OpenOCD

Hi,

exists at Hilscher an simple example using OpenOCD and netX100 - for example blinking a led at a EvaBoard like NXSB100?

I found a configuration example for OpenOCD and netX100 in internet. Maybee this example have its origin at Hilscher and there exists also some examples at Hilscher.

best regards
Martin

OpenOCD is a JTAG interface to controllers (e.g. ARM based) using FTDI chips or some other JTAG Hardware.

It is not responsible for blinking LED's etc. You will need to download ARM/netX Software (.elf file) via JTAG and let it run on the Board. (As you are used to, when using HiTop). If you want to blink LEDs via JTAG you will need to search the OpenOCD command interface documentation for commands like mdw, mww, etc.

There is no example available, but there are many sites on the net providing information about OpenOCD with sample scripts.

I can only provide you a sample script for a NXHX-500RE without warranty and support:

tcl_port 6666
telnet_port 4444
gdb_port 3333

This script will basically connect to a NXHX500-RE Board using the On-Board JTAG. How to download and Debug your application is up to you using the OpenOCD command interface (telnet) and/or an external GDB Debugger (e.g. Insight).

Please keep in mind that, due to the variety of debugging software using GDB interface and different JTAG hardware interfaces, it is not possible to support OpenOCD in general and every possible detail.

Here a list of public sites (no support from Hilscher) with information about configuring OpenOCD and using the telnet interface:
OpenOCD Documentation
OpenOCD Intro
Eclipse sample
