Data abort on Sansa Clip+ with latest daily build

(1/14) > >>

Carlo:
After updating Rockbox on my Sansa Clip+ to the 20230208 daily build I'm frequently experiencing "Data abort" errors when switching tracks or fast forwarding. They started to happen right after updating from a last december build. A sample of the error summary:

Data abort at 30063908
FSR 0x8
(domain 0, fault 8)
address 0x57ee557a
pc:30063908
sp:300d47a8
bt end

The MP3 files I'm listening to have been transferred on the Clip+ several months ago, so no recent additions, and the error manifest itself on average after 15 minutes, sometimes just after two or three minutes from booting. It cannot be reproduced, but it's triggered by switching tracks and by fast forward/reverse. Daily build from today shows the same behavior.

I've performed a r/w test on the internal memory and there are no reported issues.

Any suggestion about how to further diagnose and solve the issue? Thanks.

Edit: it seems it could be related to this bug report, https://www.rockbox.org/tracker/task/13388 . I tried to register on the bug tracker but I receive the error "Fatal error: Array and string offset access syntax with curly braces is no longer supported in /home/rockbox/flyspray/vendor/dapphp/securimage/securimage.php on line 2209".

Edit 2: it happens with the build from 20230113 too, so the bug was introduced earlier.

I have a clip+ as well and I can't repro this so far

if you want to give me the dataabort on this build we can try to trace it
I've included the .map file which should show us where the program counter is pointing

https://www.mediafire.com/file/sxd4vdznpuj8f0c/ClipPlus_3bb75e0039-230213_rockbox-full.zip/file

be sure to rename your old .rockbox folder and do a clean 'install'

it doesn't mean there is or isn't an issue with your sd card though but i'd try a different one anyway

Carlo:
It's unlikely that's an hardware issue, as I've compiled a build from 20221230 and it seems fine so far. I'll give your build a try and report back.

Carlo:
The error showed up again when using your build, this is the data:

Data abort at 30062974
FSR 0x8
(domain 0, fault 8 )
address 0xfffffef4
pc:30062974
sp:300d4740

It happened right after booting and switching no more than 6 or 7 tracks. A second one, after a few minutes:

Data abort at 30062318
FSR 0x8
(domain 0, fault 8 )
address 0xac5fdf74
pc:30062318
sp:300d4740
bt end

It seems the only common address between the last two crashes is the stack pointer one. A third one, also happened while cycling through the same directory as the other two crashes:

Data abort at 30063908
FSR 0x8
(domain 0, fault 8 )
address: 0x55555561
pc:30063908
sp:300d47a8
bt end

Bilgus:
The first two are in the font system and the third appears to be in LCD init_viewport are you using any themes or is it a bone stock install? Also do the songs it crashes on crash everytime or just randomly? any special chars in those filenames ETC?
