[U-Boot-Users] Re: Help: Device protect error

[王 振]

hi wd,

  I think I hadn't explained my situation clearly in my last post. 
  I did copy board/pleb2/flash.c as my board's flash.c because this file 
provided flash driver for Intel 28F320C3B flash memory and created a 
configuration header file for my board. I don't know whether this could be 
called 'adapt the flash driver' but in the end I could see u-boot's output 
in minicom and the flash memory was correctly recognized. Now the problem 
is that 'erase' command doesn't work, I do need some precious hints about 
how to solve it. 
  Besides, I wonder if cfi_flash.c can drive Intel 28F320C3B on my board 
because there is no CFI on my board.

Best regard,

Zhen Wang
