TI EZ430 in Linux with IAR Kickstart

by Travis Goodspeed [travis at]
at the Extreme Measurement Communications Center
of the Oak Ridge National Laboratory

What follows are instructions for running the free version of IAR's C compiler for the MSP430 with Texas Instruments' EZ430 development tool in Linux under Wine. This will not work for Mac OS X until msp430-gdbproxy is made available for that platform. Also, this might not work with the full version of the compiler.

These instructions assume that you've installed wine, mspgcc, and msp430-gdbproxy. The assumption is also made that you've purchased the EZ430-F2013 development tool from Texas Instruments.

IAR Embedded Workbench

First, download from the EZ430-F2013 page. Unzip it to get FET_R510.exe. Running wine FET_R510.exe installs the compiler to your C: drive under wine.

Next, you must find the executable and run it.

The usage information will be valuable, but is too long to scroll through. Pipe it to a textfile for later reference. Also, make some symlinks to more easily get at include files and the documentation:

Make scripts for both the compiler and the assembler. I'm uninterested in the IDE.

wine "C:\Program Files\IAR Systems\Embedded Workbench 4.0\430\bin\a430.exe" $*

wine "C:\Program Files\IAR Systems\Embedded Workbench 4.0\430\bin\icc430.exe" $*

The compiler's options are very different from those of GCC, and you must remember (or update your script) to include the IAR include directory if you intend to use its headers. A test compile of the LED blinker from follows.

karen% icc430 -I "Z:\opt\IAR\430\inc" msp430x20x3_1.c --output blink.exe

IAR MSP430 C/C++ Compiler V4.09A/W32 [Kickstart]
Copyright 1996-2007 IAR Systems. All rights reserved.

34 bytes of CODE memory
0 bytes of DATA memory (+ 4 bytes shared)

Errors: none
Warnings: none

Now that the compiler is working, you'll need a linker. I use the following script:

opts="-f Z:\opt\IAR\430\config\lnk430F2013.xcl -Fintel-standard Z:\opt\IAR\430\LIB\CLIB\cl430f.r43 -s __program_start "
xlink="C:\Program Files\IAR Systems\Embedded Workbench 4.0\common\bin\xlink.exe"
wine "$xlink" $* $opts

msp430-objcopy aout.a43 aout.exe

The format switch, -Fintel-standard, makes the output file in the ihex format, one which msp430-objcopy can handle. This will let us program the board using msp430-gdb, so the GNU tools may be used to load the executable. Also note that you'll need to uncomment lines 76 and 77 of /opt/IAR/430/config/lnk430F2013.xcl to define the stack and heap sizes. This script is called as xlink msp430x20x3_1.r43.

The following is a functional, if inelegant, Makefile:


all: $(ALL)

msp430x20x3_1.r43: msp430x20x3_1.c
icc430 -I "Z:\opt\IAR\430\inc" msp430x20x3_1.c
msp430x20x3_1.exe: msp430x20x3_1.r43
xlink msp430x20x3_1.r43
cp aout.exe msp430x20x3_1.exe


Assuming that msp430-gdb and the USB-FET drivers have been properly installed, the GDB server can be loaded as

karen% msp430-gdbproxy msp430 --spy-bi-wire /dev/ttyUSB0

Your ~/.gdbinit file should be

msp430-gdb runs with no options. Use load foo.exe to load an executable that has been made by msp430-objcopy.

Loading section .sec2, size 0x2 lma 0xfffe
debug: MSP430_Memory(WRITE)
Start address 0xf800, load size 58
Transfer rate: 464 bits in <1>

Note that without "monitor interface spy-bi-wire" in .gdbinit and "--spy-bi-wire" to msp430-gdbproxy, load will still work but many debugging functions will not. Also note that the run command seems to have issues with spy-bi-wire; use continue instead.

You should now be able to play around with the MSP430. Grab the msp430f2013 datasheet and family guide if you'll be doing anything fancy.

Note that you'll probably want to use the '-e' switch when building complicated scripts to prevent the following error:
keyword "__interrupt" used with IAR extended language disabled

Ansis Atteka said...

Thanks for great tutorial!

1)Is this is applicable to EZ430-RF2500 to get it working under Linux?
2)What kind of driver did you use? The one which comes with linux?

Travis Goodspeed said...


The USB/serial chip in the RF2500 kit is not compatible with Linux. To make it work, you need to remove the CAT24C EEPROM and reflash the MSP430 with firmware from a blue/green EZ430F2013 kit.

Also note that the EZ430F2013 and MSP430 FET UIF devices only work with considerable difficulty in Linux. In Ubuntu 9.04, for example, I need to boot kernel 2.6.27 as 2.6.28 has broken TUSB3410 support.

1. I want to ask same questions as Ansis said,
2. I don't know how to remove the CAT24C EEPROM and reflash the MSP430 with firmware from a blue/green EZ430F2013 kit.

Please please help me to work with
EZ430-RF2500 in Linux comfortably.

Thanks for the great HOW-TO. I used it to get the IAR Embedded Workbench 6.0 Kickstart working from the command line in Debian Squeeze. (I built and used wine-1.3.34 because the version in the repo is ancient and does not work with the current version of IAR.)

FYI, the GUI is working, too. You need to symbolic link the correct tty (/dev/ttyUSB0 on my machine) to com1: in wine's dosdevices directory and configure IAR to use the FET Debugger on COM1: for the magic to happen.

It's nice to have a choice.

How did you get to activate your copy of IAR? I'm trying to activate the 4KB license on wine-based IAR installation but always get this error:

Failed to request licenses
Could not get the right locking code

No available machine id for specified lock selector. Status code 0x97.
