program avr128da28 chip using arduino uno as a programmer

[hoka83]

hello does jtag2updi support avr128da28 to be programmed by arduino uno? , i want to program avr128da28 chip using arduino uno as a programmer, can anyone provide me steps to do that

Hi! Spence doesn't support jtag2updi any more. You can try to use avrdude directly. There should be support for the avr12da28 since version 7.2.
You should give SerialUPDI a try: https://github.com/SpenceKonde/DxCore/blob/master/README.md#updi-programming-hardware

i watched this video on youtube which Program an AVR DA MCU Using an Arduino Nano but in my case i have AVR128DA28 chip and arduino uno , i connected the pins as the same he did and it gave me error while burning the boatloader

i am just connecting arduino uno as a programmer for AVR128DA chip using updi and it gives me this error:

avrdude: jtagmkII_initialize(): Cannot locate "flash" and "boot" memories in description

this method worked fine in the video just i watched on youtube and i did the same thing and connections but just with arduino uno and avr128DA28 chip

Looks like you have voltage connected to 3.3V instead of 5V even though the logic level outputs on your Uno are 5V? Any particular reason you did that?

We also can't diagnose any potential connection issues to your AVR128DB28 because your photo does not show us that chip, there are no labels on where the wires are going into the green PCB, and you have not provided a schematic of that board.
