Does this mean you have two different flash devices in the system?

If so you probably need to use the flash_v2 branch in the eCos CVS
repository.

hi !

Maybe this helps, i use flash_v2 branche to detect if i have a second flash 
device but the main detection is in HAL code in asm, because i set up mmu 
there.

But maybe it helps you:
https://dev.contec.at/dev/micro/micro9/LINUX/trunk/bootloader/ecos/patches/ecos/packages/devs/flash/arm/micro9/current/src/arm_micro9_l_flash_v2.c.diff

I will also have the same problem like you in the future to detect if i have 2 
x 16 bit device in parallel on 32 bit or 2 or 1 devices x 16 bit in 
serial(2devices). Huh a lot of asm work.... to set up mmu in asm
