Atmel JTAGICE mkII

Jan 20, 2009 4 Replies

Hi, as a newbie in this area, I am wondering if I should buy the JTAGICE mkII or the AVR RISP mk II.



Is it correct that the JTAGICE mkII can be used for programming *and* debugging all Atmel MCUs, even the AVR32 range?.



And, is it correct that the AVRISP MKII is used *only* for programming, and it is not usable for the AVR32 microcontrollers?.



Assuming the above ideas are correct, it appears to me that the JTAGICE mkII provides more functionality and options.



thanks


Hi,

You're right:

  • JTAGICE mkII can debug/program AVR (8bit)and AVR32
  • AVRISP mkII can only program AVR (8bit)

I have used both JTAGICE mkII and AVRISP on AVR(8bit) MCUs. However, I haven't used JTAGICE mkII on AVR32, so I can't comment on how good or extensive the debug support is for AVR32...

Hope this helps.

mkII

Not all Atmel MCUs, only all AVRs (AFAIK it will not work with Atmel's ARM parts, for instance, nor the 8051 parts). Do you actually plan to be one of the three people using AVR32?

If you don't need AVR32/DebugWire functionality, I suggest you look at a third-party USB JTAG-ICE clone from Olimex, which is 1/6th the price of the Atmel version and (as far as I've tested) fully compatible - it behaves like a JTAG-ICE mk1 but has an internal USB-serial converter.

Or get the chinese knock off that is an exact duplicate of JTAGICE MKII at half the price.

And, just as a point of interest that somebody may find handy, the inexpensive little AVRISP can, however, program Atmel's AT89S-series of

8051 parts. The sense of reset changes, which one must remember if moving between the two families (not that *I've* ever forgotten, well maybe once ).
