Sascha, thank you for the prompt response.
Unfortunately the new version works only partially with my Beagle
Board (rev. C4).
I tested commit:
46976f7 OMAP: fix compilation
- Test 1: the board is always powered.
Press RESET with the USER key pressed.
10 tests, 10 passed.
- Test 2: the board is not powered.
Turn turn it on with the USER key pressed.
Turn turn it off again at the end of the test.
10 tests, 5 passed, 5 failed.
During all of the 20 tests, barebox.bin was always the same.
I didn't recompile it.
OTOH the commit before the "reimplement in C" passes also test 2.
I hope this gives enough hints to solve the problem.
Luca
