I too am getting this problem, but is is definitely not a power issue.
I have been using the pyjtag for months and last week all of a sudden I
get the "Could not erase the Flash" error. I take the board to another
developers IAR system and using the same pod we can load a large chunk
of code. After that the pyjtag loader will work again for one or two
more loads then the error returns.
It seems that once the code size has reached about 28K bytes that the
pyjtag seems to put something in the MSP430 that creates the failure. I
I am at a loss for what the problem is. I am using a MSP430F149 and am
(trying) to load code of about 33kb right now. Development has pretty
much rolled to a stop until I over come this problem or move on to some
other solution.

Hi,
Somthing happened to my MSP430, and now I can only reset the device
and i get errors whenever i try to write or erase flash
Any one know what this mean ? Or experienced this before...?
$ pyjtag -r
MSP430 parallel JTAG programmer Version: 1.3
Use -h for help
Reset device ...
$
Reset is sucessfull, i can talk to it via jtag...
$ pyjtag -e
MSP430 parallel JTAG programmer Version: 1.3
Use -h for help
Mass Erase...
An error occoured:
Could not erase the Flash
$
Similar error occurs when trying to program???
thanks,

programming and erasing the flash uses considerably more cuurent than
just resetting it. it draws upto 5mA. if your circuit does not provide
that, you may only be able to ease/programm small memory ranges or
nothing at all (until the caps are below 2.7V).

Thanks Chris,
I think that was it.... my 9v battery wasn't sourcing enough
power.... I
left my board over night disconected from the battery....and it works
fine
now... It will probably stop working again.... I will replace the
battery.... that explains the errors i was getting when writing/reading
flash.. but not reseting....
thanks,
Abe
