have you rebuilt MSP430mspgcc.dll/so and HIL.dll/so too?
Yes.
After looking at the various JTAG lines with a scope I noticed that the RESET
line (which is also SBWTDIO) wasn't be pulled to ground when running
msp430-jtag. The supervisor chip I am using has a push-pull output
rather than an open-drain. I added a 10K
series resistor and the RESET line now looks correct.
After looking at the connections on the PCB I reflowed the pins on the 2012.
The chip programmed twice but fails to program the majority of the
time. Tomorrow I am going to build another board (or replace the
2012).
Can the parallel port programmer be used in spy-bi-wire mode to download elf
files?
I wanted to try communicating with the board using spy-bi-wire so I downloaded
the gdbproxy and lib files from sourceforge and I get the following
errors (with or without --spy-bi-wire option) ---
debug: MSP430_Initialize()
debug: MSP430_Configure()

Thanks for your help.
