Arduino Nano cannot upload sketch

Question

I have tested a circuit with an arduino nano. Afterwards I created a pcb with the ATMega328 on it and with the exactly same circuit. If I try to upload my sketch now I get this Error msg. Thank you for your help in advance.

avrdude done. Thank you.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. `

Answer 1

Try the following, this should work.

Remove connections to the board pins, especially the 0 (RX) and 1 (TX) digital pins while uploading.

The above thing worked for me, after uploading again make connections to those pins.

If this is not helpful check the following :-

1. Check your board and port selections :- In the top menu bar, make sure the correct board is selected in Tools > Board, and that you’ve selected the right port in Tools > Port. Try disconnecting and reconnecting your board if you’re unsure which port is being used (close and reopen the Port menu to refresh the list). For more information, see Select the right port and board.

2. Check your sketch for errors :- Click the Verify button Verify button to compile your sketch without uploading it. If you still get an error, see Compilation errors when uploading.

3. Check your connections :- Your board needs to be connected with a data USB cable (charge-only cables will not work). Make sure the cable is fully inserted in the port on each end. Try a different USB cable, and avoid hubs and other adapters if possible. Remove connections to the board pins, especially the 0 (RX) and 1 (TX) digital pins.
