Dasduino CORE upload fails with stk500_recv() or upload.tool.serial error

Customer:

I need help with proper installation instructions for the Dasduino CORE microcontroller.

I installed the driver from https://soldered.com/learn/ch340-driver-installation-croduino-basic3-nova2/ and installed Dasduino AVR boards by soldered in the Arduino IDE boards manager.

Version 1 produces the error: avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xd5

Version 2 produces the error: Property ‘upload.tool.serial’ is undefined.

Trebam pomoć tj. točne instrukcije za instalaciju Dasduino core mikrokontrolera.

Dakle instalirao sam driver (https://soldered.com/learn/ch340-driver-installation-croduino-basic3-nova2/) i u Arduino IDE boards manageru instalirao Dasduino AVR boards by soldered.

Verzija 1 izbacuje error: avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xd5

Verzija 2 izbacuje error: Property ‘upload.tool.serial’ is undefined.

Soldered Support:

The board definition should be Dasduino CORE under Dasduino AVR Boards.

Do you have anything connected to the board? External components connected to some pins can prevent code upload. Try taking just the board with nothing attached, connect it via USB, and upload an empty sketch.

If that doesn’t work, try lowering the upload speed (also in the tools menu) to 115200.

Board definition bi trebao biti Dasduino CORE pod Dasduino AVR Boards. Šaljem screenshot:

Imaš li nešto spojeno na pločicu? Vanjske komponente spojene na neke pinove bi mogle spriječiti upload koda. Probaj samo uzeti board bez ičega, spojiti ga preko USB-a i uploadati prazan sketch.

Ako ni to ne radi, probaj smanjiti upload speed (isto u tom tools izborniku) na 115200.
