Hi,
did an additional test, that i hope can help:
- prepared a 16K ASCI pattern of 0x30,0x31,0x30,0x31.. and so
- written to mmc sd
[root@barix boot]# cat 16kpattern.hex > /dev/mmcblk0p1
[root@barix boot]# Automount: /dev/mmcblk0p1 inserted
Automount: DEVICE LOCK found quiting...
[root@barix boot]# cat /dev/mmcblk0p1
i could read out _only_ 8K of patterns bytes and then i see other fs
bytes just after.
So seems i can't write 8K blocks, seems 4K are truncated.
Regards
angelo
