Hi, I'm trying to run a tutorial that does OpenThread process with nRF52840-DK.
The URL for reference is below.
https://openthread.io/codelabs/openthread-hardware?hl=ja#0
I'm doing it in order from the first step, but I get an error at the "Start OpenThread Daemon" step and can't proceed.
In addition, I confirmed that the nRF52840-DK was detected as ttyACM0 just before.
--- log start --------------------
sudo ./build/posix/src/posix/ot-daemon -v 'spinel+hdlc+uart:///dev/ttyACM0?uart-baudrate=115200'

The execution environment is below.
OS Name: Ubuntu 22.04.2 LTS
OS Type: 64-bit
SEGGER J-Link: V7.88e 64-bit DEB Installer
nRF5x Command Line Tool: V10.21.0 Linux x86 64
ARM GNU toolchain: gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
Are there any possible solutions for this situation?
