OttoBlockly Uploading Forever

Other Hardware Robotics

I am using OttoBlockly in my Robotics class. They used to upload ok, but I now have a number of robots that take a very long time in uploading, and end up with this error message:
Error: Command failed: arduino-cli.exe upload --port COM3 --fqbn arduino:avr:nano:cpu=atmega328old sketch/sketch.ino avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x20 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x20 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x20 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x20 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x20 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x20 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x20 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x20 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x20 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x20 Error during Upload: uploading error: uploading error: exit status 1

What do I do to fix this?

You should paste your error report in a < CODE > block for better reading.

The errors look like your computer has not seen your Arduino as inserted.

I see you are using an Arduino nano. You might need a CH340 driver for the USB port to talk to the Nano. Search "arduino install CH340"

I do not know how to select "old bootloader" on the CLI.

Have you asked the Blockly community?

Where would I find the Blockly community?

Ok, I see you provided a link. Thanks. I'll give it a shot.
