H-JTAG update

2006-01-03 by tsvetanusunov

Happy New Year to all LPC2000 members :)

During the Holidays one of our engineers tried H-JTAG and there is 
progress!

Our tests show that H-JTAG connects just great to IAR EW-ARM (the only 
RDI support IDE we have at the moment) and works without any problem 
with our ARM-JTAG if you set in JTAG Settings nSRST = D4 (by the way 
while you step your debugger the H-JTAG icon cool change it's color in 
the taskbar).

The bad news is that it doesn't work with any LPC microcontroller!

From all ARM7 boards we have it works only with SAM7 and ADuC7xxx, but 
can't detect LPC2xxx, TMS470, OKI and STR7xx - there is definitely room 
for improvement from He21 :)

Unfortunately as some of you figured out I've been misleaded from the 
sources on the 21 web, this project is not open source and we can't 
work on it and to see how to fix the ARM7TDMI-S support.

By the way browsing the web during the Holidays I found yet another 
free Wiggler RDI support DLL at http://www.armjtag.com/english.htm
looks like less sophisticated than H-JTAG and again not open source 
again works with SAM7S core but don't support LPC2xxx

Best regards
