i've been trying ages to get this screen to work with picoreplayer without succes, can anyone help...
this is what i ve tried:
sudo mkdir -p/etc/X11/xorg.conf.d
sudo cp ./waveshare35a-overlay.dtb /overlays/
sudo cp -rf ./etc/X11/xorg.conf.d/99-calibration.conf-35 /etc/X11/xorg.conf.d/99-calibration.conf
sudo cp -rf ./usr/share/X11/xorg.conf.d/99-fbturbo.conf /usr/share/X11/xorg.conf.d/
sudo cp ./cmdline.txt /
sudo cp ./inittab /etc/
sudo cp ./boot/config-35.txt /boot/config.txt
filetool.sh -b
screen stays white.
tried it with raspbian and all is working
patrikg:
What kernel module is loaded in raspbian to support the display.
lsmod
You may need to load that in picore.
madmax6:
i don't know what kernel module is loaded, this is the site of the manufacture:

Hi madmax6

Did you update your filetool.lst file first? Were the files you copied restored after you rebooted?

I don't think you can use a modified /etc/inittab using the backup/restore mechanism. I'm pretty sure that by the time
the inittab is restored, the original one from the initrd has already been run.

Look this thread, I've wrote there everything how to bring the screen working:

The first what you need are kernel modules, something like tft.tcz. Than you need modify cmdline.txt. You need to modify it manually, don't use that one from Rasbian. The same with the config.txt.
You don't need inittab, forget it.
