Ok, so I am trying to upload the hex file provided by Parasit for his Bitbreaker deluxe and I am at my wits end. I am using a USBtiny programming stick (that was kindly sent to me by none other than @fig) and after a couple of days have gotten the right downloads and setup for AVRdude to talk to the programmer, but the vital part missing is it can’t find the hex file to upload. I have tried saving the file directly on the C drive, on the desktop, in the Arduino ide temp folder, documents, downloads, everywhere I can think of, but avrdude still returns a “can’t find the file”. What am I missing!? Also, if I have copied the bootloader to the attiny85 via IDE and then run the avrdude, does that erase the bootloader? Any help appreciated (@damianvila i’m sort of looking at you, but I know you are running Mac and I’m on Windows so it will no doubt be different).
