Hi Mr. Nelson,
Problem in short
I changed partitioning command but with help,
Here is my sfdisk commad,
#Partition
drive
sfdisk --force --in-order --Linux ${DRIVE} -uM
<<-__EOF__
1,32,C,*
,200,L
,200,L
,,E
,100,L
,60,L
,200,L
,1269,L
,,,-
__EOF__
After above command i sync and flush buffers using blockdev command.
and then run "mdev -s" but
I get following output,
*sfdisk: ERROR: sector 184348 does not have an msdos signature*
sfdisk: /dev/mmcblk0: unrecognized partition table type
Old situation:
sfdisk: No partitions found
New situation:

Re-reading the partition table ...
If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)

Can we conclude that from mmc driverside there is problem.
Do you doubt mdev ??
Can network boot affect ? I am booting from network to update eMMC.
Thank you,
