MSP430 LLDB Debugger

This is an LLDB-based MSP430 debugger which has been developed to work with the mspdebug gdb-server (note that mspdebug can be used as a standalone debugger).

Check out the slides from the tutorial given at Euro LLVM Developers' Conference 2016, Barcelona: ... (to follow after the conference)

In Codeplay/examples, you will find source code for the examples that we use in our presentation. Use them at your own risk.

Getting Started

The MSP430-LLDB repository is based on LLDB release 3.8. Note that LLVM 3.8 is also required. It can be obtained from here: https://github.com/llvm-mirror

Tried & tested build systems:

• CMake Tried & tested compilers:
• gcc 4.8.5
• clang 3.8 Tried & tested platforms:
• Linux Tried & tested hardware:
• mspdebug simulator
• MSP-EXP430G2 LaunchPad development tool

Building with make

mkdir build && cd build
cmake -G "Unix Makefiles" -DLLVM_TARGETS_TO_BUILD=MSP430 <llvm_root_directory>
make lldb

Compiling MSP430 examples

Step 1: Obtain the cross-compiler and binutils. 

On Debian-based Linux distributions:
> sudo apt-get install binutils-msp430 gcc-msp430 msp430-libc mspdebug

Downloading from the vendor:
> http://www.ti.com/tool/msp430-gcc-opensource
> http://dlbeer.co.nz/mspdebug/

Step 2: Compilation
> cd lldb-msp430/Codeplay/examples
> msp430-gcc -mmcu=msp430g2553 -O0 -g led.c

Debugging with MSP430-LLDB

Step 1: Start mspdebug in gdb-server mode
> mspdebug sim
(mspdebug) prog led.elf
(mspdebug) gdb

Step 2: Start lldb and connect to mspdebug (by default uses port 2000)
> lldb
(lldb) file led.elf
(lldb) settings set plugin.process.gdb-remote.target-definition-file <lldb_root>/examples/msp430_target_definition.py
(lldb) gdb-remote 2000
(lldb) b main
(lldb) continue
