3.5“ TFT (40 pin header)

I want to display and operate the UP board with a Touch Panel Module of 3.5 “or less, so I attached
Adafruit's PiTFT Plus 480x320 3.5“ TFT (40 pin header) verified by
(https://wiki.up-community.org/TFT_Display_HATs)
And writen
“The ubilinux kernel includes the fbtft driver modules, enabling a selection of small TFT displays”
So I installed ubilinux on the UP board
(https://wiki.up-community.org/Ubilinux)
and Installed Adafruit_GPIO library
(https://wiki.up-community.org/Adafruit)
Next I executed as
(https://wiki.up-community.org/TFT_Display_HATs)
sudo modprobe fbtft dma = 0
sudo modprobe fbtft_device custom name = fb_hx8357d rotate = 270 speed = 42000000 buswidth = 8 bgr = 1 gpios = dc: 25 busnum = 2
sudo apt-get install fbset
con2fbmap 1 1
However, the display remained black, and when I rebooted, errors were displayed for a few seconds (like photo) .
After that, the screen remains black and nothing is displayed.
I tried two UP boards and the errors differ a little.
What am I missing?

You have to get to the bottom of the tutorial to enable the screen to be used by X server and desktop environment.
From what I read you are missing the steps from test your display towards the end.
