Hi
I know there are hundreds of post concerning this error message, and I have tried several solutions without any luck (including changing COM port number, switching ATmega328P processer between new and old). Hope some one can help.
I'm using a Nano, IDE 2.3.2, and Windows 11. No other applications are running, and IDE is only running one sketch at a time. No other USB devices are connected to the computer. Have tried several sketches that all compile successfully.
When I start IDE, I can upload a sketch one time (and the sketch works). When I try to upload a second time, I get the following error message (verbose output):
Sketch uses 2302 bytes (7%) of program storage space. Maximum is 30720 bytes.
Global variables use 190 bytes (9%) of dynamic memory, leaving 1858 bytes for local variables. Maximum is 2048 bytes.

Failed uploading: uploading error: exit status 1
Sometimes I can unplug the Nano, reconnect, and make again one upload. Uploading after this, gives the above error message. Sometimes I have to restart IDE. Other times waiting 10 minutes has the same effect. Either way I can only upload once, which makes experimenting with the Nano virtually impossible.
When the upload works the verbose output message is:
Sketch uses 2302 bytes (7%) of program storage space. Maximum is 30720 bytes.
Global variables use 190 bytes (9%) of dynamic memory, leaving 1858 bytes for local variables. Maximum is 2048 bytes.
