Amontec Settings for netX500

The following config file works for a standard "Amontec JTagkey Tiny" with a netX500 board. It was tested on Linux with OpenOcd Snapshot 2007-07-31. Details like flash and optimized speed are still missing.

netx500.cfg file:

telnet_port 4444
gdb_port 3333

#interface
interface ft2232
ft2232_device_desc "Amontec JTAGkey A"
ft2232_layout "jtagkey"

jtag_speed 1

#reset_config trst_and_srst|trst_only|srst_only srst_pulls_trst|trst_pulls_srst|combined

#target configuration

#This file contains the board specific settings like the SDRam Parameters.

nxeb500hmi.init file:

#
# halt target

Try the Telnet interface to use OpenOcd without a GDB frontend:

telnet 127.0.0.1 4444
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
Open On-Chip Debugger
>

Please note: the numer "4444" is the "telnet_port" setting from the config above. If you change the number in your config file, change it in the telnet command too.

Make sure that the target is halted:

> halt
requesting target halt...
target already halted

Display some memory area:

> mdw 0
0x00000000: ea080001
