Results (v12):
1st (var. 1) Clip+
XM playback - crashes at 85 during load into dc_write_callback
86 works OK
Other formats (512k Opus and FLAC) crash at 85, but later, at about 2 mins into track
No reinits so far (0,0,0,0) on 86

2nd (var. 1) Clip+
Plays XM at 84, Opus/FLAC fails up until 87 with either dc_write_callback or:

Upon restart (and reset to 90), internal flash reinit on 6. May need more than 90 for stable operation.

3rd (var. 1) Clip+
At 82 no panic, but couldn't load XM (returned to menu) and logged
42 internal flash reinits
3 retry data
Unstable until 88, but at that level no reinits.

Should I test more Clips?

johnb:
Reporting back on the clip+ variant 0:
It has run now for more than 12h @ 76, stats still at 0,0,0,0!

I then switched to 75. The display starts to flicker slightly (too low refresh rate?), but it is running now for 80min stats still @ 0,0,0,0.

What's the format of your files?

johnb:
My interactive tests: flac, mp3 320kbit, opus 128kbit, some aac 128kbit.
The long playlist is mp3.

asymsucon:
Could you try these in spare time?

Both may take a while to load (30-90 seconds)
