Arduino Nano Won't Upload?

Projects Programming
1

I'm just a rank novice, trying to get a nano to run, at this point

Just trying to verify my set-up works before trying to actually do anything.

i have the Nano 2.0 connected to a laptop running Win 10, Arduino IDE 18.1 running, correct board and correct port selected, verified from the WIN 10 Device Manager.

On connecting the USB cable , the "L" LED blinks, about 1-1/4 sec cycle, with the LED on about 1/4 sec of that time.

I assume this is the preloaded LED blink program.

So, I tried a VERY simple LED blink program, copied directly from a youtube video.

The program complies fine, but then I get an "Upload Error" message back, and the pre-loaded LED blink program continues as before, confirming the the new program was not in fact uploaded.

I tried two different cables, and then two different USB ports on my laptop: a USB 3.0 (COM3), and a USB 2.0 (COM4), and in each case , the IDE lists the port and allows me to select it, and the ports are correctly listed in the WIN 10 Device Manager, but the program will not upload from either port.

Am I not doing something I need to do, or is it time to start suspecting the Nano?

Welcome to the forum

Your topic was MOVED to its current forum category which is more appropriate than the original as it has nothing to do with Installation and Troubleshooting of the IDE

Which processor have you got selected in the IDE ?

The IDE is showing you all available ports but you don't get to just select any one you want. You have to choose the one that is associated with your Nano.

Unplug the Nano
Look at Device Manager to see the list of COM ports
Plug the Nano into the PC
Look at Device Manager to see what new COM port is listed. That is the port to use.

Ahh, OK, great!

I have watched 3 (apparently useless) tutorials and read another, and none of them gave that procedure.

Thanks.

Since we cannot see your Nano we do not know which boot loader it has. When you select the board, with nano you get an additional choice, if it is not selected select old boot loader, if it is selected select the other. Good Luck!
