| 00:00:04 | yuriks | I see. I spent some time reading the rockbox code to see how usb currently works, and also reading about USB and the USB spec |
| 00:03:40 | yuriks | I don't think I'm up to the task, however. But the noisyness of this laptops internal audio system inspired me to take a look :) |
| 00:08:40 | pamaury | if I have time I can try to have a look. The problem is that to start hacking on this you need to know many things: rockbox, USB, USB Audio, usb controller, it takes a lot of time |
| 00:09:35 | yuriks | yeah, I don't really know any of them :D (only hacked on some of the rockbox font code a long time ago) |
| 00:10:25 | pamaury | I see, well try poking at me regularly, you might suceed in making me write some code, if I have some free time |
| 00:10:51 | pamaury | I'm going to bed now |
| 00:12:11 | yuriks | hehe, wouldn't want to be a bother |
| 00:12:11 | yuriks | bye |
| 00:12:30 | mg_ | yuriks: hah, well, it's a killer feature! |
| 00:12:55 | yuriks | mg_: would certainly make a very good and cheap DAC available |

| 00:26:34 | [Saint] | I seem to recall the RRP being somewhere in the vicinity of $1200, plus an extra $200 for the vac tubes. |

| 00:26:49 | [Saint] | haha |
| 00:28:06 | [Saint] | I use the FiiO E12 almost exclusively, though. Not anywhere near as pretty as the WA7, but actually portable. |

| 00:34:33 | [Saint] | I found some Grado Labs SR80's at a pawn shop the other day for $40 :p |
| 00:34:58 | yuriks | man, you guys and your audiophilism |
| 00:35:07 | yuriks | the most audiophile things I have are a Xonar DG |
| 00:35:17 | yuriks | and $40 sony in-ears |
| 00:35:56 | [Saint] | The _most_ audiophile-esque item I posses is likely my UE18 Pros. |
| 00:36:10 | [Saint] | I absolutely couldn't live without them. |
| 00:37:34 | copper | blah Grado |
| 00:38:25 | [Saint] | c'mon...tell me you wouldn't have got them at $40. |
| 00:38:36 | [Saint] | They look badass. |
| 00:38:42 | copper | I've thought about it, but on-ear, and no bass |
| 00:39:01 | [Saint] | The bass response from the SR80 is actually bloody nice. |
| 00:39:22 | [Saint] | I was fairly surprised, considering the open design and relative simplicity of the drivers. |

| 00:42:48 | copper | they're a Sure Thing™ |
| 00:42:56 | [Saint] | At $40 I couldn't not buy them. I suspect you'd be in a similar position, if not only to pass them on to someone who is interested, and make a reasonable profit. |

