In a previous message, he mentioned he is using the 4" spi version.
I'm assuming that you are trying to get jivelite working. First install jivelite, this will also install the Touchscreen kernel modules. In pCP 3.20, I've started to include the ads7846.ko module that waveshare uses as a touch interface. First, I'm doing this all based on reading, the instructions http://www.waveshare.com/wiki/4inch_RPi_LCD_(A)#Driver I don't have a waveshare screen, so there is no way for me to troubleshoot. You will need to download this to. http://www.waveshare.com/w/upload/7/74/LCD-show-170309.tar.gz Hopefully this is designed for the new 4.9.y kernels. Once extracted, do not run the LCD4-show script......but you need to read what that script is doing. The files of interest are waveshare35a-overlay.dtb -Copy this file to /mnt/mmcblk0p1/overlays/waveshare35a-overlay.dtbo -and /mnt/mmcblk0p1/overlays/waveshare35a-overlay.dtb The next files are the configs for orientation......look at the last lines of the file boot/config-4.txt boot/config-4.txt-90 boot/config-4.txt-180 boot/config-4.txt-270 depending on the orientation (This is the lines from config-4.txt) Add these lines to /mnt/mmcblk0p1/config.txt dtoverlay=waveshare35a dtoverlay=ads7846,cs=1,penirq=17,penirq_pull=2,speed=1000000,keep_vref_on=1,swapxy=0,pmax=255,xohms=60,xmin=200,xmax=3900,ymin=200,ymax=3900 After making the edits, reboot and see if the screen starts up......there is a chance that the screen will stay dark.....the key will be if /dev/fb1 is present on your system, there should also be some messages in dmesg. Lets see how this goes, before moving on. Reminder, if you save files in your home directory, backup before rebooting (pcp bu) /mnt/mmcblk0p1 is persistent, so backup is not needed here. ------------------------------------------------------------------------ paul-'s Profile: http://forums.slimdevices.com/member.php?userid=58858 View this thread: http://forums.slimdevices.com/showthread.php?t=107320 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
