I'm just going to start by saying, i'm a complete beginner at all of this and am mostly just trying to help my father upgrade his computer to make it easier for him to work with. I really appreciate any help y'all can give me!
So far i have followed instructions on flashing a bootloader onto my ender 3 board using an Arduino Uno R3, but after that I was still unable to connect to the board directly from my computer via usb, No COM would show when I was wired. I am now just trying to flash the firmware onto the board using the arduino as isp but i'm getting an error after the sketch has compiled. Here is the Error i am receiving
Again thanks for any help!
