inexpensive way to get into ARM? |
|
|
Hi - do to the recent reccomendations from a number of people here - I
think I should get familiar with ARMs. Is there an inexpensive way to get
into them? I mean for example, when I started programming AVRs, I bought a
couple AT90S8515 chips and an AVRICE, probabaly $45 total - and I was set.
So are there any fairly inexpensive programmers for ARMs? And do most
people code for them in assembler, or C, or something else? (I've only
programmed in assembler, though I do plan on learning C in the near
future). So what software would I need? I'm hoping not to spend an arm and
a leg on all of this, being that I'm just another broke college student.
Also - does anybody have any suggestions for a good chip to begin with?
Thanks so much!

Hi,
For hardware see: http://www.olimex.com/dev/lpc-p1.html with an olimex JTAG
wiggle. Very low cost.
For compiler see: http://www.gnuarm.org (free), or http://www.keil.com
(eval version is not time limited)
Regards,
Richard.

The Philips LC210x is the easiest ARM chip to use, see my web page:

Oops - just wanted to clarify that I meant AVRISP, not AVRICE.

Is this what you mean by the JTAG wiggle? http://www.olimex.com/dev/arm-
jtag.html. The price is right - but it seems that they're syaing that it
has a limitation with programming Philips LPC21xx chips that only the
Rowley compiler can overcome, and at $200/license for the educational
version of that, I don't see that as a feasible option. Will that
limitation be a serious problem if I use other compilers? Or do all
reasonably (a relative term I know, but understand that I'm a broke
college student) affordable programmers suffer from this problem?
Now from what I can tell, gnuarm is a C/C++ compiler for ARM chips. So
should I take it that it is standard to write code for them in C/C++,
and not assembler? I must admit that my experience with C is very
limited, though I do plan on trying to become more familiar with it in
the next couple of months, while I am alot more familiar with assembler.
Thanks for your help,

Am I right in thinking that the ARM JTAG programmer here:
http://www.olimex.com/dev/arm-jtag.html would not be able to program
that chip? On your web site you mention that it's possible to add a JTAG
connector, but according to the Olimex website it cannot program such a
chip. What am I missing? Thanks,

Currently there is no low cost flash downloader for the Philips. We will |
be offering one for around $175-$200 in Jan 2005. Our compiler will also
be available then, for $199.

Of course the Olimex JTAG can program the LPC2000 devices, as well as other
ARM chips like those from Atmel! Mine does as well. The Olimex boards come
with a JTAG connector. I left it off my board because the chip may also be
programmed via an RS-232 port and I wanted to keep it as simple as possible.
JTAG also allows debugging, which is very useful.

It is actually compatible with the Macraigor 'Wiggler':
http://www.macraigor.com/
A genuine Wiggler is quite expensive, but it's quite easy to design
something that does the same job, like my JTAG interface.
The Wiggler type of interface works with most of the development software
that is available, including Rowley's, and gcc which is free (gnuarm). Join
the LPC2000 Yahoo group for more info:

Most people use C with ARM chips, because the compilers are very efficient,
but they are quite easy to program in assembler.

Not entirely true Richard. It is quite possible to program them over the |

Of course it's not JTAG but the connector is a little smaller.

I am sorry. I may be giving the wrong impressions. Let me rewrite that. |
Most ARM flash MCUs have a bootloader builtin, so the eaiest way to get
start is to use that and the cost is usually free. It uses a serial port
and may not have fancy stuff, but it does work.
As a tool vendor, my goal is a bit different: I want to support a single
interface if possible, , plus I want the same interface to support
debugging, so that leaves the JTAG dongle. Currently, I am not aware of
any low cost JTAG HW/SW combo that supports the LPC2K series and we will
be filling the gap.

Hi Michael.
I have used the Wiggler from a Win32 host with the FREE OCDLibRemote tool as
an interface and the FREE GNUARM compiler using the FREE programmer from
Philips along with the FREE Insight graphical debugger... The Wiggler can
be used to program the flash also but takes longer.
These software tools are all free but you have to invest some time in
setting them up. I have only done it from a Win32 host but have found all
the tools prebuilt and working well. The debugger has some quirks. If you
want a flash interface and all the setup done for you then I suggest Rowley,
but it is not necessary.
This page has links to all the tools and a description of how to set them up
and use them:
http://www.freertos.org/portlpc2106.html
See the
"Building and executing the demo application - Debug via JTAG"
"Building and executing the demo application - Standalone from flash "
sections. These pages talk about using an RTOS, which I don't suggest for
yourself if you are new to C, but the setup procedures are not are the same
with or without the RTOS.
Regards. |

You can reflash the Philips LPC2xxx ARMs over a serial line using
the free tools from the Philips site
semiconductors.philips.com
There is a variety of free, low cost and commercial ARM compilers
for a number of languages. For low cost hardware/software, see