| 01:35:12 | *** | Saving seen data "./dancer.seen" |
| 01:41:25 | Pierluigi | just checked xrick in, if anyone could test it on a iriver h120 it would make my day (mind: SUBDIRS needs to be tweaked) |
| 01:41:49 | [Saint] | Pierluigi: are you aware of our simulator? |
| 01:42:03 | Pierluigi | eh yes sure |
| 01:42:04 | [Saint] | It is usually assumed the author will test on simulated targets. |
| 01:42:09 | Pierluigi | it works on sim |
| 01:42:24 | [Saint] | Then it'll almost certainly work on real hardware. |
| 01:42:29 | Pierluigi | but needs some proper test on hardware with diagonals and stuff |
| 01:43:27 | Pierluigi | also I didn't deliberately add keymappings for targets other than iriver/ipod cause I don't know what the real hardware can do and what button mappings are best |
| 01:44:42 | [Saint] | I think we might have some licensing issues here... |
| 01:44:55 | [Saint] | For example, who is "BigOrno"? |
| 01:45:06 | [Saint] | We're going to need a real name. |
| 01:45:13 | Pierluigi | bigorno is the nickname used by the original author of xrick |
| 01:45:27 | [Saint] | Right, we need a real name. |
| 01:45:39 | Pierluigi | hmm actually I need to add also readme to the check-in |
| 01:46:25 | Pierluigi | but dunno what's the usual place for that |
| 01:47:26 | Pierluigi | anyway if people comment the patch I can tweak things accordingly then |
| 01:48:16 | [Saint] | This is going to be problematic I believe. The author clearly states that anyone using the code must adhere to his license, but the license is *hilariously* vague, and makes a reference to the fact that it contains content that cannot be GPL'ed. |
| 01:49:01 | [Saint] | ""in the spirit" of the GNU GPL" is really rather meaningless. |
| 01:49:53 | Pierluigi | saint you already discussed this yesterday I believe |
| 01:50:11 | Pierluigi | the game engine is partly BigOrno code and partly my code |
| 01:50:24 | Pierluigi | I've stripped out ALL hardcoded (read: copyrighted) data |
| 01:51:07 | Pierluigi | so his (and hence my) code is released AS IS, in the "spirit" of GPL |
| 01:51:54 | [Saint] | "in the spirit" on GPL won't cut it, sadly. It needs to be GPL. |
| 01:52:41 | [Saint] | It may be better to reimplement the sections writting by whomever BigOrno entirely. |
| 01:52:47 | [Saint] | *written |
| 01:52:50 | Pierluigi | now I agree that's terribly vague, but the port is there, done and working |
| 01:53:16 | [Saint] | Yes. But attribution is going to be problematic. |
| 01:54:09 | [Saint] | And you're correct, my apologies, I hadn't noticed the offending data had been stripped out. |
| 01:56:11 | [Saint] | If you are able to contact the original author, you may be able to ask them directly if adding their real name for the sake of licensing and attribution is something he or she would be willing to do. |
| 01:56:37 | [Saint] | If not, the only option available would be reimplementing all the sections attributed to him or her. |
| 01:57:08 | Pierluigi | yes, already contacted. He is willing to tweak the README, and I'm very happy for it to happen, but he's very busy atm |
| 01:57:35 | Pierluigi | that's out of the question |
| 01:57:54 | Pierluigi | so much code |
| 01:58:13 | [Saint] | Well, just so we're clear, one of those two things needs to happen. |
| 01:58:52 | Pierluigi | I understand |
| 02:00 |
| 02:03:06 | Pierluigi | well, I'll try to get in touch with him again, but please you main mantainers have a discussion about what is ABSOLUTELY needed licence-wise and post a comment in gerrit about specific changes that need to happen (both licence-wise and code-compliance wise) |
| 02:04:37 | [Saint] | The game data itself appears to be the main issue, and from your port, I can't immediately tell where its coming from. |
| 02:04:50 | [Saint] | ie. sounds, maps, sprites. |
| 02:05:16 | Pierluigi | game data you'll have to download a zip from my repo |
| 02:07:30 | [Saint] | The main issue at this point would be attribution then I believe. |
| 02:09:47 | [Saint] | But I really don't understand how the original licensing (and its vagueness) and the fact that it states in several places that the original license and notices _must_ be kept is going to affect us. |
| 02:11:58 | Pierluigi | I guess the README should just be kept in game own subdir and then comments will be in line with where the game sources are, so at that point it should be ok |

| 14:31:27 | fs-bluebot | Gerrit review #984 at http://gerrit.rockbox.org/r/984 : qeditor: add register diff tab (WIP) by Amaury Pouly |
| 14:31:48 | pamaury | it is very basic, missing ton of stuff and is a bit ugly but it should work |
| 14:31:48 | wodz | pamaury: great! |
| 14:33:22 | pamaury | for information, there are a few things which are still WIP: being able to change color theme (default is blue for diff, red for error), also theming only apply to register tree at the moment but it will also apply to the panel soon. Also soc and dev panel will display the list of differences, and I will also add a checkbox to only display differences instead of everything |

