Burn Arduino bootloader into AVR-CAN

[riodda]

i've purchased an AVR-CAN do develop my can project, for that i am more confortable with arduino to program and my intention is to burn the arduino bootloader in the AVR-CAN.
i've seen that should be possible to do it, what i whant to know is if i can burn the arduino bootloader trought the serial interface or if i have to burn it trought the Jtag interface.
The second question is about the arduino can libraries that will support the AVR-CAN.
Thanks.

Helo Riodda,

There is a built-in bootloader in the AT90CAN128 chip but we have never used (so there is a good chance that it will not do the job). What I can give you as a pointer is to check page 321 of the user's manual of the AT90CAN128 (here http://www.atmel.com/Images/doc7679.pdf) - maybe some of the instructions on how to connect to the bootloader via the RS232 or the CAN, would provide useful.

Also there is no ICSP interface out-of-the-box - so ISP programmers will not do the job (unless you know how to access the ICSP). Only JTAG interface is available for programming and debugging. If you are purchasing a tool make sure it has JTAG interface!

If you haven't stumbled upon these please check it:

Thanks i will give it a try.
I will love if you will produce an arduino compatible version out of the box !
Thanks.

I'm going to try to program the AVR90CAN, but i would like to know if i'm doing something right doing the following:

I connect from my USBtinyISP MOSI to EXT1-5 RESET to EXT1-7 SCK to EXT2-33 MISO EXT1-14 then i sould put a common ground between the USBtiny and the AVR but then i'm puzzled about the power do i need to power the AVR from the ICSP connecting the +5V to EXT2-6 or i can power the AVR from an external source using the EXT1-1 ?

Thanks.

This adapter will work ?
Sorry if is wrong but is my first eagle file, JP1 will connect to EXT1 and JP2 to EXT2 and then ICSP will go in JP3.

I've built an adapter with the above schematics but i have no connection with the USBTiny, what i did wrong ?
Some help will be apreciated.
