Hi All,

Only with 256MB partition size it is not working.

When you reduce the size do the writes to the fourth partition work or only to
the first three partitions?

Yes its working fine for all partitions.With MTD Utility I have not tried.

We had combination of 300MB 300MB 300MB and rest is fourth partition (of 1GB NAND). It is working fine, read/write on all partitions done successfully.

Was this issue is faced by anyone or this is the first time I am getting?

Thanks & regards,
Saquib

When you reduce the size do the writes to the fourth partition work or only to

If you read/write with the mtd tools what happens?
