RE: Is load_flash_config() necessary to redboot? I gotproblem when include load_flash_config(). thanks (more detail)


I am really sorry to disturb you. just let you know some more detail about
the problem I memtioned in the previous post.  when I connect my EPXA1 board
to hyperterminal and I can read the flash memory without any problem by
using ( x -b <location> [-l <length>] [-s] [-1|2|4]) by whenever I tried to
perform a write to the flash memory by using: "fis init" --> error message:
Error erasing FIS directory at 0x407f0000: Device/region is write-protected.
I check the MMU of ARM and make sure this region is set to RW but why I get
this error message, is there anywhere I need to set the flash memory
package? (platform EPXA1, flash memory Intel 28F320C3) Thanks a lot

This probably means that your FLASH initialization code is failing.

I'd just build a RedBoot without FLASH support and get the
FLASH code working separately.
