Starting with ARM

[charnyutk]

ARM software like rasonance IAR KEIL are the choice for you to develop.
many ARM cpu have difference its' peripheral. you can select it by yourself.

Hallo, I will start with ARM7 in a few months. I want use GNU + CrossWorks studio + FTDI based JTAG cable. Does anybody use this combination?

Hi.. I need your help..

I'm a new in ARM processor.

I would like to know about the following item.

1.) What company that ARM IC is popular in this time?
2.) What complier that we need to use?
3.) What is the developing step for develop some project. But I would like to use Linux OS.
4.) I know that this forum is the best of PIC. But ware web site is the best of ARM

Thanks you

, yeah.. i think its enough, to fuel your embedded system programming,

- the toolchain (free) http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/
- www.macraigor.com, ( .. google macgraigor JTAG compatible schematic)

others forum www.mikrocontroller.net, www.mcu123.com (in chiness)

- be "linuxers", with this uclinux.org ->Embedded Linux/Microcontroller Project

But BGA package  , difficult PCB, difficult assembly...

If you want stat with ARM ,ARM Cortex™-M3 is the last architecture for  ARM7TDMI-S ,have high-performance,implements the new Thumb-2 instruction set architecture and have Harvard bus architecture.Now only  STMicroelectronics have STM32 (CORTEX M3) - 32-bit Microcontrollers and Luminary Micro make Stellaris® family.For 50$ buy LM3S811 Evaluation Kits,the kit features JTAG wich work with  Keil™ RealView.

Hellol, soter  You have JTAG Debugger for ARM Microcontrollers SCH and What is Program to run with the Jtag Debugger. Thank you!!! 

[digitalmg]

http://www.hjtag.com/download.html  soft and WIGGLER Schematic,supports SDT2.51, ADS1.2, REALVIEW and IAR.
but the speed for debug with wiggler is very slow.

I know this post is very old, but I thought this info could still be usefull to someone else
ST have cheap 32Bit ARM CORTEX-M3 processors ($1-$3)
and the best IDE + compiler + debugger is
http://www.atollic.com/
it has free edition with little limitations
http://www.atollic.com/download/Atollic_TrueSTUDIO_Feature_comparison.pdf
and then you use the ST-Link Jtag (low cost) to debug and program
The IDE is eclipse, you can then look as FreeRTOS (Free real Time Operating System)
http://www.freertos.org/
and lwip (light weight IP stack also free)
http://savannah.nongnu.org/projects/lwip/
So you only pay for JTAG and the processors (the way I like it ;P )

[Added:2011/02/04]
I have to take my words back
the atollic is not the best compiler, the limitations is to great once you try to use the lite version for a full development
Sorry for providing wrong info.
I am now testing hte IAR compiler with eclipse plugin

FTDI - based JTAG used it with openocd + EWARM (GDB server)
http://www.joernonline.de/contrexx2/cms/index.php?page=127
usefull docs:
-EWARM_UserGuide.ENU.pdf
-Hitex lpc-arm-book_rev10.pdf

Good start point is open environment supporting with brand company.
