Re: Fwd: Mounting MMC card

Hi All,

   Here goes the output(error).

/ # dd if=/dev/mmcblk0 of=/dev/null count=100
dd: can't open '/dev/mmcblk0': No such device or address

   The /dev is has the following:

/ # ls -l /dev | grep mmc
brwxrwxrwx    1 0        0        254,   0 Jun 26  2007 mmcblk0
brwxrwxrwx    1 0        0        254,   1 Jun 26  2007 mmcblk0p0
brwxrwxrwx    1 0        0        254,   2 Jun 26  2007 mmcblk0p1
brwxrwxrwx    1 0        0        254,   3 Jun 26  2007 mmcblk0p2
brwxrwxrwx    1 0        0        254,   4 Jun 26  2007 mmcblk0p3

   So are the device nodes wrong? When i say `cat /proc/devices` it says :

/ # cat /proc/devices
Character devices:
 1 mem
 2 pty
 3 ttyp
 4 /dev/vc/0
 4 tty
 4 ttyS
 5 /dev/tty
 5 /dev/console
 5 /dev/ptmx
 7 vcs
10 misc
13 input
29 fb
90 mtd
128 ptm
136 pts

Block devices:
 1 ramdisk
 1 ramdisk
31 mtdblock
254 mmc

 So is the major number 254 is correct for MMC ??

Midhun.
