I found this answer How do I make serial work on the Raspberry Pi3 (PiZeroW, Pi4 or later models)

It was very helpful to understand the uart situation on the Pi 4. But when I tried the same config file on a Pi-Zero 2W it did not work. Fair enough it's a different board. However I can't find similar information for the 2W. The reference in the answer only covered up to the Zero and the 4. Where can I dig up how to enable the other uarts on a Pi-Zero 2W. Specifically I'm trying to re-use the hat eeprom pins.

Thank you

It doesn't work because the RP3A0 SOC on the Pi Zero 2 W doesn't have any additional UART.
It has the same peripheral module as ALL early Pi and only has 2 UART

Only the BCM2711 used in the Raspberry Pi 4 Model B, the Raspberry Pi 400, and the Raspberry Pi Compute Module 4 has additional UART.
