I tried to build this board with zephyr 4.0.0 but I get an error:

micropython/ports/zephyr/../../ports/zephyr/machine_wdt.c: In function 'mp_machine_wdt_make_new_instance':
zephyr/include/zephyr/device.h:96:41: error: '__device_dts_ord_DT_N_ALIAS_watchdog0_ORD' undeclared (first use in this function)

      |                                         ^~~~~~~~~

Yes, you will need zephyr mainline to build it now since watchdog timer was not enabled until aftee zephyr 4.1.0 was released.

I do have a CI to build eveey Monday now to avoid this happening in the future: https://github.com/beagleboard/micropython-builder
