Arm-none-eabi-g++: error: 4: No such file or directory

Per Maximillian Gerhardt’s updates, PlatformIO now supports Arduino UNO R4. However, I continually get the error in the title of this post after following all the instructions in Maximillian’s post.

I’ve updated PlatformIO to the latest build as requested.

I’m using Win10.

Per cannot open source file "bsp_api.h" (dependency of "Arduino.h") · Issue #1 · maxgerhardt/platform-renesas · GitHub, let’s discuss this in Issues · maxgerhardt/platform-renesas · GitHub.
