MSP430 Programming problem using MSPGCC win32 pkg - help!

[Rob]

Hi guys - we are using the Win32 MSPGCC package from sourceforge and are
having a little trouble programing the microcontroller (MSP430F149).

Via our JTAG programmer board we can connect to the micro, read the device
identity, Vcc voltage and dump the register values etc ok. However when we
try to download the binary program file we have problems.

The messages we receive are:

Debug window - "memory access error when loading section.txt".
GDB Proxy Window - "Could not write to device memory"


If we try to erase the device using - "monitor erase all", we get a message
back stating "received command erase, could not preserve/restore device
memory (12)"

From the above it seems our JTAG programmer and the test board/connections
are all working ok. The PC is running Win XP if this is of any relevance.Has
any one any advice as to what our problem is?

TIA

regards
rob

With the external power disconnected, and the JTAG connected I use the
command:

"msp430-jtag -ep a.out"

to both erase then program the flash. Typing the command causes the board
to power up through the jtag connector.

Don't know if this is relevant to your problem but maybe?

Hi Richard - thanks for the feedback, it could be the problem. I'll check it
out during the week.

I had all sorts of similar problems when I started using a setup like
yours - MSP430F449, parallel port JTAG, mspgcc. My target hardware was
powered by an external DC supply. When using the JTAG however the board was
also getting power through the JTAG connector. I found that if I unplugged
the external supply whenever I was using the JTAG then all the problems went
away.

With the external power disconnected, and the JTAG connected I use the
command:

"msp430-jtag -ep a.out"

to both erase then program the flash. Typing the command causes the board
to power up through the jtag connector.
