I am currently working on MPC8323E-RDB Board. I have loaded u-boot and its working fine. I want to copy kernel image and root file system images into flash from RAM. I have already executed kernel image via tftp. But while copying into flash from ram it is giving error some sector is protected and can.t be write. By using protect off command i am trying to unprotect that particular sector. But it is giving again that error. I am attaching flash info text file. How can i erase that sector?
