#rockbox log for 2017-01-20

00:00:19pamauryah, that means a lot of nesting potentially
00:01:35jhMikeSup to 10
00:02:13*furrywolf isn't familiar enough with the architecture or the systems in question to be of any help

00:09:23hoshipamaury: how nwz ports are going? is there a ipod nano 5g exploit?
00:09:49chrisjjfurrywolf, re your USB plug/unplug crash related possibly to playlist, you might want to try on a clear install of .rockbox before you do any playback. 'Cos
00:10:17jhMikeSpamaury: The IRQ stack, which irq_handler initially uses, is adequate. worst case: 400 bytes because entry saves 10 words
00:11:14furrywolfchrisjj: I've been though several clear installs, including a complete reformat of the internal storage.
00:12:19chrisjjBut did you try USB before any playback?
00:12:31pamaurychrisjj: we've already ruled out and narrowed down the problem, please don't add any more confusion
00:13:11pamauryhoshi: not much problem, I didn't have time to work on it in the past week
00:13:26chrisjjIf you've ruled out any sensitivity to playlists, I missed that. Sorry.
00:13:32jhMikeSbilgus: btw, you do get keyclicks in USB mode. You could have voice left operating too.
00:13:41hoshiEhh, I wish Nano 5g could be hacked
00:13:52furrywolfchrisjj: yep. it even crashes with no playlist in existence, off a fresh install.
00:14:05chrisjjfuttywolf, if you feel my suggestion of one simple test adds confusion, please do ignore it! ;-)
00:14:13chrisjjAh, got you. Oh well.
00:16:29chrisjjfurrywolf, re your statement that it tries to reload the playlist each time, how do you know it is trying to load the playlist?
00:16:48furrywolfchrisjj: because it says "loading" and a percentage that counts upwards
00:16:49pamauryhoshi: I think it's unlikely anyone is trying to find an exploit on the nano 5g
00:17:04hoshiYeah I know, maybe someday...
00:17:16chrisjjSays Loading... . Doesn't say Loading playlist...
00:17:17hoshiIt's shame that they released 4g exploit so early.
00:17:28jhMikeShaha, presentation mode!
00:17:54furrywolfno, no it doesn't. is it loading something else, that takes longer as the playlist is larger?
00:18:26*pamaury think there is approximatelly -1% chance the problem is related to playlist
00:19:09hoshipamaury: Forums don't works?
00:19:15furrywolfI think something is leaking, possibly the playlist, but it is only showing up due to the unrelated usb issue. which is what I've said all along. :)
00:19:41pamauryhoshi: the server hosting forums has a problem, it's random up and down
00:19:49hoshiOk, thanks

00:21:15Mihailbilgus: you mean are we break amsv2 usb again? :)
00:21:23bilgusyeah :/
00:22:11pamauryThe old had at least the benefit of being (as far as we know) correct wrt to i2c, we "just" need to find its problem on amsv2
00:22:58pamauryis the clip+ or zip broken if we revert ? I may try it on mine this week-end to see if I can find anything
00:23:12chrisjjfurrywolf, I like that answer much better :-)
00:24:32bilgusno clue on the zip
00:24:36Mihailpamaury: we don't have datasheet for i2c on amsv2 so ...
00:25:02bilgusthe clip+ takes a very long time to enumerate if it ever does
00:28:07pamauryMihail: I mean it's not lock a mutex in an interrupt ;)
00:28:33bilgusI guess thats the 3543v2
00:29:20pamauryat least this i2c code doesn't look too complicated

00:53:43furrywolfdoesn't work
00:53:59furrywolfwhat do you keep changing between this?

01:17:50bilgusis your head current when you did the reversion?

01:22:48bilgusso it works?

01:24:56bilgusas far as I know it is only affecting the Fuzev1

01:43:08prof_wolfffthere are known OOM issues related to usb connect-disconnect when the playlist is being loaded
01:44:29furrywolfprof_wolfff: Mihail has identified the exact patch that keeps my fuze v1 from connecting, and is trying to figure out why now.
01:45:01prof_wolfffok, thanks, could not read the whole conversation yet
01:47:39furrywolf;a=commit;h=c7daef36c5c75b8541d38cec4793826ab085d5ad some part of that makes usb not work, as it handles the communications for detecting usb and charging.

02:03:54jhMikeSyou're locking mutexes in an ISR
02:06:41jhMikeSthis driver can't be non-interrupt based unless you're gonna constantly poll hardware (which is just a waste of cycles)
02:08:17furrywolfyeah, I don't like polling.
02:08:36jhMikeSand it's doing everything it isn't supposed to, like lockout out interrupts for a transfer, which causes audio dropout (even worse case for recording)
02:09:09jhMikeSthe dropouts were a reason for decreasing interrupt latency in the first place, which fixed them but now it's messed up again
02:10:02jhMikeSthat patch breaks a lot of stuff
02:11:56furrywolfunfortunately, that patch apparantly also fixes a bunch of stuff for some other players...

20:39:23pamauryso when it crashes like this (without watchdog), does a power key reset boots the player or do you need to hit the reset button?
