Other RP2040 boards • Re: RP2354B not showing up as serial after successful .uf2 write

For Pico SDK builds you need to specify USB serial is used in 'CMakeLists.txt'. No idea how or where to do that for Arduino IDE or VS Code builds.

That is also my understanding. I ensured was enabled when testing for serial connection, I am unaware of any additional flags I would need to raise.
I have not linked any libraries other than pico_stdlib, however I do not believe that could be the problem as the code functions just as expected on a regular RP2350 board.
