Hi *,
I performed the automated tests on the ML605. 64 of 65 tests succeeded, but one
test failed (mutex_test_posix).
Thus, I run the failed test some more times, in total 7 times.
- 3 runs:
went fine
- 3 runs:
the mutex was not locked in-between by the hw thread 1 of 10 times
- 1 run:
the mutex was not locked in-between by the hw thread 2 of 10 times
The debug output of the last run with 2 unsuccessful mutex_lock's is attached.
Interestingly, the delegate receives the command to lock a mutex before the
mutex is locked by the software, which should not happen. I could not reproduce
this error for the ecos API, which is a bit odd.
It would be interesting to know, if anyone can reproduce this failure.
Cheers,
Markus
