Hello

I tried this and cannot get the JTAGKey2 to work - there are endless
errors reported when trying to load code although openocd does
initialize and see the jtag chain.

AT this link http://www.zylin.com/zy1000/openocd.pdf which appears to be
a manual for OpenOCD 0.3.0 there is mention of a JTAGKey2 layout:

"ft2232_layout name ..... 
jtagkey Amontec JTAGkey and JTAGkey-Tiny (and compatibles)
jtagkey2 Amontec JTAGkey2 (and compatibles)"

This seems to imply that there is a difference on the PCB. Is that
right?

Len

The USB manufacturer and prodcut IDs are the same for JTAGKey 1 and 2
(is that right?), so the only thing that changes is the Product string.
(I wish they'd either changed both pid _and_ desc, or neither. Just
changing one is unhelpful as it requires what seems to be a gratuitous
config change. 

Which means the openocd config changes from :
interface ft2232
ft2232_device_desc "Amontec JTAGkey"
ft2232_layout jtagkey
ft2232_vid_pid 0x0403 0xcff8

to:
interface ft2232
ft2232_device_desc "Amontec JTAGkey-2"
ft2232_layout jtagkey
ft2232_vid_pid 0x0403 0xcff8

Openocd itself shoulnd't need to change at all.
