Bootloader on ATMEGA328P-PU

Using Arduino Microcontrollers
#1

Dear readers,

I'm new in using ATmega microchips as standalone microcontroller. I tried to burn a bootloader on the ATMEGA328P-PU (20MHz) chip, following this topic: https://www.arduino.cc/en/Tutorial/ArduinoToBreadboard and following the instructions without external clock.

However when I try to burn the bootloader I get an error message:

Arduino: 1.6.13 (Windows 10), Board:"ATmega328 on a breadboard (8 MHz internal clock)"

Does someone know what's going wrong? I've tried it with two different new chips.

I'm not at home, so I can't try to replicate, But I can tell you it sounds like what way you are trying to burn the chip. Is it on a homemade breadboard, also what type of connection? Me I do this with success about once a week with home made board with USBasp.. When I did get similar errors, it was with my connection.

Thanks for your response. I'm using a bought breadboard, with jumpercable connections. I've checked my connections with a multimeter, and they're ok.

Can there be another reason?

Can there be another reason?

Yes, that tutorial is less than perfect, it's missing the supply bypass caps. Try using this better, proven bare bones bootloader guide:

Thanks for your reply, I've tried the guide you've sent, and it worked with the sketches in on this site. I've now a blinking LED on my chip, thanks!
