BPI-M5 not working with SPI TFT display board

Hello ! I bought some time ago a 3.5 inch TFT display (http://www.lcdwiki.com/3.5inch_RPi_Display) and I have followed the installation instructions to be used in my BPI-M5 however the TFT display is always just plain white.

Before installing the display drivers, I ran an apt update and upgrade commands and rebooted. The installation process was simply cloning the repo and running the script:

git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
sudo ./LCD35-show

Some info about my system (Im using the Ubuntu Mate image from the BPI wiki)

[email protected]:~$ uname -r
[email protected]:~$ uname -a
Linux bananapi 4.9.241-BPI-M5 #2 SMP PREEMPT Mon Jun 21 16:29:40 HKT 2021 aarch64 aarch64 aarch64 GNU/Linux

After running sudo ./LCD35-show for the first time, the connected HDMI display stopped working but the TFT screen was blank. I noticed in the log there was a cmake error while running the script:

include <bcm_host.h>: No such file or directory

I found the solution (not 100% sure since it’s for the RPI) in this thread of stackoverflow with the command sudo apt-get install libraspberrypi-dev (I didnt install raspberrypi-kernel-headers since it was not found)

I also noticed I was getting these errors in the script:

grep: /boot/cmdline.txt: No such file or directory
cp: cannot stat '/boot/cmdline.txt': No such file or directory

So I manually made created an empty file in the boot partition cmdline.txt. However I checked later and there was nothing added to this file (?)

This is the output Im getting now from the script:

reboot now

I tried running the script, rebooting several times, connecting and disconnecting the HDMI, running the ./LCD-hdmi script and then the ./LCD35-show script but nothing have worked so far, at one point after running ./LCD35-show the HDMI display showed the desktop environment again (it was reconnected somehow) which it’s still somewhat confusing.

# uncomment if hdmi display is not detected and composite is being output

# uncomment to force a specific HDMI mode (this will force VGA)

# uncomment to force a HDMI mode rather than DVI. This can make audio work in

Some notes

  • apt upgrade shows all packages updated
  • I checked the pins and they seem to be the same as in the RPI, so I connected the TFT screen in the same manner
  • I’m using a “fast charge” phone charger which I guess gives enough power. It states “5V 2A 10W or 5V 6A Max 30W”
  • I have no other RPI/BPI to check that the display is working correctly
  • Everytime I ran the LCD35-show script it seems to try to install the xserver-xorg-input-evdev package (and succeed):

Update I also tried with the official preconfigured image of Ubuntu Mate (32bits) from here http://www.lcdwiki.com/3.5inch_RPi_Display with no luck
