Accessing the internal ROMS
I've now managed to read data from 2 of the 3 internal Flash ROMS
This is done by using the Memory windows to map the ROMS into CPU address space.
The Intel 2M byte is connected to ROMCS1 and the 4M byte Toshiba is connected to ROMCS2
The 256Kbyte Atmel is connected to ROMCS0
Update: I have now programmed Alios into the Atmel Flash so now the system starts to boot from internal ROM! Now need to burn the kernel and initrd images into the intel flash and boot it.
I've sucessfully read the intel flash using the linux mtd subsystem, but as yet i can't program it.
I think I need to write some software to program it (similar to the wrflash prog supplied with alios).
