I don't want to sound demanding, but has no one tried Olimex's USB debugger
with the python tools? What is really frustrating is that gdbproxy appears
to work fine with the same hardware, but I can't see how it accesses
memory - as far as I can see, the relevant parts of the gdbproxy code are in
the secret NDA code.
I've made a couple of minor changes to msp430-downloader.py, which I think
could be worth putting in the official version. They are so small that it
is probably as easy for a maintainer to cut-and-paste rather than using
patch:
In the list of file types (line 26), the box is a little more user-friendly
if we use:
typeList=[('Binaries (*.hex, *.elf, *.a43)', '*.hex;*.elf;*.a43'),
'hex', 'elf', 'a43', '*']
I also replaced the confirmation box with a choice of interface, supporting
USB on windows:
answer = EasyDialogs.AskYesNoCancel("Use Parallel port JTAG or USB JTAG?",
default=1, yes="Parallel port", no="USB")
if answer == 0: #NO -> USB
lpt = 'TIUSB'
elif answer == 1: #YES -> Parallel port
lpt = '1'
else: #CANCEL
sys.exit(1)
This might need to be optional when running on Linux (until there is support
for the USB tools on Linux). Of course, I couldn't test that programming
works here - but erasing is working fine...
mvh.,
