Tools for JTAG programming (AVR)

[hqqh]

Hi,

i want to program an ATmega128 via jtag. i have read that it is possible with avr studio and ice5 (in circuit emulator).
my question: which tools can program the controller with a simple jtag cable (i have a jtag cable from a xilinx development board)? or do i need the ice5 device?
thanks in advance.

greetings,
hqqh

Hi,

i searched in the net and found (**broken link removed**) a tool that is able to program the avr via jtag. it is command line based and consists of 3 executable. at first you have to translate the .hex file into a svf file. after this the svf have to translated into a .jam format and the you can download the file with a tool called jam.
is there no other tool that makes it a little bit easier? or is flash programming via jtag not a common way.

greetings,
hqqh

hqqh,

I don't think you have to convert from svf to jam (stapl). svf is the xilinx jtag programming format while jam (stapl) is the Altera version. I think the jam (stapl) format is also a JEDEC standard?

Check out the xilinx appnote titled "Xilinx In-System Programming Using an Embedded Microcontroller" located at:

If you list all of the app notes:

and then scroll down to app note 58 you can download the svf player binaries for Windows, Solaris, or HP Unix.
