Sansa Fuze+

[pamaury]

The pin clearly affects several things. I affects the OF when changing the SD card for example. But it also shutdowns some hardware, I'm pretty sure of it. In any case there is absolutely no risk.
The fix prevents blitting outside the screen but as I said I still have no idea for the crt effect (please read my post).
I also managed to make the radio work but it requires some changes in our radio code (I don't want to commit what would otherwise be a hack).
I did not manage the WPS screen spotted by megal0maniac so I can only hope it was something else (file system corruption ?).

OK. I did read your post but didn't quite understand it. I'll chkdsk my MP3 player since I had the WPS issue too.

Hi, i'm using daily build ac4d648-121201, and i get the same screen issue milonga reported.  I assume it's related to the text scrolling.  Because everytime i play a song with a *long* info string, for example a long title, the text starts scrolling and after a couple of seconds i can see the same screen issue as milonga. Controls don't respond anymore but the music keeps playing.

WPS issue can be reproduced without fail with track names long enough to cause scrolling. Didn't try any particularly long filenames last time.

Will fiddle more tomorrow and record a sample clip.
Does anyone else experience this at times?

I'm using 0f02da2-120201 and I can't confirm this sound bug.

nevertheless I have this strange display behaviour too

EDIT: most of my files are 320cbr and 16bit flac + a few 24bit flac

[pamaury]

Indeed, I can reproduce it with long names, thanks for noticing. That should help me hunt the bug !

[megal0maniac]

The WPS issue also presents itself when the track coming up has a long name.

Garbage audio
This is what I have.
For reference sake, the song is called Austere by The Joy Formidable.
There is no pitch change from the original.

To reproduce this issue, I play any of the songs from this album. The files themselves are fine and play everywhere else. (including Rockbox on my Clip+) The tracks are MP3 VBR, ranging from 170 - 200 kbps.

The strange thing, is that after you play one of these files, the phenomenon occurs with every other mp3 file you play afterwards.
The only way to fix it is to restart a couple of times (shut down properly, then turn back on) or I've found that it stops when playing a FLAC file.

I have gotten these "problem files" to play correctly on my Fuze+, but I'm not sure how.
This has been an issue since a build which was current in Early Jan.

Also, sometimes when playing FLAC, the player suddenly freezes.

Unfun

EDIT: Also, that spike on the left channel as the track starts is non existent in the file.

[pamaury]

I think I have fixed the WPS issue. Please test and report back. I will try to reproduce the sound issue but I haven't run into it so far.
Is it consistently reproducable ? Can you provide a file for us to test ?

[megal0maniac]

It seems to be, just by playing the file. Or any of the files from the album.
I just haven't been able to find out exactly how to make it go away.

I'm busy uploading a file, it lives at http://atinyhedgehog.za.net/03-the_joy_formidable-austere.mp3
Left the filename intact just to be safe. Haven't had much time to play around.

What was wrong?

[pamaury]

The bug is briefly explained in the commit message: I used the data co-processor to copy some pixels but my implementation yields during the copy instead of busy waiting. And during that yield, another screen update might occur resulting in some registers of the lcd being changed before sending the data to the lcd. One solution could be to use a mutex but I preferred to simply replace the use of the co-processor by a call to memcpy.

I got an error compiling the bootloader:

~/project/rockbox/firmware/target/arm/imx233/sansa-fuzeplus/lcd-fuzeplus.c: In function 'lcd_init_device':
~/project/rockbox/firmware/target/arm/imx233/sansa-fuzeplus/lcd-fuzeplus.c:388: error: 'lcd_on' undeclared (first use in this function)


Had a look in the code, 'lcd_on' is defined as:

#ifdef HAVE_LCD_ENABLE
bool lcd_on; /* framebuffer-imx233.c */
#endif


But I cannot find anywhere in the code that defines HAVE_LCD_ENABLE. Is this set by the configure script?

EDIT:

Ignore the above post, I updated my source tree and the problem is gone now.

[pamaury]

The bootloader built has been fixed. But you normally don't need to build the bootloader, there is already a released version on our server.

Thanks pamaury,

Everything working OK now.

By chance today I managed to get the weird audio bug that megal0maniac described (with the exact same file). But it was by chance: I forgot to shutdown my player and after some time I realized it was still playing the audio output was exactly like yours. I'll try to add some audio debug screen in case it happen again.

[megal0maniac]

Is there anything I can do in the way of capturing debug info when this behaviour occurs?
Something I could compare between regular and broken playback?
Have you perhaps found anything unusual about the file? (It does this with the whole album, though)
