Redboot bootloader in ECos Source

[RRC]

Dear All,

I am having a RDC 3210 processor based board having 4MB flash
memory.On that board i am able to port redboot.bin image.Due a more
size of application(> 4 MB),i have to replace my f;ash with 8 MB
flash.

Now when i am again trying to port a redboot.bin image on that
board,it is ported but it is not booting. Even i am using the flash
IDS of 8MB flash.

I am not getting what is the problem,why it is happening? Any body is
having ideas.Please guide me for that.

Regards,
Ravi Chobey
