OpenThread daemon fails to run whenever using the nRF 52840 DK development board but works fine when using the nRF 52840 Dongle. I reinstalled it multiple times and started from scratch with so many tweaks but couldn't figure it out.
Default OTBR Agent: cat /etc/default/otbr-agent
# Default settings for otbr-agent. This file is sourced by systemd # Options to pass to otbr-agent OTBR_AGENT_OPTS="-I wpan0 -B wlan0 spinel+hdlc+uart:///dev/ttyACM0 trel://wlan0" OTBR_NO_AUTO_ATTACH=0
I can confirm the development board appears in the same port as shown above. ls /dev/ttyA*
/dev/ttyACM0 /dev/ttyACM1 /dev/ttyAMA0
I tried manually enabling the OpenThread daemon like the following but no luck.
sudo otbr-agent -I wpan0 -B wlan0 spinel+hdlc+uart:///dev/ttyACM0 trel://wlan0 -v

And, here's the otbr-agent status: service otbr-agent status

Hardware
- Raspberry Pi 4 (4Gb)
- nRF 52840 DK
Software
Does anybody have any idea what's going wrong? It's very odd since nRF 52840 Dongle works fine with the same sample template with the following build flag added.
-DOVERLAY_CONFIG="overlay-usb.conf" -DDTC_OVERLAY_FILE="usb.overlay"
