Hello All,

I have been trying to port eCos to a custom board based on MPC860. I 
copied the
target mbx in powerpc directory and made the necessary changes. In mbx, 
there is
an option called CYGHWR_HAL_POWERPC_MBX_BOOT_32BIT_FLASH to boot from 
32bit flash.
Our board uses Intel 28F320J5 chip arranged as 2M x 16bit memory. Any 
idea how
I need to reflect in the CDL file?

Also can somebody tell what is the difference between booting from ROM and
booting from FLASH.

Thanks in advance.
