 bit... |
22:23:28 | amiconn | We use 3 (on Player) resp. 2 (all other archoses). One more when debugging MAS data transfer |
22:23:33 | Bagder | mcuelenaere: there's usually not a lot once the main build builds |
22:24:26 | pixelma | BigBambi: ok. It's just if you say 'because of (me)' it feels a bit like when our forum friend z. said "follow the rules because the moderators don't like it". :P |
22:24:33 | preglow | shotofadds: problem with using the other timers as usec timers will of course be that they won't have enough bits to do any decent timeout intervals :/ |

22:25:14 | amiconn | preglow: Are there prescalers? |
22:25:19 | preglow | amiconn: yep |
22:26:02 | preglow | at least i think so... |
22:26:10 | shotofadds | all timers are based on a single source (currently 2MHz), which can then be divided and pre-scaled individually by each timer |
22:26:19 | amiconn | Well, then you might not need to reserve the 32 bit timer as the user timer |
22:26:26 | Bagder | ok, now all we need is a commit and there should be 3 creative builds |
22:26:41 | jhMikeS | Bagder: done :) |

22:27:06 | Bagder | I still can't browse the site though |
22:27:10 | pixelma | BigBambi: sorry, my last sentence doesn't make sense but I see you understood. Anyways I take that as joke now, case closed. :) |
22:27:24 | Buschel | did anyone make proflings of synth.c for libmad? would be intersting to compare the results to synth_filter.c in mpc. the filterbank is the same |
22:27:27 | preglow | amiconn: hrm, prescaler varies from 2 to 2^5 for each timer individually |
22:27:34 | amiconn | The SH1 timers are all 16 bit only. If you specify a longer timeout than e.g. 65,536/12,000,000 sec on Ondio, it will start using the prescaler, gradually lowering absolute resolution |
22:27:41 | BigBambi | pixelma: cool :) |
22:27:44 | preglow | that would be enough for all but the most long intervals |
22:27:48 | shotofadds | preglow: that's the source divider. there's also a separate prescaler (iirc) |
22:27:54 | preglow | shotofadds: can't say i find it |
22:27:58 | mcuelenaere | gevaerts: what's to wonder about it? :) |
22:28:07 | gevaerts | Do they exist ? |
22:28:34 | preglow | shotofadds: the 32 bit one has an extra prescaler, but doesn't look like the others do |
22:28:38 | mcuelenaere | gevaerts: yes, but they aren't really needed |
22:29:06 | mcuelenaere | do UI simulators require a button for the hold button? |
22:30:06 | amiconn | The prescaler on SH1 is limited to 1/2/4/8, so the max. timer interval is pretty limited |
22:30:35 | shotofadds | preglow: hmmm, you're right. there's no extra prescale except on the 32 bit timer. seems I'm losing my mind... |
22:31:17 | preglow | jmworx: ping? |
22:31:59 | amiconn | That means that even the 20 bit timer on TCC will allow longer timer intervals than the SH1 timers |
22:32:15 | amiconn | ...without needing a prescaler |
22:32:33 | mcuelenaere | where are the images for the simulators get from? Can I take a picture from creative.com and make it fit in or is this a copyright violation? |
22:32:54 | amiconn | mcuelenaere: They're usually scans of the device |
22:33:25 | mcuelenaere | amiconn: and can I take for example this picture? http://images.europe.creative.com/iss/images/artwork/A6_RGB/Zen_VisionM_Black_a.jpg |
22:33:45 | shotofadds | It looks like the timer source clock can be divided by 2/4/8/16/32 or 1024/4096. |
