Same error as before

saratoga:
Here is a build with the unboosted voltage register increased from 22 to 25:

By the way, if you have a smartphone could you load a working build without voltage scaling, go to System -> Debug -> View IO Ports and then hit down until you see the screen with "CVDD2" on it and take a picture?  I'm curious if your player has similar voltages as mine does. 

qorx:
That seems to fix it as it runs without any error anymore.
The "CVDD2" value fluctuates between 2705 and 2720

saratoga:
Can you try this one as well?

Your voltages look identical to mine at least.

Edit:  If that fails, here is 24:

Lower will use less power, so its worth finding the minimum. 

qorx:
23-voltage is running ok, it gives an estimated 26h of battery :) Thank you!
I've tried 24 as well and it displayed 25h...

If the voltages are identical to yours, what may be causing the error on mine with a lower value? Any idea?
