Hello all!
I have a question about mdev. I hope someone can offer an idea.
I have the mmc_spi.c driver build into my linux kernel. When I first
boot, and a mmc card is installed, it is detected by mdev and I get:
/mnt # ls /dev/mmc* -la
brw-rw---- 1 root disk 179, 0 Oct 30 09:10 /dev/mmcblk0
brw-rw---- 1 root disk 179, 1 Oct 30 09:10 /dev/mmcblk0p1
At this point I can mount it and everything works great.
But, if I eject the card and re-insert it I get:
/mnt # ls /dev/mmc* -la
crw-rw---- 1 root disk 179, 8 Oct 30 09:23 /dev/mmcblk1
crw-rw---- 1 root disk 179, 9 Oct 30 09:23 /dev/mmcblk1p1
Now I can no longer mount the card since it is a character device.
Any ideas why it shows up as a block device at boot, then as a character
device after that?
Thanks,
Hartley
