Booting from serial flash?
Hi everyone,
I was wondering if anyone can help me on this matter: does the U-boot support loading solely from serial flash or nand flash (i.e. no other flash is available)? If so, which of the boards support that. I've been digging into the U-Boot files and I found support for compact flash but it exists along with another flash memory, where as I need a bootloader running with only compact flash.
Thanks,
Hoda

You are asking the wrong question. It is not U-Boot that can or can not support such a boot mode, but the processor you are using.

Again the wrong questions. It is not the board that maters, but the processor.

I don't know of any processor that can boot from CompactFlash without using a primary bootstrap loader in some other boot device like standard NOR flash.
