Where do you set this up? If I want to use partitions, where do I put the info on how it is partitioned?
I modified the kernel .config and it gives me the following startup messages: physmap flash device: 80000 at fff00000 CFI: Found no Physically mapped flash device at location zero I'll check out the MTD list. Chuck >>> <Jan.Rovins at radisys.com> 06/26/02 02:49PM >>> I agree that MTD is the way to go, but with one small change to Michael's instructions. configure MTD for char driver support, and do dd if=bootloader of=/dev/mtd0 /dev/mtd0 is a raw char device that is best to write a binary boot image to flash, /dev/mtdblock0 is a block device that is best for file system images, which can then be mounted. You can get expert advice from the MTD list: http://lists.infradead.org/mailman/listinfo/linux-mtd/ Jan "Michael Meriin" <Michael at KSWaves.com> Sent by: owner-linuxppc-embedded at lists.linuxppc.org 06/26/2002 12:17 PM To: "Chuck Partridge" <Chuck_Partridge at amx.com>, <linuxppc-embedded at lists.linuxppc.org> cc: Subject: 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 Best Regards, Michael Meriin ----- Original Message ----- From: "Chuck Partridge" <[EMAIL PROTECTED]> To: <linuxppc-embedded at lists.linuxppc.org> Sent: Wednesday, June 26, 2002 17:09 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.
