| 02:05:40 | the_Kyle | I read in the manual about some plugins that play sounds. Is Rockbox capable of running a self-voicing application or game that uses sound files to play speech, either using the existing voice system or using its own files of a supported type like regular speex, mp3, Ogg Vorbis, etc.? |
| 02:08:06 | krazykit | there is work done on an espeak plugin, but it cannot be included due to licensing issues: http://www.rockbox.org/tracker/7660 |
| 02:08:28 | Torne | plugins can play sounds, yes |
| 02:08:46 | Torne | not using the voice system, but the playback system works |

| 02:13:50 | | Quit BHSPitMonkey (Remote host closed the connection) |
| 02:15:31 | the_Kyle | Sucks that eSpeak is GPLv3 and Rockbox is GPLv2. The fact that the plugins can play sounds, however, opens up a wide range of possibilities for audio games, talking calculators, etc. |
| 02:16:51 | tmzt | there's flite |
| 02:16:54 | the_Kyle | SVox Pico is probably portable enough to run as well, but I don't think the Apache license is fully compatible with GPLv2 either. |
| 02:17:49 | the_Kyle | I didn't even think of Flite. Seems it has some really nice voices these days. |
| 02:20:29 | the_Kyle | I know that Rockbox seems to have accessibility to blind users in mind, but is the blind Rockbox community active in development and suggestions for better usability? |
| 02:22:02 | the_Kyle | I'm just hoping I'm not the first in a long time to take more than a passing interest in this aspect of Rockbox.. |

| 02:26:43 | [Saint] | flite and espeak were looked at for a GSoC project, and both ended up being a whole barrel full of laughs if I remember. |
| 02:28:25 | [Saint] | There's a wiki page for TTS in core iirc, but I don't think it got very far at all... |
| 02:28:35 | the_Kyle | Well, I know that at one time, Flite sounded very bad, but it seems that new voices have been developed that sound much better now. As for how portable the code is, I'm really not sure. That may be where the issue lies, although Flite advertises itself as being specially designed for embeded systems. |

| 06:32:44 | mordocai | Hello, does anyone know if anyone is working on http://www.rockbox.org/tracker/task/11655? It is really a very annoying issue. I'd be willing to help with any debug I can do from my end. (I'm the last poster... the multiple posts are because I forgot something and then accidently hit refresh the next day as well...) |
| 06:51:00 | [Saint] | Hmmmm...why is it that My Nano2Gs all mount as "Apple iPod Nano2G" but my 1st Gen Nano mounts as "SST55LD0 19K-45-C-MWE USB Device"? |
| 06:52:56 | [Saint] | I've also noticed that 'Debug (Keep Out!) - View Disk Info' is kinda busted on the Nano2G |
| 06:53:20 | [Saint] | it just seems to repeat the same info 4 or 5 times. |
| 06:53:47 | JdGordon| | my "Panic: no font" error beats both of them by a country mile! |
| 06:54:16 | [Saint] | ..about 4.2 times actually. |

