Hi! I made a new one dtb, it seems to work. I not building new device and used spidev from main dtb. It looking great: grecha@orangepi4-lts:~$ sudo dmesg | grep 9341 [ 6.883847] fb_ili9341: module is from the staging directory, the quality is unknown, you have been warned.

If i set overlay, line 23 reg = <0>; then i get [ 2.030154] rockchip-spi ff1d0000.spi: chipselect 0 already in use i understand fdtfile=rockchip/rk3399-orangepi-4-lts.dtb has device spidev reg = <0>; File /boot/dtb/rockchip/overlay/README.rockchip-overlays says "Using chip select 1 requires using "spi-add-cs1" overlay", but i nave not overlay spi-add-cs1. There is an idea to edit rk3399-orangepi-4-lts.dtb - remove device spidev and set reg = <0>; for ili9341, but that is a bad idea, and I'm not sure what will work I would like to make everything just an overlay.
