Hi Denk,

This issue is being solved . Read and write permissions are provided only to
MAX_MTD_DEVICES partitions.Its value was set to 6 ( reason for having read
and write access for 0-5 partitions only ).On changing the MAX_MTD_DEVICES
macro value from 6 to 7.I am able to obtain the read and write permissions
for all the available flash partitions.

Thank you for the support.
Babu
