Windows 10, D21G board, 24v power supply
When I try to upload a sketch, the com port changes right as the screen flashes on my unit. The IDE (1.8.9) says uploading, the screen pulses, the port changes, and then after a few seconds the IDE reads "Couldn't find a Board on the selected port". If I try to change the port in the IDE and upload again, the console reads "Uploading..." endlessly. This happens with every sketch I try to upload. I cannot attempt to upload another sketch without resetting the unit (double click S1).
Everything was working fine yesterday and I've tried with two different machines and switched out cables.
Hi, can you still upload a sketch when you activate the bootloader manually by double clicking the reset button?
Could you try with the standard Blink sketch (change LED_BUILTIN to 26, the LCD backlight) and send us a screenshot of the console with the error, after enabling 'verbose' mode in your IDE preferences. Please send to firstname.lastname@example.org so we can check what's going on.
