OrangePi 3 lts / i2C / overlay / armbian-config ?

[kris777]

I tried to set the I2C interface with the armbian-config option but it doesn't work because it writes to the file: armbianEnv.txt ....
overlays=sun50i-h6-i2c0 sun50i-h6-i2c1 sun50i-h6-i2c2
and it didn't work on my OrangePi3LTS and it doesn't start the i2C service on startup? but when I enter it manually:
overlays=i2c0 i2c1 i2c2
then the i2c service works with my 40x2 LCD 🙂 ...is this a bug and if so can it be fixed?
is the option: armbian-config still compatible with my OrangePi3 LTS?

This will be fixed soon.

Having trouble with my klipper accelerometer every time the dtb is upgraded during a update/upgrade.  I made this patch to fix the  spi@5011000 { ...} section:
 

831c831
<                       status = "disabled";
---
>                       status = "okay";
834a835,840
>                       spidev@0 {
>                               compatible = "armbian,spi-dev";
>                               reg = <0x00>;
>                               spi-max-frequency = <0xf4240>;
>                       };
>

And then

dtc -I dtb -O dts -o sun50i-h6-orangepi-3-lts.dts /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dtb
patch -b sun50i-h6-orangepi-3-lts.dtso opi3lts-dtb.patch
dtc -I dts -O dtb -o /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dtb sun50i-h6-orangepi-3-lts.dts

Not sure if this is a sane and safe way to do it, but it works for me at least. Hope it can find it's way in a sane form into a future release. Maybe it's better to do it in an overlay, rather than directly? 

opi3lts-dtb.patch

A little typo in the commands:
patch -b sun50i-h6-orangepi-3-lts.dtso opi3lts-dtb.patch

Should be: 
patch -b sun50i-h6-orangepi-3-lts.dts opi3lts-dtb.patch

it should be .dts and not .dtso, its'n not an overlay. Sorry if that confused anyone.
