But after building it on my Mac with make BOARD=SEEED_WIO_TERMINAL and transferring the resulting firmware.uf2 to the ARDUINO drive on to the Wio Terminal, the Wio Terminal does not boot up. Nothing happens.
Is there any documentation to help with compiling and installing micropython from scratch on Wio Terminal?
My objective is to use a custom library available for micropython.
Have you checked the forum for help? I looks like there are a few discussions on the WIO terminal. micropython forum
I do not have a WIO terminal but have built the XIAO uf2 from with several small mods with no problems. Have you tried the direct the released or nightly build from micropython? uPyrhon for WIO Terminal
