01:08:55speachywhat target for the ROLO error?
01:08:59mendelmunkis_builtin thanks
01:09:46mendelmunkis_bilgus: speachy: on my fuze+ my tests builds will occasionaly fail with a rolo bad checksum error then work next time I try them.
01:10:23speachycan't comment on that one. just fixed up some incorrect IDs causing ROLO failures on a few less-stable targets..
01:10:35_Bilgusso like are you copying the file to the device and then ROLO picks up the new file or are you calling rolo?
01:11:21_Bilguslike going thru the menus and manually selecting the firmware
01:11:34mendelmunkisI have a separate RBDIR for test builds. I'm running it from there.
01:11:50mendelmunkisIn other words calling ROLO
01:13:03_Bilgushmm thats odd I could see copying it failing but if it's already on disk... thats worse
01:13:53_Bilguscould you try putting your file on the sdcard and running it from there
01:14:39mendelmunkisIt's intermittent a file will error and then run the next time I try with the same file.
01:15:02mendelmunkisWhy would an sd card change anything?
01:15:46mendelmunkisIt's unlikely to be hardware given as I think it followed me across devices.
01:18:27_Bilgusits a pretty simple set of prerequisites for ROLO to load the file so if bad checksum then the checksum it calculated doesn't match
01:18:44_Bilguswhat causes that? bad data
01:19:23_Bilgusif its intermittent then its bad data from the file or something corrupting it
01:20:19_BilgusI've never seen bad checksum during rolo on fuze+ clipzip i've seen it on the clip+ but that was genuine
01:20:28mendelmunkisThats what I thought. but how does bad data get uncorrupted?
01:21:24_Bilgusthe read succeeds, if its at least slightly reproducible I'd put a splashf in the disk handler on re-read
01:21:44_Bilgusi'd say logf build but that is probably a bad idea
01:24:41_Bilgusyeah nm if it fails then you can still dump it
01:24:53_Bilgusand if not then who cares

02:27:12__builtinhmm... looks like I may have a race condition between the sound and model code
02:27:42__builtinthat would explain why the crash only occurs at high sample rates
02:29:53*__builtin thinks two threads might be allocating the same chunk of memory simultaneously
02:37:12*__builtin confirms that... disabling one of the conflicting threads eliminates the issue

03:01:06__builtinso anything in tlsf is rendered useless
03:02:34__builtinbut adding a couple of locks to zone.c isn't a bad idea, yes

13:43:36speachyso, it looks like an explicit HAVE_MULTIVOLUME in the presence of HAVE_MULTIDRIVE has a meaning after all −− it enables support for up to 4 volumes per disk.
13:45:31speachyso I have two choices −− revert the changes to the Creative Zen configurations to re-enable that quirk, OR make it so that all targets with MULTIDRIVE get that 4-per-disk thing too.
13:46:40speachyI good argument can be made either way. Personally I think that anything with removable storage should support the full 4 partitions/volumes per drive.
13:48:56speachycode size in the main binary goes up by ~100 bytes on the handful of ARM targets I rebuilt, and ~250 bytes on the MIPS. (Interestingly, the zen x-fi saw a 64 byte bump, vs the 6.5KB bump on the build page..)
13:50:37speachyoh, I see that number incldes RAM. nm.

17:38:03_BilgusI'm still not sure why cereal_eater thinks code changes in rb would affect his OF or am I missing something about the cowond2?
17:41:01speachyI think what's going on is that he's relying on rockbox only picking up one partition, so the partition with his OF is completely ignored.
17:42:06speachymeanwhile I need to decide what to do about my patch changing the configs on the Creative Zens
17:42:46speachyie restore their old behavior (so only they see all partitions on all drives) or enable full multivolume for all multidrive targets.
17:43:44speachyIMO the latter is the better choice.
17:43:47_BilgusIIRC the zen has an incompatible partition I don't remember the specifics
17:44:40_Bilgusits like the OF is something funky that rb doesn't like or the otherway around
17:45:32 Join IncognitoMan [0] (~Incognito@unaffiliated/incognitoman)
17:45:44speachyWell, the way it was before I committed, rockbox would see all the partitions. That is a unique setup for the Zen, and the X-Fis.
17:45:55_BilgusRockbox and Creative OS do not use the same file system so one cannot use both at the same time. In order to run Rockbox, you will need to reformat the internal storage as FAT. If you want to restore the Creative OS, you will need to reformat it using the recovery mode. It is strongly advised to put music on the SD card since the internal storage handling might change in the future and require formatting once again
17:46:10_Bilgusso I'd say it doesn't really matter
17:47:12_Bilgushonestly how important is multi partitions to the normal user?
17:47:50_BilgusFat32 supports what like ~2Tb
17:48:25speachyprobably not very.
17:48:59speachysince one would have to go out of their way to format an SD card with multiple partitions
17:49:04_Bilguspersonally I'd say chuck the multi partition in favor of code savings and make it easy enough to enable
17:50:00_Bilgusanyone savy enough to make multi partitions is savy enough to make a multi part build too
17:51:06_Bilgusthough it could be argued that you might want to see multiple partitions say from an android card or raspi card but again how likely?
17:51:24speachymost of the random SD cards I have lying around are multi-partitioned due to Linux boots
17:51:40speachythat's how I discovered this um, quirk. :)
17:51:46_Bilgusbut others might feel otherwise thats what sucks about making decisions (in a vacuum too)
17:52:23_Bilgusstill do you want to be mucking with that partition in your DAP?
17:52:25speachypersonally I think it's worth enabling across the board, as the only real argument against it is code/ram.
17:53:10speachyit concerns me that the MULTIDRIVE && !MULTIVOLUME code has somewhat bitrotted too.
17:53:25_BilgusIt doesn't really matter from the code side ram OTOH
17:54:04speachyRAM is more concerning. code size is under 100 bytes.
17:54:36_Bilgusnow 5k of ram from 8-64 mb is nothing but 5k from 1mb might be
17:55:00_Bilgushow many targets are multi volume and 1mb ram?
17:55:11_BilgusI'd say 1
17:55:38_Bilgusand its probably HWcodec which we want to end support for anyways
17:56:43speachyThere are no MULTIVOLUME targets other than the Creative bricks.
17:57:38_Bilgusmaybe if __builtin gets github access he can branch off the HWCodecs ;)
