NAND Problem u-boo

Hi.

We are working on OMAP-L138 custom board. We have some problems with all the NAND commands from u-boot.

The nand seems to be correctly identified. but reads and dumps fails with error, write don't seem to be properly:

We are using latest mcsdk_1_01_00_02

Here is my memory contents after fatload command:

U-Boot > md 0xc0700000

When i issue 'nand erase 0x20000 0x80000' then 'nand write.trimffs 0xc0700000 0x20000 0x80000' i get '524288 bytes written OK'

Then when i issue 'nand dump 0x20000' i get:
