How to upload example code in Windows

I’ve built the AP_Rangefinder example code in my WSL2 but I’m unable to upload it to my pixracer.
To build it I’ve run:

./waf build --targets examples/RFIND_test

Then I’ve copied the binary RFIND_test to a folder in my Windows system and tried to use Mission Planner’s “Load custom firmware” option to upload the firmware but I got the error below.
error_apm

Is there another way to upload those example code binaries from Windows? (command line or other)

Update to the latest MissionPlanner Beta release.

Thanks for the tip, very much appreciated!
