BOOTLOADER

Hello,

I am trying to burn boot loader on arduino promini3.3V using arduino uno. I have connected as follows:

Promini-uno power – 3.3V ground – GND MOSI – D11 MISO – D12 SCK – D13 reset – D10

I also selected programmer as arduino as isp and changed the board to promini. com ports are fine too.

it says: burning bootloader to i/o board and it doesnt burn at all.

Can someone please tell me what the problem might be?

Thank you

Use Nick Gammon's bootload installer sketch instead. http://www.gammon.com.au/bootloader

And don't crosspost. One topic, one discussion. Have a little patience.

Thank you.

I apologize for being impatient.

If it did, you wouldn't be posting here. This tells us literally nothing.

What is the error message?

Do you have the ArduinoISP sketch loaded onto the UNO?

Hello,

The problem was with the Uno. I changed the Uno and now it worked.

Thank you
