The only way to fetch the source for this tool is to install a binary blob for AMD64.

wget "https://dr-download.ti.com/software-development/software-programming-tool/MD-szn5bCveqt/1.03.20.00/MSPFlasher-1_03_20_00-linux-x64-installer.zip"
unzip MSPFlasher-1_03_20_00-linux-x64-installer.zip
chmod +x ./MSPFlasher-1.3.20-linux-x64-installer.run
./MSPFlasher-1.3.20-linux-x64-installer.run
cd "$HOME/ti/MSPFlasher_1.3.20/"
tar -zcvf mspflasher.tgz Source/

First install libmsp430.so.

Extract files and apply makefile fix.

sudo -s
mkdir -p /opt/src/MSPFlasher
cd /opt/src/MSPFlasher
tar zxvf ~/mspflasher.tgz
cd Source

sed -i 's/char  cOpt;/int cOpt;/' Support.cpp
sed -i 's/-lmsp430/-lmsp430 -lpthread/' Makefile

This patch is required to stop the app entering an infinite loop.

Make the binary and install it.

make
cp ../MSP430Flasher /usr/local/bin/

When you run this app unpatched with args it will enter an infinite loop, hence it's useless without the fixes found on the TI forum.

Whether the target works or not in Linux is also dependant upon the firmware version in the target which can be upgraded via libmsp430.so using mspdebug.
