We are using openocd with no problems with a ADuc7020 and ADuc7021
(different boards) but when we try to flash a board with the 7022 we run
into problems.
The debugger uses an RDI probe and we can program with it fine, we can also
verify the image (ihex) with openocd.
When we try to erase and reprogram it we get:

Here is my burn script

The Verify script is the same with the Erase and Flash Write commented out
Any ideas? Anyone work with the 7022 before?
