我载入了光盘上带的u-boot.bin。然后想用u-boot自己写入到flash中去。
bfin> loady

我查了下S29AL016D70有保护功能。
Sector Protection features
— A hardware method of locking a sector to prevent any
program or erase operations within that sector
— Sectors can be locked in-system or via programming
equipment
— Temporary Sector Unprotect feature allows code
changes in previously locked sectors
请教一下如何能让u-boot能烧写该flash呢？
谢谢！