| 09:58:27 | [Saint] | iPod Nano 1st Gen: rockbox-info.txt == "CPU: arm, Manufacturer: ipod", I would personally have as "CPU: PP5022, Manufacturer: ARM" |
| 10:00 |
| 10:01:01 | pixelma | huh? |
| 10:01:26 | [Saint] | just saying "arm" for CPU is a bit vague, and I'm sure noone needs a txt file to tell them the manufacturer of their iPod (which if it's used in the way it is currently, should read as Apple instead of ipod btw...) |
| 10:02:48 | [Saint] | I'm not sure what the "huh?" is for...in rockbox-info.txt the two fields of CPU and Manufacturer seem to be filled incorrectly to me. |
| 10:03:29 | [Saint] | it reads as: "CPU: arm, Manufacturer: ipod" when I think it would make more sense if it were to read "CPU: PP5022, Manufacturer: ARM" |
| 10:03:59 | [Saint] | or, at the least change "Manufacturer" to Apple instead of iPod |
| 10:07:50 | [Saint] | yes...it's definitely been used differently by different ports. Nano 1 and 2 G are a good example |
| 10:08:14 | [Saint] | Nano1G states (as above), and Nano 2 G reads: "CPU: arm, Manufacturer: s5l8700" |
| 10:08:35 | amiconn | What rockbox-info.txt tells here is the target tree structure |
| 10:08:55 | *** | Saving seen data "./dancer.seen" |
| 10:09:18 | amiconn | Since the old ipods were added before the slightly different structure for arm was decided on, CPU = arm and manufacturer = ipod is correct |
| 10:09:22 | [Saint] | I'm sure it could be jiggled to give correct info though, no? |
| 10:09:31 | amiconn | (until someone restructures all the pp targets) |
| 10:09:41 | amiconn | It could, but it shouldn't |
| 10:10:32 | [Saint] | having the CPU type as the "manufacturer" for the Nano2G seems all types of weird to me. |
| 10:10:53 | [Saint] | I'm wondering what other targets have crazy info like that as well now. |
| 10:11:02 | amiconn | Target tree is structured architecture/manufacturer/model |
| 10:11:31 | amiconn | Architecture is 'arm' for all ipods (obviously). |
| 10:12:10 | amiconn | Manufacturer was originally named 'ipod' and not 'apple' because ipod is actually a family of models. |
| 10:15:33 | amiconn | Later it was decided that the manufacturer part should be used for the SoC in case of arm, because there are so many |
| 10:15:33 | [Saint] | I understand what you're saying...I just don't think it works as well now as it once did. To me, when I think of the manufacturer of iPod, Apple springs to mind immediately...but iPod isn't "wrong" per se. I do think that using the CPU type as manufacturer is just cray though. |
| 10:15:33 | amiconn | So the correct identification for Nano G1 would be arm/pp5022/ipod-nano1g by the new standard, but switching to that means reordering *all* PP targets |
| 10:15:33 | [Saint] | s/cray/crazy/ |
| 10:15:33 | amiconn | It does work well, just the fields in rockbox-info.txt should perhaps be named slightly different |
| 10:15:33 | DBUG | Enqueued KICK amiconn |
| 10:15:33 | amiconn | CPU -> architecture, manufacturer -> family |
| 10:15:33 | [Saint] | yes, that was going to be my second suggestion if reordering the info was too daunting. |
| 10:15:56 | [Saint] | making the headings in rockbox-info.txt more appropriately worded. |
| 10:17:54 | [Saint] | the former suggestion will be a lot more work (but, IMO the "right" thing to do), re-wording the headings in rockbox-info.txt will be a *lot* less work however. |
| 10:18:28 | [Saint] | I'm not even sure it's too important, just every now and then I notice something that I think is kinda weird and try to put it right if I can. |

| 13:26:14 | amee2k | i click Restore. it sits there with a progress bar "contacting ipod software update server", then says it failed to connect and i should check my network settings |

| 13:46:31 | amee2k | i only have the USB cable. it didn't come with a wall charger |
| 13:49:51 | [Saint] | oh....shit, with older iPods you need the wall charger (or possibly firewire also...) cable to complete the update |
| 13:50:40 | amee2k | i have a lab PSU here... i'll rig a charger |
| 13:51:05 | amee2k | they need some pullup and pulldown resistors on the data lines so they know its a charger |
| 13:51:18 | [Saint] | be carefull ;) |
| 13:51:30 | amee2k | i'm googling for the resistor configuration but not much info... |
| 13:51:42 | [Saint] | though, pinouts for the chargers are everywhere on the net if you look hard enough. |
| 13:51:47 | wodz | I just used scotch tape to isolate D+/D- lines and plugged this to PC |
| 13:52:16 | [Saint] | hmmmm, that's a cool idea wodz |
| 13:52:16 | amee2k | are you sure it works with ipods too? |
| 13:52:44 | amee2k | there was an article about this somewhere... apple has a way of proprietroizing USB charging :/ |
| 13:52:45 | wodz | sure - I have ipod mini CF modded :-) |
| 13:52:51 | [Saint] | I believe wodz is referring to an iPod |
| 13:53:25 | amee2k | oh, cool :) |
| 13:53:31 | Torne | amee2k: there's an exciting variety of resistor network configs suggested by various places |
| 13:53:57 | Torne | apple have *not* proprietized USB charging; their USB chargers simply predate there being a standard spec |
| 13:54:03 | Torne | you can try just shorting D+ and D- |
| 13:54:16 | Torne | some ipods certainly recognise that, i'm not sure if all do, thoguh |
| 13:54:26 | amee2k | Torne: once you have a reference to justify every configuration, its just like no reference at all ;) |
| 13:54:35 | Torne | hm? |
| 13:54:46 | amee2k | i'll try wods suggestion and just put it on 5V |
| 13:55:06 | * | gevaerts seems to remember that ipods indeed aren't very picky about D+/D- for charger detection for firmware upgrades |
| 13:55:15 | Torne | perhaps not |
| 13:56:07 | Torne | anyway. it's the entire rest of the world until recently that was doing USB charging in a broken way, apple were doing much better ;) |

