Hi folks!
I'm writing an application running on a COBRA5329 board from senTec,
under uClinux.
I've experienced a problem on the mmc interface. I try to explain
briefly what the problem is...
These are the steps to reproduce the problem:
1. boot linux on the board
2. insert an mmc in the mmc slot
3. mount with the instruction "mount -t vfat /dev/mmcblk0p1 /mnt/mmc"
4. write a file to the mmc: cp /mnt/device1/file /mnt/mmc/
5. after finishing the copy (when the prompt became available), I try to
unmount: umount mmc.
At this point, the mmc interface starts to write the file on the mmc
card. I experienced that it takes about 45 minutes
to write a 2 MB file. It's not possible!
I think it could be the mmc driver... Anyone did experience a similar
problem?
How about solving it? If you need some more information, tell me!
Thank you very much!
Cheers
Alessandro
