@StuxNet I am using RPI 3.2 inch LCD from waveshare ( http://www.waveshare.com/3.2inch-rpi-lcd-b.htm ) which has similar pin count as required in orangepi zero, so I plugged LCD directly using bugstrip as shown in https://kaspars.net/blog/linux/spi-display-orange-pi-zero. For LCD interfacing I have attached the snapshot of my board for your reference. To get the Desktop environment on screen, I have followed the reference https://4pda.ru/forum/index.php?showtopic=750921&st=1800#entry58412437 LCD supports touch but as far as I know legacy kernel does not support LCD & touch simultaneously (correct me if I am wrong), so I am using only LCD, no touch Screen lock happens sporadically. I have attached dmesg & Xserver log for your diagnostic Xorg.0.log dmesg.log

Hi, I am using orangepizero with Armbian_5.30_Orangepizero_Ubuntu_xenial_default_3.4.113 ubuntu server image. I have also installed mate desktop environment to enable my desktop on my waveshare 3.2 LCD. Now the issue is my desktop freezes in my LCD couple of minutes after boot. I have used heatsink with fan, armbianmonitor show operating temp 40-50 deg cel and cpu load when i run any application 30-40%. I observed one thing when my desktop freezes in my LCD, i can access my orangepi with VNC as separate session where i can see my desktop and perform any task flawlessly without any freeze. Any help here?

Just to add i am viewing my desktop in Waveshare 3.2 LCD connected to orangepizero board. It looks like LCD fails to refresh the screen after some time but am not sure with this..

Hi All, I am also facing issue on similar lines on my orangepi zero but not sure with the probable cause. My desktop freezes couple of minutes after boot. I am using heat sink with fan, armbian monitor shows hw temp variations of 45 - 55 deg celsius. I have installed Armbian_5.30_Orangepizero_Ubuntu_xenial_default_3.4.113 along with mate GUI environment as guided in https://4pda.ru/forum/index.php?showtopic=750921&st=1800#entry58412437 When Desktop freezes, i try to run other application from ssh it works flawlessly like i played audio file. Anyone help me to fix this issue

@sov1178 ads7846.ko enlisted in both the files modules.dep kernel/drivers/input/touchscreen/ads7846.ko: modules.order kernel/drivers/input/touchscreen/ads7846.ko still modprobe command fails to load ads7846

@sov1178 Still facing same issue post running command sudo depmod -a

Hi, As suggested, I have followed the following steps: 1. Pasted the pre-compiled touch driver ads7846.ko at /lib/modules/3.4.113-sun8i/kernel/drivers/input/touchscreen 2. Modified the /boot/script.bin with the suggested configuration changes for OPI one to enable touch "ads7846" module 3. Reboot Post reboot when i run command sudo modprobe ads7846.ko -f, I am getting error "modprobe: FATAL: Module ads7846.ko not found in directory /lib/modules/3.4.113-sun8i" Also I have checked the kernel logs, it shows : [ 3.996407] fbtft_device: SPI devices registered: [ 3.996428] fbtft_device: ads7846 spi0.0 1500kHz 8 bits mode=0x00 [ 3.996439] fbtft_device: 'fb' Platform devices registered: [ 3.996511] fbtft_device: Deleting spi0.0 [ 3.996697] fbtft_device: GPIOS used by 'flexfb': [ 3.996707] fbtft_device: 'dc' = GPIO3 [ 3.996715] fbtft_device: 'reset' = GPIO0 [ 3.996722] fbtft_device: SPI devices registered: [ 3.996733] fbtft_device: flexfb spi0.0 3200kHz 8 bits mode=0x00 But touch is not working .. kindly suggest further

@Mike R9FT I am trying to enable touch for Waveshare 3.2 LCD with OPI one which has xpt2046 touch controller. I am using Armbian_5.30_Orangepione_Ubuntu_xenial_default_3.4.113_desktop. I didn't get with modifications required in the ads7846.c in the kernel source. Kindly guide me with the step by step procedure to modify the source file for waveshare 3.2 LCD. LCD pin details http://www.waveshare.com/3.2inch-rpi-lcd-b.htm

I am using Armbian_5.30_Orangepione_ubuntu_xenial_default_3.4.113_desktop for orangepi zero and am able to drive the LCD in GUI mode. I have tried https://github.com/Tomasz-Mankowski/ADS7846-X11-daemon to install the touch driver but i dont see my touch working. Do i need to make any change in the hardware pins?