| 13:56:33 | Torne | positive charger detection is a feature, not a bug |
| 13:57:21 | amee2k | i thought the rest were just waiting until they see 5V on the power pins. then start charging |
| 13:57:25 | amee2k | whats broken about that? |
| 13:57:38 | [Saint] | though, some people/projects make it seem like a form of black arts |
| 13:57:41 | [Saint] | or voodoo |
| 13:57:48 | Torne | amee2k: the USB spec explicitly forbids you from doing that |
| 13:58:07 | Torne | doing so can cause physical damage to some devices :) |
| 13:58:21 | amee2k | the wall wart chargers don't care |
| 13:58:42 | Torne | You are not allowed to draw more than 100mA of current from USB +5V until you have been enumerated and configured to a higher power profile by an active host |
| 13:58:55 | amee2k | and a host that can be damaged permanently by overcurrent is arguably broken too |
| 13:59:05 | Torne | And you aren't even allowed to draw that 100mA for very long, really; you should give up waiting after a while and go into suspend, which requires <50uA or something similar |
| 13:59:40 | Torne | and yes, hosts should have overcurrent protection |
| 13:59:43 | Torne | but that doesn't mean they do :) |
| 14:00 |
| 14:00:16 | Torne | It wasn't until comparitively recently that the USB-IF put out a spec for how to deal with charging and how to handle dumb AC adapters |
| 14:00:34 | Torne | Apple invented their own scheme years before to solve the same problem |
| 14:01:01 | Torne | current apple chargers manage to implement both schemes using a cunning resistor network :) |
| 14:01:19 | Torne | and current apple devices use the standard USB charging scheme |
| 14:01:23 | [Saint] | yeah, it is pretty cool they way they do it. |
| 14:01:37 | Torne | so, yeah. the rest of the world was wrong and apple was right. :) |

| 14:22:54 | gevaerts | AlexP: isee36975 |

| 14:24:43 | Mataniko | silly question but couldn't really find a yes or no answer, does rockbox on ipod photo support playback through docks? |
| 14:24:45 | CIA-7 | New commit by kugel (r28757): Correct two problems slipped in with r28753. Thanks Teru for spotting. |
| 14:24:58 | Torne | Mataniko: playback almost certainly; controls work on many docks but not all |
| 14:25:07 | Torne | there is no yes or no answer |
| 14:25:12 | Mataniko | thats good news, worth a try |
| 14:25:20 | Torne | Apple's accessory protocols are not documented, but we understand some of them and do our best |
| 14:25:31 | Mataniko | car is reporting "not authorized" on an older ipod |
| 14:25:39 | Mataniko | so can't lose |
| 14:26:06 | Torne | if it doesn't work with the original firmware then it's probably expecting one of the later accessory protocols which we don't understand either |
| 14:27:09 | CIA-7 | r28757 build result: All green |
| 14:27:10 | Torne | if the car stereo supports non-ipod players then there is a way to make the ipod appear to not be an ipod, though, which may make it work :) |

| 14:27:46 | | Join kugel [0] (~kugel@rockbox/developer/kugel) |
| 14:28:13 | Torne | then the stereo will just see it as a generic storage device |

