Error: Wacky! Unable to decode failure status

[Michael Moedt]

Hi.
I'm having trouble using the 'erase' and 'eraseall'
utilities on my flash device.  It's an AMD29LV640ML,
which supports CFI and uses command set #2.

I'm getting the error message "Wacky! Unable to decode
failure status".  See below: (with minor modifications
to make it more readable)
----------

The procedure that is being executed is in
cfi_cmdset_0002.c. (around line 1100)

Does anyone have a hunch of what it could be?

Thanks!

Mike
