AVR Jtag ICE enables AVR based ICs to be debugged using hardware breakpoints. The JTAG interface is a 4-wire Test Access Port (TAP) controller that is compliant with the IEEE 1149.1 standard. The IEEE standard was developed to enable a standard way to efficiently test circuit board connectivity (Boundary Scan). Atmel AVR devices have extended…
The purpose of this tutorial is to enable the AVR toolchain based debugging using AVaRICE + AVR-GDB combination in newer debian based versions. The avarice version 2.13+svn which is installed using the apt repository seems to broke the debugging. So we would be using 2.12 version of Avarice for continuing the JTAG debugging in newer…
The method is tested in Ubuntu 14.04 and LinuxMint 17 with Eclipse Indigo version. Test debugging in terminal by typing the following commands sudo avarice –erase –program –file LED.elf –jtag /dev/ttyUSB0 :4242 Above command will start the GDB Server on Port 4242. User need to change the filename(LED.elf) to match their binary, and may need…
ATmega16 & ATmega32, having Advanced Virtual RISC Architecture are microcontrollers having breadboard friendly 40 pin DIP package.This post is intended to help beginners program ATmega16/32 IC’s using USBASP. The USBASP is a serial programmer having Serial Peripheral Interface for programming . The programmer consists of 10 pin standard serial connector for connecting to the…
