Hi Mr. Nelson,
I made some progress,
mdev was auto-mounting /dev/mmcblk0* partitions, i changed following line
in the mdev.conf file.
*#mmcblk[0-9]p+[0-9]* root:root 660 */etc/mdev/mount.sh $MDEV*
*mmcblk[0-9]p+[0-9]* root:root 660 *
But i don't understand why auto-mounting was creating problem,
Because before erasing the partition, I was checking if partition is
mounted or not and if mounted i was umounting it.
Is it right change ?
Thank you
