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.
