I'll be releasing msp430static, my Perl tool for reverse engineering of MSP430 firmware, on SourceForge after my session at the Texas Instruments Developer's Conference in Dallas. The session is in the Manchester Room at two o'clock on Wednesday afternoon. My talk primarily concerns the injection of machine code into MSP430-based wireless sensor nodes, but I'll be doing a short demonstration of the tool following my talk for those that are interested.
UPDATE: The code has been posted at SourceForge. See msp430static.sourceforge.net.