| 14:28:34 | Mataniko | thats a good idea |
| 14:28:45 | Mataniko | it def plays from generic storage |
| 14:28:59 | Torne | ok. |
| 14:29:04 | Torne | you will need to make your own build of rockbox |
| 14:29:13 | * | Torne was going to add a feature to let users set the USB IDs but hasn't done it yet. |
| 14:29:20 | Mataniko | does it compile with msvc? |
| 14:29:25 | Torne | no. |
| 14:29:45 | Torne | instructions for setting up a build environment and compiling are on the wiki |
| 14:29:57 | Torne | if you are on windows, the preferable way is to ru nlinux in vmware/virtualpc/similar |
| 14:30:10 | Torne | it's possible to do it with cygwin but we don't recommend it |
| 14:30:13 | Mataniko | yeah i have one ready |
| 14:30:24 | Torne | ok, then just follow the linux setup/build instructions |
| 14:30:31 | Torne | should be easy if you have linuxa lready set up |
| 14:30:56 | Mataniko | thanks alot for the info |
| 14:31:43 | Torne | no problem. if you search for "car head unit" or similar on the forums you can probably find an example of what you nede to change in the code to identify it as a different device |

| 15:00:18 | [Saint] | I believe it goes to partition 0, yes. |
| 15:00:31 | [Saint] | i'm not 100% certain however. |
| 15:00:57 | amee2k | but all the rockbox stuff goes into /.rockbox on the second partition? |
| 15:01:12 | [Saint] | correct. |
| 15:01:41 | amee2k | hmmm |
| 15:01:42 | amee2k | wait |
| 15:01:43 | [Saint] | with the exception of the bootloader, aplied seperately. |
| 15:02:12 | amee2k | okay, i just went on to switch to RB but rockbox utility says "error reading partition table - possibly not an ipod" ?! |
| 15:02:49 | * | [Saint] shrugs |
| 15:03:07 | [Saint] | this is why I recommend using iTuens if possible. |
| 15:03:16 | [Saint] | *iTunes, rather. |
| 15:03:30 | amee2k | itunes for some reason insists it can't contact the update server |
| 15:03:45 | amee2k | it only recommends that i "check my network connection" |
| 15:03:51 | [Saint] | firewall? |
| 15:04:03 | amee2k | well, i just downloaded it so from the OS to the internet is fine |
| 15:04:12 | amee2k | its a windows box |
| 15:04:15 | amee2k | no firewall |
| 15:04:37 | [Saint] | windows firewall may be blocking communication until you allow it. |
| 15:04:43 | amee2k | lol |
| 15:04:52 | amee2k | first thing you do on windows is disable the windows firewall |
| 15:05:08 | amee2k | then updates and remote registry access lol |
| 15:07:10 | [Saint] | well, I have no idea why...but the problem appears to lie with your machine/iTunes installation. |
| 15:07:21 | [Saint] | I just tried from here, and it's working fine. |
| 15:07:34 | amee2k | its my flatmate's box for testing windows stuff and gaming |
| 15:07:53 | [Saint] | You can also try the older version of iPodUpdater that doesn't need net access. |

| 19:43:05 | TheSeven | TheLemonMan: that depends on the kind of hardware :) |
| 19:44:34 | TheLemonMan | imx23 specifically, but its more a theoric question |
| 19:45:48 | pamaury | then go ahead :D |
| 19:47:10 | TheLemonMan | whats lradc about ? i just know it has channels and channel 7 is for battery charging |
| 19:47:48 | pamaury | low resolution analog-digital converter ? |
| 19:48:33 | pamaury | you put an analog wire on a pin and the hardware convert this to a number which is an approximation of the voltage on the pin |
| 19:48:57 | TheLemonMan | oh, good, got that |
| 19:48:58 | pamaury | for example, you put the battery output and it gives you thr battery voltage |
| 19:49:45 | pamaury | the hardware has a number of physical channels (pins) and a number of virtual channels which do the approximation usually. You map a physical one to a virtual one |
| 19:50:14 | TheLemonMan | in the first stage bootloading phase its disabled, is this normal ? |
| 19:50:48 | pamaury | A virtual channel can do lots of intelligent stuff like triggering an interrupt each time a value is ready, accumulate to have a better precision, ... |
| 19:51:26 | pamaury | Don't know, there is a no such a thing as "normal behaviour" for that kind of things ;) If you don't care about the battery voltage, you are free to ignore it |
| 19:51:51 | pamaury | Furthermore, you might want to disable it to avoid interrupts |
| 19:52:43 | pamaury | or to reduce power consumption perhaps ? |
| 19:53:31 | | Join Keripo1 [0] (~Keripo@mey081.wlan.design.upenn.edu) |
| 19:53:36 | pamaury | the imx23 has a battery brownout circuirty but I don't know if it relies on the channel being enabled; or perhaps it just can't be disabled and the code just disable the configuration registers |

