At the same time, it is impossible to enter any messages into the terminal. In this connection, I do not know why the system does not work with the new pbf file. And also there is a difficulty with Step Step 7.1 – Configuring Buildroot. Namely, trying to save the configuration the program seems to hang and from it you can not go out except if you close the terminal.
