    The user can control via commands:

    armsom@armsom-w3:/# sudo su
    root@armsom-w3:/# echo timer > /sys/class/leds/blue:status/trigger
    root@armsom-w3:/# echo activity > /sys/clas

    RTC​

    • The ArmSoM-W3 is equipped with an RTC IC hym8563.
    • First, insert the RTC battery to power the RTC IC.
    • Note that we should keep the RTC battery in the RTC connector and confirm the rtc hym8563 device has been created
    armsom@armsom-w3:/#  dmesg | grep rtc
    [    6.407133] rtc-hym8563 6-0051: rtc information is valid
    [    6.412731] rtc-hym8563 6-0051: registered as rtc0

    • Locating rtc0, then use the following commands to set system time and sync to rtc0. 
    armsom@armsom-w3:/# hwclock -r

    armsom@armsom-w3:/# hwclock -w
    armsom@armsom-w3:/# hwclock -r
    armsom@armsom-w3:/# poweroff
    • Removing RTC battery, after 10mins or longer insert battery and boot ArmSoM-W3, check if RTC is in sync with system clock 
    armsom@armsom-w3:/# hwclock -r

    Fan​

    The ArmSoM-W3 is equipped with a 5V fan, using a 1.25mm connector

    M.2 Interface​

    The ArmSoM-W3 provides two M.2 connectors:

    • There is an M.2 E Key connector on the front of the board with a 2230 mounting hole, providing PCIe 2.1 single-channel, USB, SATA, SDIO, PCM and UART signals, supporting standard industrial M.2 WiFi 6 modules.
      ArmSoM recommends using RTL8852BE, AP6256. Installed in the ArmSoM-W3 M.2 E slot and then it can get online after wifi setup.

    Use v4l2-ctl for image capture 

    armsom@armsom-w3:/# v4l2-ctl -d /dev/video11 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=3 --stream-skip=60 --stream-to=/tmp/cif73.out --stream-count=3 --stream-poll

    Use gst-launch-1.0 for direct video recording 

    armsom@armsom-w3:/# gst-launch-1.0 v4l2src device=/dev/video11 ! video/x-raw,format=NV12,width=3840,height=2160, framerate=30/1 ! xvimagesink
