@zmetzing do you have any experience with programming AVR chips, and would you be willing to help a guy out? I’ve been trying to help my son build a TinyTesla for a while now, and we just got around to testing the thing, and blew a chip.
I have a replacement chip. I have the source code for the firmware, and I have reflashed the attiny 85, but I can’t seem to get it to work. I’m not sure if I’m just missing something. ANy pointers would be greatly appreciated. Also the original chip was an Attiny 85 10pu, and the new one is Attiny 85 10pu. Not sure if that is enough difference to make it not work. By not work, I mean that when I plug into a usb port it is not recognized.
I am using a tiny avr from Tanner to load the firmware. It seems to go on fine, and verifies. My only concern right now, is if I read the firmware to a file, it seems to be off by comparing to the source, but if I just the dvrdude to verify it, it comes back fine.
I know just enough to be dangerous here.
