Hi

This may or may not be off topic ... just let me know.

I purchased a 3Com Audrey in the hopes to get Linux on it. I'm currently looking at LinuxBIOS (and other possibilities). It has a CFI Flash on it and am curious how to program the flash in-circuit.

In reading your How-To i noted the JFFS2 for embedded systems. I curious about the following:
1. In-circuit programming of CFI flashes .. is this feasible? does a utility already exist?
2. How do I get the JFFS2 and Linux on this device? ... maybe I need to read the How-TO a little more ...

Thanks in advance for your input

1. In-circuit programming of CFI flashes .. is this feasible? does a utility already exist?

A commonly used trick on StrongARM SA11x0 platforms is to program the flash from the CPU JTAG interface (JTAG is a debugging interface). The utility "jflash" exists for that, it bit-bangs the JTAG protocol on the parallel port. You can get it (for the Intel Assabet board) at ftp://ftp.arm.linux.org.uk/pub/linux/arm/people/nico/Assabet-Jflash-v1.2-1.tgz No idea if it will be useful for you.
