[OpenOCD-user] OpenOCD and Stellaris LM4F120

[Zbigniew <zbi...@gm...>]

Hello,
I'm trying to use OpenOCD 0.12.0 with TI Stellaris LM4F120 board (Linux
Slackware64 15.0) the following way:

openocd -f /usr/share/openocd/scripts/interface/ti-icdi.cfg -f
/usr/share/openocd/scripts/target/stellaris.cfg

It answers:

Open On-Chip Debugger 0.12.0
Licensed under GNU GPL v2
For bug reports, read
        http://openocd.org/doc/doxygen/bugs.html
Info : auto-selecting first available session transport "hla_swd". To
override use 'transport select <transport>'.
Info : The selected transport took over low-level target control. The
results might differ compared to plain JTAG/SWD
Info : Listening on port 6666 for tcl connections
Info : Listening on port 4444 for telnet connections
Info : RCLK (adaptive clock speed)
Error: mode (transport) not supported by device

The board (its "debug" connector) is connected to /dev/ttyACM0 and I have
rw rights (I also verified with minicom I can "talk" to "default"
LED-controlling app using that tty).

What do I need to do to make OpenOCD cooperate? I found two or three web
pages containing a few tips, but all they are more than 10 years old and
contain outdated info, partially not applicable to newer versions of
mentioned software, so the tips I was trying to use gave no effect.

How the present version of OpenOCD can be persuaded to talk to Stellaris
board?
