FAQ # 1 Unable to flash and I get "Programming FAILED: sending 3020"
99% of time this is connectivity or power issue
Check you are selecting the correct comm port
TX of OSD must connect to RX of programmer
RX of OSD must connect to TX of programmer
Programmer requires all six pins connected
Nothing else must power the OSD when programming. Only the USB programmer
Let me know if it works!
Any luck?
The only things I think could impact this:
1 board is powered up by something else. Or have large capacitors on power line.
2 the DTR pin is not connected end to end.
3 faulty board / programmer. Maybe it is set to 3.3v instead of 5v?
4 the minim does not have standard Arduino 56k bootloader. I only know of one manufacturer who did this and it wasn’t a minim style board.
5 the bootloader is corrupt – but I would expect it not to start up so extremely unlikely.
Great. glad you are up and running!
