What is the Atmel AVR JTAG implementation ? If you are looking for a JTAG, XMEGA PDI or ATtiny TPI production programming solution, please check out the Equinox ISPnano range of programmers.Ĭan the JTAG Interface be used for programming purposes ? The 'XMEGA PDI Interface' is now supported allowing Atmel XMEGA AVR devices to be debugged via a 2-wire PDI port. The AVR® JTAGICE mkII also supports the 'debugWIRE Interface' which is popular for debugging ATmega and ATtiny low pin count devices. This firmware is then executed on the actual target AVR device using special on-chip debug hardware. The debugger works by downloading the 'firmware' to be tested into the real target device on the target application board. The debugger supports up to 4 hardware breakpoints where 2 can be used in data memory, and an unlimited number of software breakpoints. When reaching a breakpoint 'AVR Studio' automatically reads out the contents of all memory locations, periperal functions like timers and USARTs and the state of the I/O ports. Using the powerful 'AVR Studio 4' software which is bundled with the JTAGICE mkII Debugger, it is possible to single step, run to breakpoint or run until a certain data address is read or written. The AVR® JTAGICE mkII from Atmel is a powerful development tool for On-chip Debugging (OCD) of all Atmel AVR 8-bit RISC MCUs and AVR32 32-bit DSP/MCUs with IEEE 1149.1 compliant JTAG interface.
