Sansa C250 Down button is always pressed. Functions fine with OF.

(1/1)

dodddummy:
I have a sansa c250 v1.  Just installed RB.  The issue I'm having is that it's behaving as if the down button is always pressed.  OF functions correctly so I don't think it's a hardware issue.  I've tried several version of RB and all behave the same.  I did notice that if I jam my thumbnail in between the button and the case hard, the the cursor will move up.  But when I release it, it goes down again.

OF is 01.01.01P

Is this a known issue?  My searches didn't find anything.

saratoga:
The debug menu on the c200v1 should (i think) let you see the GPIO pins in real time.  Can you get to it (may not be possible given the keymap)?  If so, I'm curious what button (if any) changes when you press the down button.

lebellium:
Just tried the latest build available in Rockbox Utility (bfd04df) on my C200v1 and I don't have this issue.

In the debug menu->view I/0 ports>GPIO INPUT VAL, when I press "down",  H: goes from 21 to 20.
