[U-Boot-Users] Locked block in StrataFlash

[llandre]

Hi all,

I experienced a problem with strataflash driver on ARM920T-based custom 
hardware. The driver has been derived from 
board/esd/cpcpi440/strataflash.c. When issuing a saveenv command, U-Boot 
randomly can't erase the block because it is locked (environment is in 
flash). We verified with JTAG debugger that status register and it 
confirmed the locked state. To unlock the block we issued manually the 
necessary commands. The function flash_real_protect is never invoked (I 
verified with JTAG debugger that it is never executed, too).
Anybody experienced similar problems?
