No serial output with A311D in Pocket Reform

I’ve checked S2 and S1, hooked up as indicated on the board and in the handbook (the handbook is wrong as far as I can tell; pin 1 is GND), and get nothing with a vanilla system image. I verified the serial adapters I’m using are working by hooking them up to one another, and verified the GND pins were indeed GND with a multimeter.

FWIW I spotted the same thing relating to the pins listed in section 8.1.2 Serial Console of the handbook. Unfortunately I’m not getting any serial output on the iMX8MP - were you successful in figuring this out?
