bslsh - MSP430 BSL frontend for Linux/Un*x

bslsh is a program to upload code and to inspect the system of MSP430 devices through the BSL interface. You can think of it as a primitive system monitor. bslsh currently features:

• code/data upload/flashing
• disassembly of memory contents
• poke/peek of memory
• execute code
• dump memory
• fill memory
• erase memory/flash

Hardware

To interface the MSP430 hardware you need to build a simple interface for rs232 to 3.3V voltage conversion. This is a slightly modified version of the official BSL interface from TI, specially designed for our bslsh program. We have removed the power supply via PC-RS232 and added a power supply through the BSL connector. Further we have modified the reset logic, so the MSP430 doesn't get the reset signal if the interface is deconnected from the RS232 port.
