Topic: uploading drivers firmware on ATMega8U2 of Arduino UNO (Read 3473 times) previous topic - next topic

Hi Everyone,

Can I burn the drivers firmware on the ATMega8U2 without using DFU bootloader using external programmer like USBTinyISP?
If Yes, Can anyone let me know the procedure?

Best Regards,
Anil Palaparthi.

Please someone respond to my question.
It's very urgent.

Yes you can!
See http://arduino.cc/en/Hacking/DFUProgramming8U2

I will prepare in a minute a tutorial explaining how to update without soldering.

Thanks Christoph for your reply.
I am looking for a method that updates the firmware on the ATMega8U2 with out the need for DFU bootloader.
But, the procedure in the link http://arduino.cc/en/Hacking/DFUProgramming8U2 needs the DFU bootloader.
and also, the procedure in the above link doesn't use any external programmer like USBTinyISP.
Could you or anyone else please provide me the details on how to upload the firmware on the ATMega8U2 with no DFU bootloader on it using external programmer like USBTinyISP.



I am trying to do the same thing, namely program the Uno's 8U2 using ICSP. I don't have a solution yet, see my other posts:

Please let me know if you receive any further info, and I'll do the same to you.
