Hello.
Recently I bought board AVR-CAN, which is equipted with AT90CAN128.

I have programmer USBAsp, when I tried to program it , my computer disconnected the programmer with error "Overcurrent on USB port..". This happens also with connected of external source to the PCB.
I tried it also with STK500v2, but the same result.

The both programmers are working (tested on another PCB).

I wanted to know if you can suggest some way how to make it, or what type of programmer would do the work?

Thank you

Hey Metodej,

Did you notice the connector in AVR-CAN is named JTAG (not ICSP/ISP)?

You have to use AVR debugger. The board was designed this way for easier debugging.

Now to tell you honestly there is a way to implement ICSP interface but that would require cutting an element from the board (which would void your warranty) and using 10 jumper wires. If you wish I can give you more details.

Ah, sorry, I missed that information (no ISP programming).

I saw the post here on forum about how to make the ICSP work, but I rather prefer to keep the warranty (at least for first tests).

Thank you very much for help ;)
