EK-TM4C123GXL

This minimal development environment for the Texas Instruments EK-TM4C123GXL. It is intended to provide a quick way to create and compile a C project for the TI TM4C123GH6PM MCU. The CMSIS headers are copied from Energia.

Prerequisites

• The ARM GCC toolchain must be installed. The bin directory must be in your PATH.
• make must be installed on the system. Linux users: sudo apt install build-essential

Usage

The files in this repo are intended to be used as a template. Use the init.sh script to create a new project:

• init.sh /path/to/project

The /path/to/project may be absolute or relative. Move into the project directory and use make to build:

• make

Other targets like make clean are supported for convienence. A single "blink" example is provided to demonstrate application usage.

Using an External J-Link Probe

• Solder headers onto the unpopulated JTAG breakouts.
• Set the board's slider switch to "DEVICE".
• Power the board with the "DEVICE" USB
• Connect a Segger J-Link debug probe. Make the following connections:

J-Link	EK-TM4C123GXL
VTref	VBUS
TDI	TDI
TMS	TMS
TCK	TCK
RTICK	GND
TDO	TDO
RESET	RESET
GND	GND

Flash & Debug

• Flash and debug the program with the Ozone application.
• In the "New Project Wizard":
  • Device: TM4C123GH6PM
  • Target Interface: JTAG
  • Host Interface
  • Target Interface Speed: 1 MHz
  • Program File: /path/to/project/build/project.out
• Peripheral register definitions can be provided to Ozone in the optional "Peripherals" field. You will need the TM4C123GH6PM's SVD file. The file may be found in this CMSIS-SVD repository.
