You might want to look at this How to get the best out of this forum before you proceed any further.
We only know what you tell us, and without knowing what you have, we don't stand a chance.
NEVER post code as an image it uses too much space and is totally useless for us because we can't try it ourselves.
Look at that link for how to post code correctly. Also post any compiler messages as if they are code.
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
Normally when people say Nano they mean a Nano classic, but there are at least 6 different types of Nano and counting. It seems that Arduino marketing regard the term Nano as a form factor for a number of very different processors.
Your program conpiles OK but for some reason it can't find the avrdude config file.
Which version of the IDE are you using?
Did you recently install a new board or update the IDE?
If your board is a Nano 33 IoT, the Nano 33 IoT is not prgrammed with avrdude. So I suspect that you selected the wrong board under tools/board. You should have the exact version to select from; if not, you will need to install the board package.
