    So while i`m not familiar with the the details of the display init i assume this is not the display but the gpu / drm driver crashing.

    I've tried for months to clarify the reason of such issue ...

    My last working kernel was 5.7.6, and the issue appeared as soon as 5.8.0, I've done "diff" between both branches and I still didn't figured out the glitches ...

    seem to make some trouble

    It seems that NanoPi K1 Plus is using rtl8189 WiFi ... Right ?

    Driver is broken in 5.11, I'm working on it with other guys, I'm using OPiPC+/OPiLite/OPiPlus2E.

    In the mean time, if you don't need WiFi, disable the module :

    mv /lib/modules/5.11.1-sunxi/kernel/drivers/net/wireless/rtl8189fs/8189fs.ko /lib/modules/5.11.1-sunxi/kernel/drivers/net/wireless/rtl8189fs/8189fs.ko-disabled

    I try to communicate on UART3

    Can you check DT if pinctrl-0 is present in UART3 node ?


    You can verify using this :

    ll /proc/device-tree/soc/serial@5000c00

    (In my old 5.9 build, I see that they are missing and only UART0 has its pinctl-0 handle.)


    If missing, you can decompile DTB into DTS, edit DTS to add "pinctrl-0 = <phandle>;" where phandle can be found in "uart3-pins" node ...

    This is the step I'm missing.

    I'm not understanding exactly.

    Maybe because I've always producing patches manually ...

    Here is a summary of how I would do it :

    (edit the file to add "gpio-line-names" manually)
    nano cache/sources/linux-odroidxu4/odroid-5.4.y/arch/arm/boot/dts/exynos5420-pinctrl.dtsi
    pushd cache/sources/linux-odroidxu4/odroid-5.4.y/
    git diff arch/arm/boot/dts/exynos5420-pinctrl.dtsi > ~/my-gpio-line-names.patch
    mv ~/my-gpio-line-names.patch patches/kernel/odroidxu4-dev/odroidxu4-add-gpio-line-names.patch

    each pinctrl using phandle to identify

    Be carefull : phandle can vary between builds, so better use <&pio> and <&r_pio> symbols.

    So next question is how do I make this part of build process

    As I said earlier, append you overlay code in some new board specific patch such as ./patch/kernel/sunxi-dev/nanopi-duo/board-h2plus-nanopi-duo-add-overlay.patch which will also provide change to arch/arm/boot/dts/overlay/Makefile.
