Programming parts in production (IAR trouble)

Started by Dan Miner April 8, 2005
I have (nearly) finished developing the code for our product
using the IAR compiler.  Since I'm the only MSP430 programmer
at our company, I bought the USB dongle with the license so I
can compile from my office, the lab, or home.

Anyway now that the code is done, I am ready to release the 
binary file to production.  The snag is that IAR seems to only
support programming through C-SPY and would require us to buy
another expensive license.  Email to customer support has not 
been helpful.  As I see it, I have a few options:

1) Figure out which file format (coff; elf/dwarf; other) works
correctly with the free downloader from msp-gcc or similar.

2) Port all my code to msp-gcc or other commercial compiler that
is not so brain-dead when it comes to the needs of a production
environment.

3) Re-write enough chunks of my code to assembler so that the 
remaining portion in C can be compiled with the free IAR compiler
and its 4K limit.  (I already know which one Al would choose.  :-)

Can anyone out there help me?  I need to determine which of the
30+ IAR binary formats will work with <which?> download tool.

Choose the TI-txt file format. It works for TI's program BSLDemo and
pyjtag.




It shouldn't be too bad. If you are talking about the final code, IAR must 
support some sort of HEX output, likely in the Intel HEX format. In which 
case, almost anyone's downloading tool should be able to handle that. Our 
compiler comes with a command line tool that a licensed user can
"give" to 
production people to use for this purpose and I am almost certain that most 
other compilers do as well. So you don't have to switch compiler unless you 
want to.

Dan,
	Try the free MSPFET at http://mspfet.hellos.biz/  We use it
regularly for production programming of our MSP430 based VHF transceiver
and aviation intercoms. Works a treat and nothing more than a FET kit
and the hex file is required.

We use www.elprotronic.com USB programmer.  We have 2 of them, very fast, 
takes msp430.txt .s19 and .hex (as can be produced by IAR).  Going to buy 
some for our distributors too.

Doesn't CSPY works without the dongle?

Under the "Project Options", Category: XLINK, an output file and
format can be specified.  Personally, I got as far away from IAR as I
could a few years ago.  MSPGCC is really great for an open source
project, but doesn't produce thee tightest code.  Given the pricing of
the parts, it is easy to justify spending more on another compiler
that will squeeze the code into the next smaller part.  This very
group had a brisk discussion of the merits and drawbacks of each
package.  Check out the archives for some drama and info on the topic.

Thanks to everyone with suggestions and ideas.  The production
guy I need to work with is away on a business trip this week.
When he gets back, I'll try using the mspgcc download tools
with the proper binary generated by IAR.

The TI gang programmer is great for this, it lets everyone else program
parts without interrupting you. All you have to do it load it with the
production image and it can program up to 8 devices at once with no PC
attached.

It also supports blowing the JTAG fuse.

you can use every programmer/FET/BSL Tool ( 
http://www.gessler-electronic.com/msp430/ ,
http://llg.cubic.org/dmx43/bslsh.html )
etc. without a dongle.
I do prefer the free tools msp430-gdbproxy and msp430-gdb + ddd with the parport

FET but there are other free tools.
