Re: [U-Boot-Users] Unable to erase or write into flash

Hi,

2008/7/3 navin karnam navin.karnam@gmail.com:

Hi all,

I ported u-boot-1.3.3 on board, when boot the board iam getting messagesas below.

What do you use archtechture?

<snip>

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.

I think you failed flash protect off. Please check protect infomation by flinfo command after protect off. When protection is not excluded, setting of Flash may be wrong.

So how do i erase or write into flash, do i need to write my code which should do erase and writting into flash? or The code in u-boot is sufficient to that?

Best regards, Nobuhiro
