My current situation -
Custom PCB designed by me. Using an ATMEGA 2560 without bootloader. 16MHz and two 22pF caps. 10k pullup on Reset. 100nF cap on DTR line.
Trying to use the UNO as the ISP using the code in the example. I put a 10uF cap from GND to reset and tried to bootload the thing.
I get this error when not pressing the reset button before bootloading -
avrdude: stk500_getsync(): not in sync: resp=0x15
I get this error when pressing the reset button before bootloading -
avrdude: stk500_getsync(): not in sync: resp=0x00
Any ideas? I really need to get this thing working sooner rather than later. If anyone has already got their MEGA2560 working let me know!
