ARM7TDMI -- Jtag debugger...
Posted by Mike V. on April 26th, 2004


I'm interested in purchasing a demo board for an ARM7TDMI-based
microcontroller (a Philips LPC2129 to be exact.) That's fine with me,
it only costs ~$150.

I want be able to debug it with a JTAG debugger, so ~$300 debuggers by
Keil and/or Nohau come to mind.

Salespeople tell me that I can't just stick the Jtag onto the demo
board, but that I would also need to buy their full $2000+ development
suite.

I feel that if I buy the full development suite (especially with my
own money since this isn't for work), i'll have the word "sucker"
printed all over my forehead.

Isn't all I need just the demo board, a limited free compiler (from
where?), a PC, and the JTAG debugger??

Try Chameleon POD from www.Amontec.com .
I am using one for LPC2106 and other ARM boards. This is a very nice
product for debugging !

It works just fine as a Raven via GNU GDB. Amontec adds a -rtck feature,
great thing for ARM -s series like LPC21xx!

The LPC2000 Yahoo group has lots of info on low-cost LPC2000 development:

I've designed a PCB for a very simple DIY JTAG interface that works very
well, if you don't want to buy one.

Hi Ted,

Thanks for the tip to the Amontec site. Looks like a great debugging tool.
Heard of anyone using these for any of the following families:
Toshiba MIPS Tx3927
Motorola: MCF5249, MCF5282... other Coldfires
Motorola: MPC5200, MPC562, other PPC's

Any other 32 bit processors in addition to the great ARM support? How does
this compare to the BDI2000 from Abatron? I've heard rave reviews about
this device... but I believe it costs considerably more.

Regards,

Edwin Bland

Ashling offers a board with on-board USB->JTAG debugger and a
code-size limited version of the debugger for 295USD.

Also they offer versions without CPU and replacements for the normaly
fitter LPC2104.
A free (in terms of not paying money !) compiler is gcc.

? Why spend that much, if funds are constrained - a $10 homebrew
parallel port JTAG wiggler is all you need. The Keil kit (I don't know
about Nohau) is USB-connected and integrated with their proprietary
Windows-only IDE, but to my mind this is a curse, not a blessing.

Salespeople have commissions to earn.

The only way you'd be getting a "limited free compiler" is if you were
eval'ing one of the REALLY expensive toolchains. "The" compiler for
ARM is gcc. *Most* people selling "custom" toolchains are really just
selling custom IDEs wrapped around the GNU toolchain. Some of those
custom IDEs - Keil's, for instance - have limitations. Ignore these
distractions, use the free, unrestricted GNU toolchain natively.

we have a good supplies of JTAG for arm7 board.