| 19:54:55 | pamaury | I also find lots of power-related code in the fuze+ bootloader |
| 19:55:58 | TheLemonMan | the strange fact is that the interrupt is disabled but scheduled |
| 19:58:12 | jessmanboo | Hoping this is where I ask: Will someone please enable my Foswiki account? I have stuff to add in PluginMpegplayer. |
| 19:58:29 | jessmanboo | oh, duh. The Wikiname is JesseNoordegraaf |
| 20:00 |
| 20:00:02 | TheLemonMan | It is ANDed with its |
| 20:00:02 | TheLemonMan | corresponding interrupt enable bit to request an interrrupt." |
| 20:00:31 | gevaerts | jessmanboo: done |
| 20:00:56 | TheLemonMan | this part is a bit unclear, doesnt state if it's ANDed only by the interrupt dispatched or ANDed before being written back into the register |

| 20:01:08 | Zagor | gevaerts: ok |
| 20:03:01 | TheSeven | TheLemonMan: sometimes those IRQ flag bits are cleared when writing one to them and untouchend when writing zero |
| 20:03:27 | TheSeven | so writing zero to the enable bit and one to the irq flag bit is probably the usual way to disable it |
| 20:04:28 | TheSeven | and the phrase you quoted probably just means that if the chip asserts that bit, and if the enable flag is set, it will generate and interrupt :) |

| 22:43:43 | TheLemonMan | very good :D, so we're working on the same target |

| 22:45:39 | pamaury | I have some reserved bits written in a usb register |
| 22:45:45 | pamaury | in a clock control register |
| 22:46:31 | TheLemonMan | oh, you got really far |
| 22:46:32 | pamaury | in a emi control reg too |
| 22:46:59 | | Part Zagor |
| 22:47:19 | pamaury | no don't worry, that's early usb, probably just to check if usb is connected or not |
| 22:48:05 | pamaury | apparently, I haven't found anything strange in power registers but there is so much power-related code that I didn't check everything |
| 22:48:52 | kugel | JdGordon: you have one of the phones where rockbox uses more than 0% while idle right? |
| 22:49:02 | JdGordon | ineed i do |
| 22:49:05 | TheLemonMan | luckyily samsung splitted the bootloader in 2 parts |
| 22:49:18 | kugel | JdGordon: want to try a patch that hopefully makes it better? |
| 22:49:23 | TheLemonMan | one that handles mostly power management and "Dawit" that handles everything else |
| 22:49:29 | JdGordon | sure, but can you do the build for me? |
| 22:49:33 | JdGordon | 480x800 |
| 22:49:40 | TheLemonMan | with console via uart and alot of POST :D |

| 22:54:43 | TheLemonMan | good, i have a lil doubt about HW_POWER_LOOPCTRL, a function does ((REG32(HW_POWER_LOOPCTRL) << 0x12) >> 0x1F), it gets the lower bit of the scale factor, sounds right ? |
| 22:55:14 | JdGordon | kugel: actually, can you do two builds? one with and without the patch incase the new sdk fixes it or makes it worse? |
| 22:55:26 | pamaury | let me have a look |
| 22:55:51 | kugel | JdGordon: patched built is on the same url as always |
| 22:56:11 | JdGordon | ok, i'll get it at work |
| 22:57:27 | kugel | unpatched is same location, but filename is rockbox-480x800-2.apk |
| 22:57:41 | pamaury | TheLemonMan: I would say that it picks the 13rd bit of the register, that's a msb if of EN_RSCALE, seems rather strange |
| 22:57:50 | pamaury | *-if |
| 22:57:54 | kugel | oh, it has some plugins enabled |
| 22:59:02 | TheLemonMan | i dont know what i should think :| maybe they support only 0 and 2 scale factors ? |

