Platform details
| Processor | MSP430F5529 |
| Architecture | MSP430 |
| Instruction sets | MSP430 |
| Memory | 128kB Flash, 8kB RAM |
Hardware modifications
None necessary, attach probes to the 3V3 jumper.
Software setup
udev rules
$ cat /etc/udev/rules.d/62-msp-exp430f5529lp.rules
ATTRS{idVendor}=="2047", ATTRS{idProduct}=="0013", MODE="0666", GROUP="plugdev"
GDB server
To build:
$ git clone git://git.code.sf.net/p/mspdebug/code mspdebug $ cd mspdebug $ make
To run:
$ ./mspdebug ezfet gdb
This starts a gdb server on port 2000, however doesn't seem to allow flashing of the device (although you can debug, and step through programs).
$ wget http://www-s.ti.com/sc/techzip/slac460.zip $ unzip slac460.zip $ cd MSPDebugStack_OS_Package $ wget http://mspdebug.sourceforge.net/misc/slac460f_unix.diff $ patch -p1 <slac460f_unix.diff
$ cd ThirdParty $ chmod +x install_thirdparty.sh $ ./install_thirdparty.sh
$ cd .. $ make $ sudo make install
This creates libmsp430.so, which allows the tilib driver of mspdebug to be used. This seems to be able to successfully flash the board.
$ ./mspdebug tilib gdb
Toolchain
$ apt-get install gcc-msp430 msp430mcu gdb-msp430
The C library can be installed from the package msp430-libc. However this is missing several functions. If trying to run BEEBS on the board then the required version of pow is missing from the library. The following steps patch the library:
$ git clone git://mspgcc.git.sourceforge.net/gitroot/mspgcc/msp430-libc $ cd msp430-libc $ git checkout release/20120224 $ [Put patch file listed below into msp430_libc_patch] $ patch -p1 < msp430_libc_patch $ ./configure $ cd src $ make $ sudo make PREFIX=/usr install
