I'm working on a tool to read and write from the BDM path (BKGD) and I found Podex's project https://github.com/george-hopkins/podex the project he made is very simple and easy for me to understand
but the problem is that it uses AT90S and this microchip is old and hard to get in my country.
I want to change it to ATmega to make it more affordable and available, but I am not very familiar with Assembly. is there someone who can model what needs to be changed.
And I'm waiting for the PCB order for ATmega to arrive.
Thank you
