AXIOM CME555 Redboot FLASH Memory Read Problems


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
