Using M.2 5G Modem Addon Board (M0090) on voxl2 , can not found the /dev/ttyHS2 device

Hi,
I am following https://docs.modalai.com/voxl2-external-flight-controller/
to connect external flight-controller.

Using M.2 5G Modem Addon Board (M0090)
The VOXL2 (M0054) can have the M.2 5G Modem Board Addon attached, which exposes a UART on M0090 - J9 that is accessible in VOXL2’s application processor as /dev/ttyHS2.

I can not found /dev/ttyHS2 device. How can I enable this device ?

Please assist.

Hi @Cheng-Sheng-Weng ,

Can you run voxl-version and paste info here? That device should be available as of system image 1.3+

If you are on a 1.2.x image, please upgrade to the VOXL2 Platform 0.9
from https://developer.modalai.com/ and install following https://docs.modalai.com/platform-releases/#install
