00:10:40gevaertsDo you have the font pack installed?
00:10:44bertrikmaybe you need the extra fonts

00:19:00wodzgevaerts: thanks for testing. 0x709ec is actual memory access in safe_read32() function used by unwarminder which means it crashed earlier and tried to unwind stack which pointed to some faulty address.
00:19:16gevaertsah, interesting
00:20:04gevaertsI did find that same address a bit suspicious :)
00:20:36wodzanyway v10 is a progress still

00:20:45gevaertsDefinitely

00:21:18fs-bluebotGerrit review #286 at http://gerrit.rockbox.org/r/286 : bFLT loader for plugins by Marcin Bukat (changes/86/286/10)
00:25:08wodzit seems to fix plugins which freezed in v8 but not this which data aborted
00:26:00gevaertsYes, I'd say those "fixed" plugins should check return values a bit more...
00:26:25wodzwhat you mean?
00:26:59gevaertsThey should have handled things a bit more gracefully, like dict does
00:27:12gevaertsi.e. check what get_buffer returns
00:27:18wodzah, yes
00:31:20wodzWell before fix plugin_get_buffer() returned whole plugin buff which lead to plugin code overwrite. dunno why dict chocked on allocation stage but it helped a lot to understand the problem.

11:16:59wodzTheSeven: how to use postmortem stub and what it gives? Pure mem dump?
11:17:12TheSevenwodz: read access to arbitrary memory locations
11:17:17TheSevenso it can be used to dump some hw state as well
11:17:35TheSevenso you have a panicing nano2g?
11:18:07TheSevenlast time I checked the postmortem stub didn't quite work for some reason, possibly because USB hardware state was screwed up too badly when it started
11:18:15wodzon my own request through g286

11:19:02wodzTheSeven: where are PC tools to interact with the stub?
11:20:06TheSevenno idea where it's hiding, but there should be an rbpms.py file somewhere
11:21:01wodzfind . -name rbpms.py gives nothing
11:21:29TheSevenhttp://www.rockbox.org/tracker/task/11701
11:21:31TheSevenhere it is
11:22:44wodzagh, Why not to commit it to git tree? With a bit of documentation ;-)
11:22:53TheSevenno idea why that didn't happen
11:23:03TheSevenI thought I had dropped it into the tools folder or something
11:23:19TheSevendoes the post mortem stub itself work?
11:23:27TheSeveni.e. do you see it in lsusb?
11:24:03wodzdon't know - first I wanted to gether all tools needed and failed
11:25:14wodzare there other debugging means emcore will give me? gdbstub or something?
11:26:59wodzTheSeven:^
11:28:51TheSevenwodz: emcore does offer some more debugging features, but no gdb stub (yet)
11:30:53wodzTheSeven: What is the cause of the lack of gdbstub? Technical difficulties or just nobody implemented one?
11:31:03TheSevenprimarily the latter
11:31:13TheSevencould be that some more infrastructure in the kernel would be necessary
11:31:29 Quit KiwiCam (Ping timeout: 276 seconds)
11:31:40TheSevenI tried to expose USB APIs for most things required by a debugger stub, but no idea if that's sufficient for GDB
11:31:42TheSevenprobably not
11:33:10TheSevenit provides some basic means of debugging though (logf via usb, memory access via usb, thread register state dump, ...)
11:37:29***Saving seen data "./dancer.seen"
11:40:53wodzTheSeven: I am interested in something different - I would like to run rockbox under control of gdb on target.
11:41:12TheSeventhat would probably require a lot of effort
11:41:20wodzwhy?
11:42:21wodzyou can rippoff basic arm gdbstub either from gdbserver of qemu and the bit left is communication driver
11:43:28wodzIn easier version this would be through UART, in more comfortable setup through usb-cdc driver or some custom one + some glue part on pc
11:50:55TheSevenhm, the usb part of that might be rather tricky
11:51:19wodzwhy?
11:52:24TheSevenwell the usb driver is a couple thousand lines of code
11:52:43TheSevenlet alone the cdc stuff
11:53:58TheSevenand we would probably need to patch up the rockbox startup code rather badly to make it not break the gdb's usb communication
11:54:57wodzwe could use some simple custom interface and pc glue part
12:00
12:00:14TheSevenhow does gdb keep control of the hardware while the application is running?
12:00:19TheSevenby means of a communication IRQ?
12:00:45TheSeventhis might mean that all kinds of critical sections in rockbox might screw us
12:01:41wodzYou usually set brakepoint which jumps to your stub
12:02:18wodzit is up to you how this is implemented. You can use hw assisted brakepoints or simply patch in memory

18:13:41TheLemonManis the internal nand read/writeable by rockbox on a clip zip ?
18:18:47bertrikTheLemonMan, the hardware presents it to us as an SD card, we can't access the raw NAND as far as I know
18:19:40TheLemonManbertrik: so its usable/used by rb, right?

18:27:28TheLemonManive read that the usb connection might be flaky sometimes
18:28:00lebelliumyes... with my theme most of time the USB connection doesn't work so I use the OF USB
18:29:58TheLemonManhuh? how is that related to the theme :P
18:30:34lebelliumdunno. It also occurs with other themes but I have the impression it occurs more often with mine.

18:57:21TheLemonManworst thing to debug
19:00
19:01:53WalkGoodlebellium i've never had an issue with usb other than the first few weeks of release, while i normally don't run a theme, i've been running dfkt's for around 2 weeks now and no issues either
19:03:33lebelliumIndeed, with the other themes it seems to work well. I have had USB issue for 10 months with my theme :) Maybe because my theme uses more memory than the others?
19:03:56lebelliumor maybe due to my 32GB microSD?
19:04:05WalkGoodhave you tried using less to see if your theory is right?
19:04:25WalkGoodi'm running a 32gb card as well

19:05:08WalkGoodhaven't tried yours, if you want i'll run it next for a few weeks
19:05:24lebelliumso if you have no problem with a 32GB card I would say it's related to the memory corruption saratoga is talking about or theme memory usage more globally
19:05:50WalkGoodthe latter sounds logical
19:06:36TheLemonManmeh modern targets all have 32/64 mb of ram
19:06:59TheLemonManyou usually never run out of memory unless you start using hi res png
19:08:32lebelliumthen I don't know why the Zip freezes 9 of 10 times when I connect it to the computer with my theme :)
19:08:59[Saint]because the Zip doesn't fall into that category? ;)
19:09:09[Saint]Its got nowhere near that RAM does it?
19:10:02lebelliumI don't know, I'm not really familiar with the debug menu
19:12:40[Saint]It _shouldn't_ matter, though, because the theme buffer should be able to infinitely steal from the playback buffer iiuc
19:13:32[Saint]a wps that stole all remaining buffer would kinda defeat the purpose though I imagine.
19:15:49lebelliumJust tried again to make sure.... the Zip won't connect to the computer and when I unplug the cable it remains on the USB connection screen. I have to reset everytime

19:48:02AlexPRI don't know, but the point is they don't suffer from spinning the disk up so don't need to buffer large amounts

21:30:32gmaxwellOkay, the reason I ask is that the testvectors have extensive frame size switching... where the files you encode with opusenc won't but they'll tend to have larger ogg pages.
