AVRs get along quite nicely with Linux, which I primarily development on. But I’ve been hearing great things about TI’s line of inexpensive development boards and their toolchain. So I took the plunge and ordered a dev board. Well as it turns out I ordered the wrong board. Woops! Instead of the $10 MSP EXP430G2 Launchpad (featuring their MSP430 8 16bit microcontroller) development board I accidentally ordered the $13 Tiva C series TM4C123GXL Launchpad. Oh well, there are worse things than mistakenly getting an ARM dev board for a few bucks. So what’s the toolchain even like on this thing? Will I need to download some massive IDE? After some quick searching I was happy to find that building, flashing, http://chrisrm.com/howto-develop-on-the-ti-tiva-launchpad-using-linux/ 1/11 1 export PATH=$PATH:$HOME/Embedded/gccarmnoneeabi4_82014q1/bi This will only last for as long as you’re logged in however.tar. along with a few of my own notes and helpful tidbits. I’ll be working in a folder named Embedded in my home directory. Add the extracted directory’s bin folder to your user’s path.00 libusb1.9/13/2015 HowTo: Develop on the TI Tiva LaunchPad using Linux | chrisrm and debugging can all be done with command line Linux tools. 1 2 mkdir ~/Embedded cd ~/Embedded 2. 1. This step should hopefully work for both 32 and 64bit systems now (thanks Mayank!) And if you happen to be an Arch Linux user and are following along be sure to check out Vivek’s advice in the comments for further 64bit instructions. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 # For 64bit systems: sudo dpkg –addarchitecture i386 # For everybody: sudo aptget update sudo aptget install flex bison libgmp3dev libmpfrdev \ libncurses5dev libmpcdev autoconf texinfo buildessential libftdidev pythonyaml zlib1gdev libtool # For 64bit systems yet again: sudo aptget install libc6:i386 libncurses5:i386 libstdc++6:i38 # I needed these as well flashing over USB: sudo aptget install libusb1. Then extract it (including the toplevel “gccarm noneeabi…” folder) into ~/Embedded.bz2 C 4.10 Saucy Salamander. 1 tar xvf gccarmnoneeabi4_82014q220140609linux. Let’s create a working directory to hold our projects and toolchain.00dev 3. The following setup instructions were taken from the Tiva Template project and the Recursive Labs Blog. For a more permanent solution http://chrisrm. Dependencies This section only needs to be performed once to get your development computer setup. Go to the GNU Tools for ARM Embedded Processors page and download the most recent tarball for Linux. Install some dependencies using the commands below. on a computer running Ubuntu 13.com/howto-develop-on-the-ti-tiva-launchpad-using-linux/ 2/11 . and will need to be rerun each time you want to do development. We even have debugging capabilities. To do this open/create ~/. Extract the exe file to a new tivaware folder in Embedded using the commands below. The Tiva Template project has the stuff we need for compiling. Grab it from GitHub and compile the source. lm4flash will work out of the box. and place it in the tivaware mv ~/Downloads/SWTM4C2.

Compile with make 1 make 8.12573.bashrc and add the above command (at the bottom or wherever appropriate). After that unplug the board.exe when I downloaded it. and reconnect the board.9/13/2015 HowTo: Develop on the TI Tiva LaunchPad using Linux | chrisrm you can: copy the contents of gccarmnoneeabi4_82014q1/bin to one of the directories in your path (not recommended) create/modify your .
