Hi all,
I ported u-boot-1.3.3 on board, when boot the board iam getting messagesas below. ------------------------------------------------------------------------------------------- U-Boot 1.3.3 (Jul 3 2008 - 10:17:59)
DRAM: 64 MB Flash: 64 MB *** Warning - bad CRC, using default environment
In: serial Out: serial Err: serial Hit any key to stop autoboot: 0 -----------------------------------------------------------------------------------------------------------
But when try erasing flash : #erase all Erase Flash Bank # 1 - Warning: 259 protected sectors will not be erased! done
So i enabled the flash for writing using: #protect off all Un-Protect Flash Bank # 1
After that also i am unable erase the flash: #erase all --------------------------------------------------- Flash erase error at address 680000 Block Erase Error. Block locked.
