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)

pi@bananapi:~$ uname -r
pi@bananapi:~$ 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 the following to adjust overscan. Use positive numbers if console

# uncomment to force a console size. By default it will be display's size minus

# 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

# uncomment to increase signal to HDMI, if you have interference, blanking, or

# uncomment for composite PAL

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):
The following NEW packages will be installed:

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

did it work in the end? if yes please tell me how.

this is only for rpi board, m5 is totally different hw and sw, refer to https://github.com/Dangku/amlogic-linux/blob/odroidg12-4.9.y-c4-m5/arch/arm64/boot/dts/amlogic/overlays/bpi-m5/waveshare_tft35c_lcd.dts and modify for your panel

do you know how to make the display for bpi-m64 for RPI LCD 3.5?
