I’ve been using Nick Gammon’s “Atmega_Board_Programmer” sketch to program my chips with proper bootloaders with great success for a long time. I recently got a few new 1284P’s and the signature is different from my old ones so the programmer will not recognize them.
Here’s what I get upon connecting to the serial monitor.
Attempting to enter ICSP programming mode ... Entered programming mode OK. Signature = 0x1E 0x97 0x06 Unrecogized signature.
The old signature was :
0x1E 0x97 0x0[b]5[/b] Only being different in this one value. I figured this may be a change from the manufacturer on newer models? Either way, I want to let Nick know, and ask how I can add this signature into the recognized signatures.
