I'll use the ArduinoISP sketch really only for uploading normal sketches. So in the end I'll be using OptiLoader to burn boot loaders. The dude that wrote it knows what he's doing, no doubt.īTW: I ignored pin 9 for power and supplied my own. The OptiLoader sketch worked every single time! Never an issue. Ultimately, I found burning bootloaders with this method unreliable. Use the Burn Boot-loader command in the Tools menu.

Select the Arduino as ISP in the Tools > Programmer menu. It didn't need capacitors or resistors on the Uno's reset pin. Select the item in the Tools > Board menu and be sure to select 'ATmega328 on a breadboard (8MHz internal clock)' when burning the bootloader.
#UPLOAD BOOTLOADER INTO ATMEGA328P CHIP FROM NANO ON ARDUINO 1.8.5 UPDATE#
I will update if I get this going.Įntry later in the day: I got the ArduinoISP sketch, running on a Uno R3, to burn bootloaders onto a slave ATmega328P chip on a breadboard. Anyway, got faked by the upload, still failing at burnBootloader. I can't seem to delete my comment here and re-editing is not working. My configuration is an Arduino Uno rigged to a ATmega328P-PU on a breadboard (with clock, etc.), with the lines/circuit noted in comments near the top of the ArduinoISP sketch (plus the capacitor and resistor).Īrg. For an exceptional site covering stuff like this, check out (this is where I got the capacitor idea). Pin 10 is the slave reset pin used by the menu File → Examples → ArduinoISP sketch. I put a 10 kΩ resistor between Reset and 5 V, AND, I put a 0.1 ♟ capacitor between my Uno's pin-10 and the target chip's Reset pin. The resistor pulled high between Reset and 5 V, nor a 10 ♟ capacitor between Reset and GND worked for me.
