Thanks a lot, It works!
I've bought the orange pi zero 2 rencently, with also the board version v1.5, but in my case it seems that "pull PC5 to GND" is still needed, which is written at wiki:
I use the latest Armbian IoT based on Ubnutu:
So it may have some variant?
Whatever, as it says: "pull PC5 to GND", I used a 2pin jumper(header) to shortcut the pin13(PC5) and pin14 rather than pin13 and pin9, since they are next to each other, and it works! 🙂 So I posted here in case someone runs into the same issue.