| 20:32:04 | Dynion | @ copper, got me a clip+. You were right once more ;-) |
| 20:32:19 | Dynion | also, 72gb clip+ is kinda fun |
| 20:32:19 | copper | about what? |
| 20:32:33 | copper | yeah it's a nice player |
| 20:32:36 | Dynion | about 64gb |
| 20:32:43 | copper | I've thought for a long time that it was "too damn small" |
| 20:32:44 | Dynion | about it being not that much less than a classic |
| 20:32:50 | copper | but it's just really portable |
| 20:34:01 | Dynion | yup |
| 20:34:07 | Dynion | a lot better for cycling |
| 20:34:21 | Dynion | and a lot less stress on the jack port as the weight is close to 0g |
| 20:34:41 | Dynion | just having a little trouble with the bass, but i'm sure i'll figure it out |
| 20:34:54 | copper | there's bass boost in the sound settings |
| 20:35:05 | Dynion | i don't want it boosted |
| 20:35:07 | copper | or, the parametric EQ, if you feel adventurous and read the manual section about it |
| 20:35:10 | Dynion | i want it less littery |
| 20:35:16 | copper | "littery"? |
| 20:35:22 | Dynion | messy? |
| 20:35:30 | Dynion | littery is a word afaik |
| 20:35:44 | Dynion | disordered |
| 20:35:47 | Dynion | something like that |
| 20:35:55 | Dynion | it's not tight |
| 20:38:48 | copper | the Clip's frequency response is ruler flat |
| 20:39:03 | Dynion | i saw that, astonishing |
| 20:39:05 | copper | the bass it produces is exactly what's in the recording |
| 20:39:33 | copper | if you don't like what you hear, maybe it's the track you're listening to, or maybe your headphones |
| 20:40:13 | Dynion | well, currently i'm testing all the cool 24bit 192khz flacs on headphones for testing |
| 20:40:14 | Dynion | :p |
| 20:40:33 | Dynion | its possibly a bit too demanding, high and mids are lovely though |
| 20:41:31 | Dynion | also, very, very well done on the speed its loads big tracks like that |
| 20:41:46 | copper | high sampling rates and bit depth are useless for playback |
| 20:42:06 | Dynion | i defenitely hear it on my stereo set |
| 20:42:09 | copper | and Rockbox resamples it all to 16 bit / 44.1 kHz (or 48 kHz if you set it in the settings) |
| 20:42:35 | Dynion | definitely* |
| 20:42:58 | Dynion | no idea how it is on rockbox, they're my main test tracks for speakers |
| 20:43:12 | Dynion | so good reference for me:p |
| 20:44:06 | Dynion | you may be right though, i havent listened to these headphones in a while, lets try my iem's |

