Cannot Upload Sketch to Arduino R4

Hello All,

I have a brand new Arduino R4 Wifi with nothing plugged into it and connected to my computer. I have the correct COM and BOARD selected, and whenever I try to upload I get the same error:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x85

I have tried basic steps of unplugging/replugging, restarting computer, etc. My coworker has the exact same computer and when he plugs in he can upload to the board fine. I uninstalled and reinstalled Arduino IDE 2.3, and now do not know what to try next.

I did notice my coworker has different programmer names under tools > programmer than I do

Did you select Uno as the board or Uno R4 WiFi?

If you don't have the Uno R4 WiFI option, you will need to install the board package.

Hello, it is there and I have it selected

That's an Uno WiFi, not an Uno R4 WiFi.


I've moved your topic because you're not using IDE 1.x; there is a dedicated section for IDE 2.x. But the best place for board detection and upload problems is Avrdude, stk500, Bootloader issues - Arduino Forum where it's now.

I didn't realize they were different! Downloaded the right board and it worked. Thanks!
Easy fix
