А с какъв JTAG го караш Kiel-a?

How to work with IAR, KEIL, GH, ARM compilers and ARM-JTAG?

Hi,

yes, now this is possible as a guy from China named TwentyOne made H-JTAG RDI support for Wiggler compatible, thus made possible ARM-JTAG to work flawless with any commercial debugger which suports RDI: this means EW-ARM, uVision, ADS, STD, RealView, GreenHils etc.etc.

For these of you who are not fans of the command line interface and GCC, here is what you have to do:

1. install your favourite IDE from above (almost all of them give free trials or limited versions), for instance the 32KB limited free kickstart version of EW-ARM from IAR Systems

2. install H-JTAG package from the link of our ARM-JTAG page, use the version from our web as our ARM-JTAG have some additional signals than the Wiggler clone schematics which circulate on the internet. TwentyOne was kind enough to adjust his code to support our ARM-JTAG and the code on our web is made specially for ARM-JTAG.

3. setup H-JTAG with JTAG settings: Wiggler nTRST = D0, nSRST = D4, check nTRST output inverted checkbox

4. In EW-ARM make new project with options as Debugger: RDI support and in RDI browse to H-JTAG.dll

that's all folks, now you can compile, flash load, debug your application without the annoying speed setups and so on as with OCDeamon.

And *VERY* interesting fact: although Segger claim that their J-LINK program with 120-250KB/sec we can't see this happend on LPC microcontrollers and boards we have! The flash load/programming speed with ARM-JTAG ($20) device is about 30% slower than the J-LINK ($250) USB debugger when you load your code in LPC flash.

We don't have any other commercial debugger to make comparison to.

Have fun!
