Successfully got XH-WB3S (BK7238) with driver AHT2X and AHT30 sensor up and running.
Then I wanted to try some power saving, with this startup:

backlog startDriver SSDP; startdriver AHT2x 7 8 1 2; PowerSave 1

That didn't go well. The BK7238 is not online anymore.
How to recover? Connect to UART and reflash? Any simpler method?
