00:16:59pixelmabertrik: you looked for small bugs to fix but maybe you can have a look at the dutch translation update in the tracker instead?
00:24:44bertrikpixelma, I don't know the proper dutch translation for root, the patch in the tracker leaves it untranslated ...
00:33:18 Join grawity [0] (~grawphone@m83-178-88-15.cust.tele2.lt)
00:33:38pixelmawell, then there may be no proper translation and most people would use "root" in Dutch context too. There are some things I couldn't really "translate" to German either.
00:35:05grawityHey, does anyone here have a rockbox.ipod for nano2g that is at least one month old, and can email it to me? I want to compare the LCD contrast (seems quite low in today's build, unless it's just my eyes)
00:37:49saratogayou'll probably need to change the entire build, not just the one file
00:38:51grawityWell, the rest are just fonts, codecs, plugins.
00:39:39grawityrockbox.ipod seems to be holding the entire firmware or whatever it is called.
00:40:27pixelmaif you purely want to test the contrast the file would be enough but you won't be able to play music or games
00:41:51grawityTo play music I'd need codecs/ ?
00:42:16saratogato do anything you'll need a working rockbox install
00:42:27saratogai think the main binary will just get you the menus and not much else
00:43:01grawityIf you have an entire build from last month handy, it would be nice... Otherwise I'd settle for rockbox.ipod.
00:43:36pixelmaunfortunately daily builds don't get as far back anymore
00:44:51grawitysaratoga: The entire "install" consists of bootloader, firmware, plugins, codecs, and themes, plus some other files (tagnavi.conf and codepages, they never change), doesn't it?
00:45:08saratoganot the bootloader
00:45:25grawitypixelma: that's why I was hoping someone here is lazy at upgrading.
00:45:27saratogaand tagnavi.conf is your local settings file
00:45:48grawityNo, local is tagnavi_local.config
00:46:15grawityEr, _custom
00:46:42saratogaoh yeah
00:48:25*grawity remembers a backup of three-month-old rockbox somewhere.
00:49:19grawityI guess I could downgrade to that.
00:58:45*grawity wonders if r28190 could be the cause.

04:04:20S_a_i_n_twhen/why are bootloaders released?
04:05:12S_a_i_n_tthere's been a change to the Nano2G code that requires a new bootloader to be built, and as far as I can tell (unless what was implemented is broken which I doubt) RBUtil is still using the old Nano2G bootloader.
04:05:49S_a_i_n_t"change" == enable Nano2G to boot the OF by holding Menu during startup like the other iPods.
04:06:42S_a_i_n_tas of r28237
04:07:29saratogathey can be updated whenever someone feels like tagging new ones in SVN and then pinging the swedes to update the download site
04:07:30 Quit TheSeven (Ping timeout: 240 seconds)
04:08:32S_a_i_n_tAh, right. Well, building the Nano2G bootloader would be great. I'd be happy to pass it through the crypto on one of my Nano2Gs also.
04:08:58S_a_i_n_tI just don't have a dev environment set up presently.

04:42:28smartboyathomeSo, I'm thinking about developing a plugin, but I was wondering if there was any standard way to modify the database or (hopefully) the ID3 tags? I'd like to be able to change the rating of a song.
04:42:59saratogasmartboyathome: i'm not sure if thats in the plugin api, but if its not, you could add a function to do it
04:43:52smartboyathomesaratoga: is there any way to modify ID3 tags from within rockbox, or is that frowned upon?
04:44:10saratogawe don't provide code to do that, of course you're welcome to provide your own code in your plugin to do it
04:44:30saratogaor do you mean modify the database?

05:31:28soapand, gevaerts, "most people not liking file-only settings" is something I don't think is true of this. Many people would kiss your bum for the option to set it w/o a compile. It would be a set-and-forget for many so a one-time file change is small potatoes.

11:56:52badcamHi Guys. Do you mind if I ask a question about a theme issue I'm having?
11:58:29CIA-7New commit by 03nls (r28285): libtremor: tiny optimization 0.5%-1.5% on coldfire and PP
11:59:57pixelmabadcam: if it's a Rockbox theme then just ask
12:00
12:00:10CIA-7r28285 build result: All green
12:00:27pixelmaand be patient, not everyone will have an answer
12:05:26badcamGreat. Thanks. I've actually just answered the problem. I realise that there was a bitmap I hadn't copied into the WPS new theme folder. Now, I'd like to take a screenshot, but using system/debug/screendump and then plugging the usb cable in, doesn't work. I can get a screenshot with the emulator, but I'd really like to get it working on my Sansa ClipV2.
12:08:49badcamI'm using Linux Mint BTW :)
12:11:02pixelmasounds like it could be a limitation of the ClipV2 part but I don't know and don't own such a device
12:11:42pixelmaerr.. ClipV2 port
12:12:38S_a_i_n_tafaik screendump should be working...
12:14:10pixelmawell, from the description I don't thiink badcam is doing something wrong though and so I suspect there may be a bug in Rockbox which is why I said that
12:14:18badcamSorry. Port? I'm probably not following the instructions properly. After I have chosen Screendump and it confirms that it's enabled. I presume I just navigate to the screen I want a dump of and connect the USB cable. Correct?
12:14:49S_a_i_n_tCorrect.
12:15:51pixelmabadcam: in Rockbox for the ClipV2
12:16:31badcamOK. How long should the capture take? Does the Clip give any indication that it has done this?
12:16:45S_a_i_n_tIt should be instant.
12:17:05S_a_i_n_tYou're looking in the correct place?
12:17:15S_a_i_n_tthe files should be on the root of your DAP
12:18:18pixelmathere should be some dump-timestamp.bmp files
12:19:10badcamYes. Root directory. I'm trying a different screen location. Checking now...
12:20:54badcamNope. I'm just seeing the usual folders and files. No .bmp's. Hidden files are switched to on, not that that should make any difference.
12:20:56AlexPJdGordon: No I didn't and yes I did respectively :)

