Mounting/Accessing SD-Card on BBB

Hi,
I have a new BBB now, but the problem still persists.
So my guess about the broken SD Card slot, causing the problem, was wrong.
The other thing is that I am not always able to recreate the problem.
Sometimes rtems freezes on the open call for the file on the SD.
And when it passes that line, my program fails using mmap on the returned
file descriptor.
Best,
Nils
