Producing TI text files

Hello all,

I need to produce a Ti .txt file to use with Ti USB BSL utility.

Caveat - I already have ihex2titext.exe which came with some ancient
version of MSPGCC. The exe file is dated November 2006. The problem with
this version is that it generates one contiguous listing for main code
memory, eg:

This seems to crash the Ti USB BSL utility (or crash the on chip code which
then causes the utility to crash). When I use a program like Elprotronic to
program this file and then read it back off the chip I get a file which
looks like the following:

Data blocks continue in groups of 256 bytes per block.

I've checked and it is definitely not the uppercase/lowercase difference
between the two .txt files.
I've also checked and it isn't the last block length/padding (all blocks in
the elprotronic file are 256 bytes long and start on a 256 byte boundary).
I believe it is most likely a bug in Ti's USB BSL utility or in the USB BSL
code on chip which is avoided by breaking the data into 256 byte blocks.

My question: Does there exist a more modern tool for creating Ti text which
might break up the blocks in this manner? My long-term fallback position is
to get the python code from CVS, rework and rebuild it. I'd rather not
since I've never worked with python and don't have a lot of time for this
side project.

Thanks for your advice
