Mavlink OSD is not available in the latest firmware, but old version firmware works well
The air unit can get data from serial, but the ground station(phone) can not display osd data.

I just found solution of using Mavfwd OSD in lasted firmware.
According to this answer from tipoman9.
telemetry_tx and telemetry_rx just copy and rename of wfb_tx and wfb_rx.
In the old firmware, this is how they stared.

So, if you want to use mavfwd. you should
ps
882 root 0:00 wfb_tun -a 10.5.0.10/24
910 root 0:00 msposd -b 115200 -c 8 -r 20

This gonna carsh the lasted Pixlepilot app in your phone. so you need downgrade the pixlepilot

Thank you, this is very helpful to me. But one thing I still don't understand is that the new firmware uses tunneling technology, but it doesn't work for Mavfwd. Is this a bug in the new firmware?
