Good Morning, I fabricated an Arduino Uno clone with an ATMega328P-PU chip.
Once done, i tried to burn the bootloader with an Arduino Mega. I had a lot of problems but I think that finally the bootloader was uploaded correctly. I did that as the following instructions:
1.Examples->ArduinoISP. 2.Board=Arduino Mega, Programmer=Arduino as ISP, Port(COM)=OK. 3.Upload the ArduinoISP inside Arduino Mega. 4.Make the following conections (Mega-UNO): 50-D12, 51-D11, 52-D13, 10-Pin 1 of the ATMega328P-PU, Vcc-Vcc, Gnd-Gnd. 5.Board=Arduino Uno. 6.Burn the Bootloader.
*Some tutorials said that I should conect Pin 53 with Pin 1 of the ATMega328P-PU but I tried it and it didn't worked.
After that I tried to upload the Blink program. I was exited so I forgot to change the conections but the blink uploaded and worked. I could change the frequency few times but after that I've could never change the program (it is blinking wiyh a 1000ms delay).
Is the bootloader installed? (I think it is, because it is blinking). How can I upload a new program? (I tested different conections and never works).
Thank you very much.
