Beginning Microcontrollers with the MSP430

i have got 3 months for my project starting from this may . i m afraid
i wont be able to complete my project in 30 days. yes ,IAR evaluation
version may be helpful in the last moment. for now i think i have to
use gcc only..: )

Hi,

Or you can use vmware server and some email addresses to reinstall the tools
if you cant get your code finished by 30 days.

Objet : [msp430] Re: MSPGCC to compile and IAR to link and other stuff

Thank you, you are right! i have to do some thing like that. i am also
trying to contact some ppl who have used the mspgcc , so that i can
get a taste of it before i start with it. i have only 1 month time to
decide upon these...: 0

What is the time schedule for your master project?

There is an evaluation version of the IAR IDE besides the kickstart
version. The eval version is fully functional for 30 days after
installation. If you do no commercial product development, there
should be no problems with Anders ;-)

Of course this is not an ideal solution, but maybe it can help you if
other attempts fail (mspgcc...)

Perhaps you could ask the IAR folks to give you a license for your
project, maybe one that expired in a year or something. It would be a
shame to spend all of your time wasted on things like getting your
toolchain straight, rather than working on the "meat" of your thesis
project.

Travis already described the 4KB limit of KickStart (And he is correct.)

But yes, in a sense, "things" can exceed 4KB. I am very interested in
your evaluation kit idea. If it is going to be in public domain, I
will be very happy to help you.

What sort of pre-built object files and constants do you have in mind?
What size? And which MSP430 or MSP430X (capital X)?

Howdy Anders and gckir,

The linker enforces the limit, so you'll need the GCC--not the
IAR--linker. Although it's possible, you'll never be able to do it for
less than the cost of an IAR license.

GCC uses ELF. IAR uses UBROF. A UBROF dumper is included with NoICE,
but it doesn't work with either the latest UBROF or the 4kb versions of
IAR. (I doubt the dumper works for un-linked objects, but you could
compile the IAR image and relink with some perl scripts.)

Once linked, msp430-objdump can convert the firmware ihex, which can be
uploaded with IAR's tools.

GCC's calling convention--for 16-bit integer parameters--is to use r15,
r14, r13, r12 in that order, and to pass all subsequent parameters on
the stack. A return value is placed in r15.

IAR's convention in version 3 (of the compiler) was to use r12, r14 in
that order, and to pass all subsequent parameters on the stack.
IAR version 4 uses r12,r13,r14,r15 in that order, and passes all
subsequent parameters on the stack.
Both versions of IAR place return values in r12.

What _exactly_ are the limitations of KickStart ? I've heard that
things can exceed 4K, under some circumstances.

I'm interested because I'd like to make an eval kit
for something that users could use with KickStart. This
would include pre-built object files (some of which
contain large-ish data arrays) will these count against
the 4K limit, or only the code, not the data, something
more complex ?

Even if you won the uphill battle Anders described, you still cannot
link more than 4KB of code. The Linker in KickStart has a 4KB limit.
