No, I don't believe so. (The flash was programmed with one of Atmel's ASF
(Atmel Software Framework) example application.)

Thanks, I managed to apply these patches to my local build and rebuilt via
"make; sudo make install".

I'm not sure about SRST; I'll have to see if I can locate a schematic for
Atmel's SAMD20 Xplained Pro evaluation board (the one I'm using at the moment.)
Regarding "reset_config srst_only", I found the following inside of
at91samdXX.cfg:
reset_config srst_gates_jtag
I changed this to read "reset_config srst_only" and tried running openocd
again, without successfully connecting.
Do I have to change "cortex_m reset_config" as well to use "srst_only"?
