2008-06-24 16:29:28 Formatted SD card in windows, not recognised in uClinux.
blue hash (UNITED STATES)
On uClinux- 2008r1rc8, an SD card formatted in Windows( FAT, default allocation size) in not mountable in uClinux
( mount -t vfat /dev/spi_mmc /mnt )
However, if the same card is formatted with mkfs.vfat /dev/spi_mmc, the card mounts and works flawlessly.
The following flavors were tested, and all exhibit the same behaviour.
Sandisk 2GB, 1GB, 32MB, Kingston 1GB, Cannon 16MB
Has anyone noticed this? Is there an option or step being missed out?

`mkfs.vfat` does not create 32bit FAT's by default. you need to specify the -F option when running it. try formatting it with the right flag and see if you can still mount it under Linux.

Mount /dev/spi_mmc1, the first partition on the SD Card, not /dev/spi_mmc, the SD Card itself.
