[ECOS] AXIOM CME555 Redboot FLASH Memory Read Problems
Fri Aug 24 17:24:00 GMT 2007
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 havenÂt found
any follow-up posts from him describing whether he found any solution(s).
IÂve modified am29xxxxx_parts.inl to include the AM29LV400 device and
Redboot successfully recognizes the device ID and completes the FLASH
However, it crashes when memcpy() is used to copy the Redboot configuration
data in load_flash_config() located in flash.c.
IÂve 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 ÂCannot access at address 0x880000Â. Yet, a
read of 0x880001 returns the proper data.
Has anyone else come across this, and is there a solution? Any help would be
