After battling with getting the parallel port FET/jtag interface (on
Linux) to load code reliably for several weeks, I have come accross a
remedy that improves things a lot, for me.
I noticed that the blocksize is restricted to less than 256 bytes
because that is all the RAM available on some 430s. Since I'm using a
msp430149 with 2048 bytes of RAM, it can support a larger block, which
seems to greatly improve chances for success on my particular
workstation. I made the following change to programFlash() in
/jtag/msp430/funclets.c
blocksize = min(count-done, 2048-sizeof(funclet_progFlash));
//TODO: get device memory size
Be carful when rebuilding; the dependencies in the make file are a weak.
I found it necessary to delete
jtag/python/build/lib.linux-i686-2.1/_parjtag.so prior to doing the
make. Otherwise it builds the object but does not re-link _parjtag.so.