| 21:14:56 | wodz | foolsh: thats easy enough - start reading dissasemblings :-) |
| 21:27:14 | ParkerR | Any progress on the Sport? |
| 21:28:11 | yuriks | not doable, afaik |
| 21:29:48 | wodz | yuriks: To be more exact we honestly don't know. The brief on Actions www suggest the SoC used has very tiny memory BUT this looks pretty strange considering relatively large color display. |
| 21:30:31 | yuriks | wodz: from the screenshots I've seen the display is large but pretty barebones detailwise, so it doesn't look like they have a lot to work with |
| 21:31:06 | wodz | yuriks: you need keep framebuffer somewhere still |
| 21:31:46 | yuriks | maybe the LCD controller has a builtin FB? |
| 21:32:17 | wodz | 128x128x16bit is 32kB for framebuffer alone |
| 21:32:43 | wodz | yuriks: yes that is possible |
| 21:33:44 | wodz | I have never seen such lcd controller in consumer product though. SDRAM is way cheaper then dedicated sram in controller |
| 21:35:17 | wodz | It may be they used customized version of SoC with bigger builtin ram or they use paging |
| 21:35:30 | wodz | there are a few possibilities and we simply don't know |
| 21:35:34 | *** | Saving seen data "./dancer.seen" |
| 21:35:52 | yuriks | http://www.actions-semi.com/en/productview.aspx?cat=87&id=118 |
| 21:36:06 | yuriks | judging from the RAM bank sizes there |
| 21:36:07 | foolsh | there was a lcd screen on a blog I read a few months ago touting its built in capabilities, but I'm probably way out in left field some where with this |
| 21:36:40 | yuriks | it sounds very possible they're dedicating two fo them to the FB |
| 21:36:50 | yuriks | it's not like the chip doesn't have RAM, it's just weirdly organized |
| 21:38:23 | yuriks | also, anyone have any clue what a BROM is? |
| 21:38:47 | wodz | boot rom |
| 21:39:30 | yuriks | ah |
| 21:39:35 | wodz | it used to be masked rom on other atj SoCs |
| 21:40:59 | yuriks | it would be possible to check feasibility if someone could get the firmware and descramble it |
| 21:42:19 | wodz | with mips 4k core you can circumvent wierd memory banks thanks to MMU but still described memory size is not even in hundreds of kBs |
| 21:43:02 | yuriks | and with me seeing pictures featuring graphical menus and cover art, it's a pretty sure bet that there's more RAM in there somewhere |
| 21:43:41 | wodz | its 127kB in total according to www |
| 21:44:00 | pamaury | wodz: virtually all smart lcd have a framebuffer |
| 21:44:11 | ParkerR | "smart lcd"? |
| 21:44:28 | ParkerR | Also the Zip (and I think Sport) are OLED :P |
| 21:44:32 | wodz | yuriks: that is what I said |
| 21:44:35 | pamaury | lcd with a controller |
| 21:44:41 | ParkerR | Ahh |
| 21:44:47 | yuriks | wodz: yup |
| 21:45:26 | pamaury | as long as you don't run it in VSYNC or DOTCLK mode, you don't need a framebuffer in memory |
| 21:45:29 | wodz | pamaury: yes but usually this is not true framebuffer (from the point of the software) - just some internal memory you can push data to through fifo |
| 21:45:51 | pamaury | you can read/write it in a random access fashion |
| 21:45:55 | pamaury | although it's damn slow |
| 21:46:25 | wodz | pamaury: the read part is usually omitted |
| 21:47:30 | wodz | you can simulate this to some degree with windowing functions and hw alpha support though |
| 21:47:39 | pamaury | well, I admit it's true the read signal is hardly ever wired, *but* it is the case in a few cases, like the fuze+ |
| 21:47:52 | wodz | lucky you! |
| 21:48:17 | pamaury | and it's used to read the controller ID to distinguish the LCD type |
| 21:48:37 | wodz | Internal (16K+12K)*8 BROM built in boot up and USB Upgrade firmware and C-library |
| 21:48:51 | wodz | the last part is pretty peculiar |
| 21:49:10 | pamaury | indeed that's very small |
| 21:49:25 | wodz | I mean C-library part |
| 21:49:44 | pamaury | but why a C library in ROM ?! |
| 21:49:55 | wodz | to save space in ram |
| 21:50:31 | wodz | and build illusion you have all building blocks in place (hw drivers wrapped in some api) |
| 21:51:18 | pamaury | anyway, with this small amount of RAM you either have a trivial firmware or use paging |
| 21:51:36 | yuriks | the firmware update file has ~uniform entropy :P |
| 21:52:05 | pamaury | does it have a DSP ? |
| 21:52:06 | yuriks | stupid scrambled images |
| 21:52:10 | yuriks | pamaury: it does |
| 21:52:31 | yuriks | you can remap RAM between the MCU/DSP, acoording to the product page |
| 21:52:53 | wodz | yuriks: You can actually decrypt the firmware update file with descrambler in our repo. The tool doesn't understand the format of decoded binary though |
| 21:53:28 | yuriks | wodz: I was trying to look for that. I can't get my away around the buildsystem or finding anything in the repo :| |
| 21:53:50 | yuriks | I'm trying to read some code I resorted to mangling the output of make to figure out what files are being included in the build :P |
| 21:54:12 | wodz | rockbox/utils/atj2137/atjboottool |
| 21:54:35 | wodz | thats the tool |
| 21:54:36 | pamaury | cd utils/atj2138/atjboottool; make |
| 21:55:14 | pamaury | wodz: by the way, I don't remember, does it correctly descramble everything or are there still some unknown bits ? |
| 21:55:59 | yuriks | ah, it's specific to the thing, not a generic one |
| 21:56:06 | * | yuriks has to go to work |
| 21:56:28 | pamaury | yeah, we have many specific descrambles/tools in utils/ |
| 21:56:35 | wodz | pamaury: The descrambling goes fine (well I can't remember if the trailing bytes are cut off or not). It is just that descrambled binary is further packed/scrambled/crypted |
| 21:57:33 | pamaury | can you disassemble it or is it scrambled ? |
| 21:58:01 | | Quit y4n (Quit: PANTS OFF!) |
| 21:58:34 | pamaury | you talked about finding the lcd routine so you must have the code somehow |
| 21:58:56 | wodz | strings doesn't return anything useful so I suspect it to be further scrambled |
| 21:59:19 | wodz | pamaury: I was talking about e150 not clip sport (re lcd init) |
| 21:59:29 | pamaury | ah yeah |
| 22:00 |
| 22:00:45 | pamaury | we would need access to the ROM and dump it, if it can do firmware upgrade |
| 22:02:59 | wodz | That should be possible. If we are lucky enough adfu mode should be similar to s1mp3 and atj213x. The nand data pins needs to be shorted to force flash fault which should expose rom adfu |
| 22:03:47 | wodz | clip sport has jtag pins on PCB which makes another attack vector |
| 22:03:56 | pamaury | yeah, that's worth trying once we have working hwstub on atj213x |
| 22:04:21 | pamaury | jtag is nice if it's not disabled or crypted |
| 22:04:30 | wodz | pamaury: to dump rom you don't need hwstub. adfu can read arbitrary memory |
| 22:04:44 | pamaury | oh really ? |
| 22:05:03 | wodz | yeah, thats how I dumped atj2135's rom |
| 22:05:23 | pamaury | you should buy a sport and try it ! :p |
| 22:05:43 | wodz | could be fun but I really don't have time |
