I used the IAR/Kickstart for a couple of MSP430 projects and found it
to be a very good toolset/IDE.

Which one? There are several (IAR, Rowley, Keil, gcc).

The TMS470 family doesn't have DSPs, so even if a DSP BIOS exists it
isn't likely to do you much good.

IAR EWARM in particular is well supported by TI, much more so than the
others I have tried. IAR offers a KickStart version; it has a 32K code
limitation, but the price is right.

AFAIK Code Composter is the only game in town for processors like the
'2812. The compiler is OK, the debugger is far better than nothing*,
but I've never used a captive IDE that I really liked.
* But then, any debugger is far better than nothing.

At the last MSP430 "event" I went to, the TI FAE openly discouraged
anybody from using CC for the '430. The freebie demo kits they gave
out contained an IAR demo toolchain. I did use CC for a TI DSP once,
and though it basically worked, it wasn't nice.

There's a reason they named it "Code Composter". Too bad they
misspelled the second word.

Welcome to the club :-) (or the jungle?) If you just started with TI,
you should be prepared to face in any field that they are involved
industry-standard things (ARM, Linux, etc.) but done in unique "TI
way". There is a lot of non-sense on many layers, which even TI field
support in many cases fail to explain. But that's the reality, and
their prices are good for most products (nonsense included).

I think that DSP/BIOS for ARM doesn't exist (at least I never heard
about it existing for anything besides C3000/5000/6000 family). TI
likes to focus on its core business and they see development of
toolchains (like DSP C compiler) and OS (DSP/BIOS) as necessary evil.
They introduced ARM-based DSPs for one of the main reasons the sake of
taking advantage of Linux, GCC and other industry-standard tools and
gradually phase out sales and support for own "side" software. However
here the right hand doesn't know what the left hand does: in the mean
time they have to support all the parts and provide interoperation
between them; TI guys that do the work do it in their own way, and now
we have what we have :-(
Just a month or so ago TI and CodeSourcery announced that CS would
port GCC to C6000 to replace TI's toolset. A good beginning but there
are yet "miles to go before" we get it, and if it will not be
abandoned in the middle.
Sorry for long passage just to say at the end that we've got what
we've got. There's a lot of "nonsense" in TI's infrastructure, but as
long as there prices are good it's "take it or leave it" situation. If
you absolutely can't get along with their tools then you may try some
open-source support for their platform (my experience tells that in at
least 95% of cases it will either not work at all or not do what is
written on TI's product box) or switch to another vendor (not easy
because TI's prices are tempting).

If you switch to something different and stick to TMS470 you will lose
TI support.

The one is only reason is that if you later complain to TI or Spectrum
Digital that something doesn't work and tell them you're not using the
"authentic" tools they will tell you "we have no idea what you're
talking about".

It won't work with TI. They are too big to care about any particular
customer lost and they never claim that they do things in any way
"sensible" to third-party judgement. OTOH their prices are usually too
tempting to throw away their offer just because you can't fight stupid
tools.

Ouch. There are a bunch of nice ARM toolsets out there, I see no reason
to be trapped into one that sucks.
Maybe you should start annotating your bills: so many hours problem
solving, so many hours designing, so many hours wrestling with stupid
tools...

Hello All,
I have to use a TMS470 C/C++ compiler (TMS470 == ARM). The toolset
wasn't my choice. The more I use it, the more nonsense I discover and
more doubts I have. Also, in theory there is TI DSP BIOS for ARM, but
zero documentation.
I suspect those tools are kinda unloved by TI, and I am the only one who
had ever tried them, and the earlier I switch to something different,
the better. Is that really so?
