Hi ,
You are right, flash protect was not happening properly because i was not enabled the the FLAG CFG_FLASH_PROTECTION. Now it is happening after enabling it.
Thanks and Regards, Naveen.

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
