So, I just posted how I got the Jtagkey setup with openocd. The problem I’m having now is that I can’t halt the processor. I can telnet into 4444 and run commands like version, which returns “Open On-Chip Debugger 1.0 (2008-10-20-14:03) svn:1083” and poll, which returns “target state: running”. I know it is connected to something because if I disconnect it from the processor before I start openocd then I get errors, and when it is connected when I start I get:
jtag_speed: 3
Info: JTAG device found: 0x15b0203f (Manufacturer: 0x01f, Part: 0x5b02, Version: 0x1)
Error: unknown EmbeddedICE version (comms ctrl: 0x00000000)
My config file is:
#daemon configuration
telnet_port 4444
gdb_port 3333
#interface
interface ft2232
ft2232_device_desc "Amontec JTAGkey"
ft2232_layout jtagkey

Is there something wrong with my config file? Is there a standard config file for the at91rm9200?
thanks,
Paul
