sketch uploads but won't run

Using Arduino Avrdude, stk500, Bootloader issues
1

hi,

Using latest IDE and created a simple sketch to run on a Nano.
The sketch compiles with no errors.

Had to select 328P (Old Bootloader) and it did seem to upload.
When I tried to query the 'Get board info' I got
BN: Unknown board
VID: 1A86
PID: 7523When
it then says load a sketch and try again.

I plug the Nano into the circuit and it doesn't function. is it a Nano hardware problem?

Using W10 latest build.

Please do this:

  • File > Preferences > Show verbose output during: > compilation (uncheck) > upload (check) > OK
  • Sketch > Upload
  • After the upload fails you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
  • Paste the error messages in a reply here USING CODE TAGS (</> button on the toolbar).

With the popularity of "derivative" board designs, it is not expected that all boards are "known" to the IDE.
This is not really an error; if things are otherwise operating normally, you should be able to ignore it.
