nRF52840-MDK micropython/circuitpython flash succesful but no LED or REPL

I’ve tried flashing with all builds of circuitpython and micropython. The only one I got working was the prebuilt makerdiary hex from the nRF52832-mdk wiki. I am able to activate/deactivate bluetooth etc. with this build, but I fear that many features will not work as it is not the correct board it is built for.

I’ve flashed with both the drag-n-drop method and pyocd, neither works for the builds I’ve tried.
