I am just about to start working with a couple of ATMega128RFA eval boards and I think I need a JTAG programmer.  I've been doing some research, and it seems that there are a couple of revisions of the JTAG standard (mkII and mkIII?).  The documentation says that I need a Atmel AVR JTAGICE mkII or Atmel JTAGICE 3.

 

Will something like this do the job?  https://www.olimex.c...ers/AVR-ISP500/

 

Or am I better off just buying the "real" thing from Atmel?

 

In case dev. software matters:  I will probably be starting off using IAR Embedded Workbench 6.1 (because I already have it from mucking around with the STM8s).

Hi

 

I think what you linked to is an in circuit programmer != JTAG

Try this for JTAG https://www.olimex.c...ers/AVR-JTAG-L/

 

 

That said an AVR ICSP is also be very useful for flashing, but JTAG lets you debug as well. (Well thats my understanding of it anyways might well be wrong )
