I have an issue with my raspberry pi 3 B+ running on Raspbian. Indeed just after trying to set up a 4 inch HDMI LCD screen in the following way :
-Adding these lines in the config.txt
Hdmi_group = 2
Hdmi_mode = 87
Hdmi_cvt 480 800 60 6 0 0 0
Dtoverlay = ads7846 , cs = 1 , penirq = 25 , penirq_pull = 2 , speed = 50000 , keep_vref_on = 0 , swapxy = 0 , pmax = 255 , xohms = 150 , xmin = 200 , xmax = 3900 , ymin = 200 , ymax = 3900
Display_rotate = 3
-git clone https : //github.com/waveshare/LCD-show.git
-and running the file LCD4 - 800x480 - show
At this point the board reboot and since then my problems started :
The boot start correctly until the last line on screen :
Code: Select all
Starting Terminate Plymouth Boot Screnn...
After that I'm stuck with that screen :
And the red and green LEDs are blinking.
It's a problem really simillar to this one :
But no answers are working for me.
Personnaly I think it's a problem with the memory during the installation of the LCD driver but I have no idea how to solve it. I really need to get it working without wiping all the memory, beacause I have really important files for a project inside.
Thank you for the help!
