Update:
I added these lines from viewtopic.php?p=2322056&hilit=ili9488#p2320285
into my /boot/firmware/config.txt
But then I saw that for my LCD, the touch IRQ is GPIO17, so I changed penirq=17
I rebooted, and touch is working. I can move the cursor in my HDMI display![:)]( "Smile")
But I can't display anything on the 3.5" 480x320 LCD display yet.
I checked the correct parameters: cs=0,dc=24,reset=25
I fixed the incorrect parameter:dtoverlay=ili9341 should be dtoverlay=ili9486
Still no graphics.
Isn't there a reverse reset pin configuration? Is there something else needed for new kernels?
