I have recently bought RK3399-PC and tring to boot ubuntu. But after flashing the ubuntu into the SD card, I am not able to follow the steps given in the link http://wiki.t-firefly.com/en/ROC-RK3399-PC/linux_sdk.html#. When I try to compile Environment from the following link http://wiki.t-firefly.com/en/ROC … compile-environment it diplays error “aarch64 file is obsoelte or command not found”.
I have included Expansion board to the development board and has flashed ubuntu from the following link https://drive.google.com/drive/f … LY0DG_BLx94eAeArvwI Are there any additional libraries that I need to install before compiling ubuntu firmware? Could you guide me in completing the bootup?

Hi, welcome to the forum.

The “sudo apt-get …” command is meant to run as a big long line.
But copy and paste will result in multiple lines.

We’ll fix the doc.
