Re: AMD Flash Interface for updating boot flash

Just define your flash as a MTD device and then, from user space use dd
command to copy your bootloader to flash:

dd if=bootloader of=/dev/mtdblock0

Subject: AMD Flash Interface for updating boot flash

Hello all,

I have been searching the archives and I am a bit confused, so bear with

me if this is too simple a question.

I need to provide a way to update my boot flash from user space.
Our user application will download an boot flash image and save it (to a

file or a buffer), we must then write the flash.

I have seen references in the archives to Denx's drivers/char/amd_flash.c

and to MTD drivers, or I can

implement my own driver, but I'm not sure of the best (i.e. easiest and

cleanest) way.

I don't need to put a file system on the flash.  All it does is hold the

PPCBoot image.  The flash part is an AMD

29LV004B and is setup for 8 bit interface.  I am running a 2.4.17 kernel

on an 8245.

Any suggestions?

Thanks,

Chuck
