Hi all,
I've been having a very big problem since 2 days. I got a brand new Atmega328P U-TH IC and made a custom board around it. Due to covid lockdown I am not able to purchase any programmers like USBasp, so I decided to use my Arduino UNO as ISP programmer. However, When I tried to burn the bootloader using Arduino IDE I am having the error " Yikes! Invalid Device signature" I then tried to lot of time hustling over this issue and was able to figure that there's something wrong with my fuse and lock bits.
So I tried to write the fuse bits using sinaprog tool and also with avrdude command line however I was unsuccessful in all the attempts. I would like to ask for help on how to resolve this issue. Please ask me for more information if I haven't provided in this message.
Thanks
