AXIOM CME555 Redboot FLASH Memory Read Problems

- Bcc:
Hi All,
I have questions regarding problems with Redboot crashing on a CME-555
platform when using FLASH memory support. The symptoms appear to be the same
as the problem described by Miguel Vega in his posts, but I haven?t found
any follow-up posts from him describing whether he found any solution(s).
I?ve modified am29xxxxx_parts.inl to include the AM29LV400 device and
Redboot successfully recognizes the device ID and completes the FLASH
initialization.
However, it crashes when memcpy() is used to copy the Redboot configuration
data in load_flash_config() located in flash.c.
I?ve used gdb to investigate this crash and have found that the problem
always occurs on a read from FLASH. If I try to examine the memory location
with gdb, I receive the message ?Cannot access at address 0x880000?. Yet, a
read of 0x880001 returns the proper data.
Has anyone else come across this, and is there a solution? Any help would be
greatly appreciated.
Mike Pashea
