Im new in the husarion community and i use a core2 with a raspberry 4 with the Ubuntu 18.04 + ROS Melodic Image for Rpi.
When i try to load a firmware on the core2 with the stm32loader, every time the error: No such file or directory: ‘/dev/serial0’ happens.
In fact, this file is really missing. I made all steps as decribed in the Core2-Manual and also these ones in the Enviroment-configuration-Descrition. I also considered the advise in https://tinyurl.com/so5oove but it didnt help a lot.
Also the boot/cmdline.text and the boot/config.text are adapted.
What can in do to receive a /dev/serial0 file?
