I don't know ... I've worked on this since almost a year ...

The DT overlay isn't written to support multiple buses ... But, again, why do you need more than one bus, since OneWire support multiple devices on the same bus ?

/boot/armbianEnv.txt vs build/config/bootenv/rockchip.txt
martinayotte replied to kentAVR's topic in Beginners
If you look at /boot/boot.cmd (which then compiled into /boot/boot.scr), there is a line where /boot/armbianEnv.txt is loaded in memory and then "env import" is executed ... -

Sorry, completely forgot to join, it was too sunny outside ... -
With the help of @megi / @megous , I've now my Pinebook-A64 LCD working. Here is the patch : https://github.com/armbian/build/commit/d49be78b702d7779f78d2655126a56e7f2ea7426

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 ...

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

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 ...

It won't appear as subfolder, but as direct node /dev/spidev0.0 ... Also, check with "dmesg | grep spi" ...

Look at this doc file : /boot/dtb/overlay/README.sun8i-h3-overlays

You've forgot to define "param_spidev_spi_bus" which is mandatory ...

Trying to add gpio-line-names to nanopi duo
martinayotte replied to sgjava's topic in Advanced users - Development
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 (save) pushd cache/sources/linux-odroidxu4/odroid-5.4.y/ git diff arch/arm/boot/dts/exynos5420-pinctrl.dtsi > ~/my-gpio-line-names.patch popd mv ~/my-gpio-line-names.patch patches/kernel/odroidxu4-dev/odroidxu4-add-gpio-line-names.patch -

martinayotte replied to sgjava's topic in Advanced users - Development
Be carefull : phandle can vary between builds, so better use <&pio> and <&r_pio> symbols. 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. -

I would choose to simply add another fragment in the same overlay ...
