A couple of people from Motorola have indicated, for the past year or so, an interest in providing a TFTP monitor for the FADS board. When they have asked what to do, I said make sure it is GPL and send it to me for posting on a server somewhere (like ppc.kernel.org). I have never heard a reply. I am sure you could put something together from some of the netboot code that is around. My approach is to actually port a Linux kernel to the 8xx board, which is pretty easy these days for just the minimal network support, then slightly "customize" it (so it doesn't use _all_ of memory) and flash is using S-record download or BDM tools. I then just use the Linux kernel with a TFTP application to do the job. Just mmap() the unused memory for loading a new image, and modify the reboot to call a specific address rather than return to rom. -- Dan ** Sent via the linuxppc-dev mail list.
