Far as I can tell v1.3.4 is from Sept this year. Is it older
than that?

I'm sorry I should have done a little more poking about before I
posted that. I put fw_env.config in /etc and changed the entry
to and at least
/dev/mtd1 0xe000 0x2000 0x2000
#/dev/mtd1 0xe000 0x2000 0x2000
Then created device nodes.
mknod /dev/mtd0 c 90 0
mknod /dev/mtd1 c 90 1
After that fw_printenv works. However fw_setenv returns an error.
# ./fw_setenv beets are_good
Can't open /dev/mtd1: Permission denied
Error: can't write fw_env to flash
It's probably something stupid on my part. But at least I got this
far.
Would using the latest tree be better? It appears at least that
make at91rm9200dk_config
make env
doesn't work because fw_printenv needs some kernel headers to
build correctly.
