[avr-chat] Can't program fuse bytes on USBKey via avarice.

[Andy Warner]

I posted this question a while back to the avarice-users list, to
deafening silence. I'm reposting here in the hope of more (any)
feedback:

My setup is a Fedora 8 host, running avarice, talking
to a stock USBKey via a MKII JTAGICE.

I am having problems programming fuse bytes on an
AT90USB1287 (on a stock USBKey) using avarice
and a usb-connected JTAG MKII.

Simple stuff like enabling CLKO doesn't stick.

I have not had problems programming fuse
bytes on other parts, but this is my first attempt
to program a USBKey with anything other than
dfu-programmer.

Below are read-write-read sequences (and
avarice, honestly does report that there was
some kind of problem.)

Below that is the debug output from the -W
command - which I don't know enough (yet) to
really parse.

Does this sound familiar to any other avarice users
out there ?
