Mark - would it make sense to put something (udhcpd) in your bigdisk upgrader image to configure the network?
Maybe. But that still doesn't solve the problem of how to get the bigdisk .upgrade loaded on to a blank empeg. A better solution would be to enable/use the kernel's *built-in* IP-autoconfig feature.
What is in the bigdisk images and can they be rebuilt from source? (and maybe bblobs)
I've got them quite automated here now. Hang on for a spell, and I'll post a tree with scripts.
Tony - won't 'download' work from linux (a tiny .c program that installs a kernel image via serial at the "penguins" bootloader prompt?)
That program is only for kernels and other flash blobs, not for .upgrade files. And it still fails on some, but not all, USB serial ports as of the Linux 2.6.2x series of kernels (on the host side) -- it used to work with older kernels.
Cheers
