Other Parts Discussed in Thread: EK-TM4C123GXL, TM4C123GH6PM

Recently I received my Tiva Launch Pad. I use Linux only, so wanted to try its programming/ debugging using OpenOCD+arm-gdb.

I created the following board config file in the directory /usr/local/share/openocd/scripts/board/

ek-tm4c123gxl.cfg:

----------------------------------------------------

#
# TI Tiva Launchpad ek-tm4c123gxl Evaluation Kits
#
# http://www.ti.com/tool/ek-tm4c123gxl
#

#
# NOTE: using the bundled ICDI interface is optional!
# This interface is not ftdi based as previous boards were
#
source [find interface/ti-icdi.cfg]

set WORKAREASIZE 0x8000
set CHIPNAME tm4c123gh6pm
source [find target/stellaris_icdi.cfg]
------------------------------------------------------------------

and it works fine. I have tested with project0 and hello

Thanks for the information and the config file. The ICDI interface is identical to Tiva LaunchPad so it was expected to work but have not personally tried it yet. Always good to get independent confirmation

Glad to hear that Tiva LaunchPads are being well used in the community.

Thanks also to Spen and others with OpenOCD and their community for doing a significant amount of work on openOCD to get it operational with Stellaris LaunchPad.

Hi,

did you write some config files to flash / debug an Tiva via the onboard JTAG interface?

Sorry, no. I do not have JTAG equipment and at present use only ICDI interface.