| 23:28:35 | | Quit pamaury (Remote host closed the connection) |
| 23:29:20 | JdGord | Where is the CPU time coming from? If the activity is hidden the system shoould be dead unless music is playing |
| 23:29:34 | kugel | tick timer |
| 23:30:25 | JdGord | Can we kill it? |
| 23:30:31 | kugel | no |
| 23:30:51 | JdGord | Unless playback is running we don't care about responsiveness if we are hidden |
| 23:31:00 | JdGord | So just stop doing ticks |
| 23:31:15 | gevaerts | It's probably possible to make it smarter |
| 23:31:34 | kugel | i need it |
| 23:31:47 | tmzt | you can only be woken up from java right? |
| 23:31:51 | JdGord | For? |
| 23:32:00 | kugel | resuming playback via multimedia buttons |
| 23:32:22 | gevaerts | polling? |
| 23:32:32 | JdGord | That's gibe. Pause the tick counter and only send that tick event when it happens |
| 23:32:43 | JdGord | Gibe/fine |
| 23:33:20 | kugel | the scheduler needs the tick |
| 23:33:45 | JdGord | Not when we aren't active |
| 23:34:06 | kugel | wrong |
| 23:34:16 | gevaerts | I'm pretty sure we need timer things, but I'm not convinced that we need a steady 100Hz tick |
| 23:34:29 | kugel | our threads can't run without the ticks, and you thus couldn't resume playback |
| 23:34:43 | gevaerts | Why can't they? |
| 23:35:05 | JdGord | Yes but when we are inactive. If current_tick is paused nothing will complain |
| 23:35:09 | kugel | because the scheduler is a sleep when no thread is runnable |
| 23:35:27 | kugel | and the scheduler can only be awaken by a tick |
| 23:35:34 | JdGord | Tit will look like no time passes |
| 23:35:46 | gevaerts | sure, but you can predict when it will be needed next, and suspend the tick for that long |
| 23:36:12 | JdGord | And force ticks yo happen on wakep |
| 23:36:17 | gevaerts | There's no need to check 100 times a second if a 5 second sleep has elapsed yet |

| 23:36:53 | gevaerts | I'm not saying this is trivial to do with the current code, but there shouldn't be fundamental issues |
| 23:37:37 | JdGord | And obviously we aren't saying we could do a ticjless system |
| 23:37:50 | * | gevaerts is, actually :) |
| 23:38:06 | kugel | JdGord: i thought you meant to say that |
| 23:38:35 | JdGord | No. Just not send any ticks when inactive |
| 23:39:21 | JdGord | They come from Java anyway right? |
| 23:40:17 | kugel | not with my patch |
| 23:40:48 | kugel | JdGord: ordering by load in osmonitor, rockbox is the 2nd last process (last is init) |
| 23:40:58 | kugel | I'm fairly sure you can't do better than this |
| 23:41:11 | gevaerts | by load, sure, but wakeups can be expensive |
| 23:41:56 | kugel | what tool can show those (except powertop)? |
| 23:42:01 | gevaerts | Wanting to run three instructions 100 times a second might well eat more battery than doing significant things every two seconds |
| 23:42:50 | kugel | ohh, powertop is even installed |
| 23:43:38 | * | JdGord is fairly confident that if Java sends the threads we could be literally 0% CPU while inactive |

| 23:47:29 | kugel | JdGord: no idea |
| 23:47:47 | kugel | gevaerts: it seems I have ~1000 wakeups/s in total |
| 23:48:00 | kugel | half of them are in-kernel |

| 23:54:03 | JdGordon| | kugel: in svn ticks come from a java timer right? the c then incrememnets current_tick? |
| 23:55:44 | kugel | yes |
| 23:55:52 | kugel | and runs call_tick_tasks() |
| 23:56:25 | JdGordon| | ok, so when we are incactive (activity hidden and no music playing) there is no reason the current_tick needs to incremenet |
| 23:56:45 | JdGordon| | so disable the timer, or drop it to 1HZ or slower |
| 23:56:59 | JdGordon| | when something happens which does need the tick to happen we can force it |
| 23:57:39 | JdGordon| | multimedia keys might need a few ticks to get registered but that is still better than 100HZ for no reason |
| 23:58:42 | JdGordon| | actually, multimedia keys are irrelevant when no music is happening |
| 23:58:55 | JdGordon| | if music is playing the ticks would happen as normal |
