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 ??
