This is an mspdebug wrapper for use in scripts.

Use this wrapper to run a program on an MSP430 attached to your PC (via a hardware debugger such as the [MSP-FET430UIF][fet]) and gather its results. Given an executable, the wrapper invokes mspdebug, sets a breakpoint at a location of your choosing, runs the program, and dumps the register values to a file when that breakpoint is reached.

Usage

Invoke with -h to see options. Most crucial is the -b option that sets the breakpoint. If you have defined a function stop_here(), for example, that will be called when the program is done, you can run

$ python mspdebug-wrapper.py -b stop_here -o regs.txt myfile.elf

Collect the register values from regs.txt after the program runs.

Or you can use the MSP430 version of binutils (see "Dependencies" below) to hunt for a specific instruction that is called after the program completes. This instruction will vary from program to program. Just one example:

$ msp430-objdump myfile.elf
...
    446c:       81 4f 02 00     mov     r15,    2(r1)   ;0x0002(r1)

$ python mspdebug_wrapper.py -b 0x446c -o regs.txt myfile.elf

Dependencies

  • mspdebug
  • msp430-binutils or binutils-msp430 from your system's package manager to inspect executables as above
