I've been trying to get Mighty1284P to work for over 3 days, and i can't get it to upload sketch using serial! Here's what I did:
- Downloaded the new https://github.com/JChristensen/mighty-1284p core, and burned the Mighty 1284 16MHz using Optiboot bootloader to my ATMEGA1284P using Arduino as ISP
- I connected the Arduino's reset to ground
- Loaded the blink sketch
- Connected arduino's Rx to Mega's Tx and Vice versa
- Clicked upload, reseted Mega, and it says that programmer is not responding.
Please help me.. Thank you.