12:22:00badcamI've tried this on my Clip+ as well and no luck there either. Perhaps it's Mint?
12:22:37S_a_i_n_tIf I understand correctly, it just needs to detect power on the data pins, it shouldn;t matter what OS it is.
12:24:08badcamSure. Will do. Pins: I have a mini usb wall charger. I'll try it with that.

21:14:04gevaertsI haven't seen any recent stkov reports for nano2g
21:14:15kugelthe android port needs bigger stacks too, I don't think bigger stacks on a per-target basis is a bad thing
21:14:17TheSeventhere might be some hiding in the corners
21:14:53n1skugel: why does the android port need bigger stacks?
21:15:02kugelI don't know
21:15:03TheSevenfor example, there used to be one in battery_bench, which might have been caught by the fat rework, but i'm currently using a locally increased stack on mine
21:15:30kugelI guess bionic is a bit more bloated than our c library
21:15:53TheSevenbut I haven't hit any stkovs during everyday use since the fat code rework

21:20:23TheSevensince i don't have an explanation why it disappeared, i fear that it might just come back at any time

21:21:28gevaertsno idea
21:21:37gevaertsIt's 0x800 now
21:21:56TheSevenwhich is one sector on nano2g
21:22:07gevaertsUnless my brain is malfunctioning, 4*SECTOR_SIZE would leave this unchanged anywhere except on nano2g
21:22:15TheSevenprobably yes
21:22:16n1sthe screendump function shouldn't use more than 1k of stack or so, does it run in the usb thread?
21:22:23gevaertsn1s: it does, yes
21:22:23TheSevenyes
21:23:05TheSevengevaerts: do you remember how many on-stack buffers (worst case) the fat code is using?
21:23:15TheSevenIIRC you brought that down to two
21:23:32TheSevenor even one?
21:23:33gevaertsI can't remember if we managed to get it down to one or not
21:23:59gevaertsone
21:24:04gevaertssee r28011
21:24:12TheSevenhm. so where is all this stack space being used?
21:24:36TheSeven352 bytes for the LCD line, 2KB for the sector
21:24:49TheSevenand IIUC we have 3KB of stack
21:24:50gevaertsDEFAULT_STACK_SIZE is 1K, so the USB stack has 3K
21:24:54saratogadoesn't the 2G have tons of ram for a flash player? might as well bump the stack sizes for releases
21:25:03saratogathat way users are unlikely to run into problems
21:25:29TheSevensaratoga: yes, it doesn't really matter if we have 30 or 29.99MB or audio buffer :)
21:25:32n1sTheSeven: screen_dump has a MAX_PATH buffer too so ~600bytes in total for that func
21:25:45n1show big is the usb stack?
21:25:47TheSeven3K
21:25:54TheSevenlet me try bumping it to 4K
21:26:31n1sbtw, making that screendump code use a smaller buffer looks like it would be pretty easy
21:27:04TheSevenIIUC (DEFAULT_STACK_SIZE + SECTOR_SIZE + lcd width * lcd bytes per pixel) should be sufficient

21:33:04TheSevenwidth*
21:33:05gevaerts640
21:33:14TheSevenok, so another 1280 bytes for the line buffer
21:33:32n1sin fact, the buffer is entirely useless on the nano2g IIUC, all that code does is process one lcd framebuffer line with htole16 and then write it to disk, but since the nano has LE frame buffer data and LE cpu it could just write the lcd frambuffer directly to disk
21:33:34gevaertsBut on the other hand it has 512-byte sectors
21:34:00gevaertsSo we have 400 bytes margin...

21:34:23TheSeveni'd like to make the stack size DEFAULT_STACK_SIZE + SECTOR_SIZE if possible
21:35:30gevaertsThat would be ideal, but I wouldn't shrink the stack on any target one week before release
21:35:31TheSevenor maybe DEFAULT_STACK_SIZE + SECTOR_SIZE + BMP_LINESIZE

23:56:46TheSevengevaerts: what did you use to figure that out?
23:56:57gevaertsTheSeven: awk, sqlite, and some patience :)
23:57:03gevaertsoh, and objdump
23:57:12gevaertsTrying to clean it up now
23:57:35TheSevenso you're disassembling it and parsing the output?
23:57:40gevaertsbasically
23:57:52gevaertsI don't take variable arrays and push/pop into account yet
23:58:01TheSevenhm. why can't functions just have an attribute in the elf file that tells how big their stack frame is.
23:58:16gevaertspush/pop should be possible, but variable arrays are basically not doable
23:58:24gevaertsand recursion is of course a problem
