Ethernut JTAG
JTAG Connector
This has been tested with Nut/OS Version 2.4.2, AVR-GCC 3.2 or ICCAVR 6.25
and
AVR Studio 4.04.
Works with AVR-GCC object files only, not with elf files or coff files
created by elf2coff.
No variable watch with GCC, only ICCAVR offers this feature.
Press cancel when AVR Studio requests GCC's gcrt1. Don't forget to modify the Makefile when using GCC. Uncomment line with
compiler
option -g and -O0. AVR Studio may crash while debugging Nut/OS. However, debugging your
application is
typically no problem.
ICCAVR users may check the beginner's tutorial about
Using ImageCraft C .
It demonstrates how to build and debug a webserver application with a JTAG
debugger.
