Daniel Beer joined us with his open source debugger "MSPDebug" for MSP430 MCUs.
The official MSPDebug-Forum can be viewed at: MSPDebug-Forum
MSPDebug is a free debugger for use with MSP430 MCUs. Right now it supports FET430UIF, eZ430, RF2500 and Olimex MSP-JTAG-TINY programmers.
It can be used as a proxy for gdb or as an independent debugger with support for programming, disassembly and reverse engineering.
