Hi all,
How do I test micro-SD in our newest kernel?
I try two SanDisk micro-SD cards. One is 128MB and Another is 512MB. The
512MB card is successful mounted file system. But 128MB card will fail.
Hiya Willie -
First most of that log is SDIO for WLAN from Sameo's patches, it's fine.
Second, the message that is worrying you is probably
[ 89.380000] VFS: Can't find a valid FAT filesystem on dev mmcblk0.
[ 89.390000] FAT: bogus number of reserved sectors
[ 89.390000] VFS: Can't find a valid FAT filesystem on dev mmcblk0.
but this is also fine. In the Windows world many Flash devices do not
have a partition table, they stick the filesystem directly to the raw
block device, ie, like it was written on /dev/sda instead of /dev/sda1
The kernel is trying first to mount "/dev/sda" (ie, /dev/mmcblk0) for
that reason and failing because there is a partition table there and not
a filesystem. Then it tries /dev/mmcblk0p1 (first partition)
and it is okay and doesn't make a message for it... you can just find it
at /media/card
If that isn't the whole problem, please send more about it.

Hi Andy,
I test the two micro-SD cards (128MB and 512MB) and I can browse the
files in both micro-SD cards. Thanks for your help.
Regards,
Willie
