Kernel version 4.19.13-sunxi does not accept param_w1_pin=

As I said in the other thread, it is not the kernel that manage those DT parameters, it is u-boot responsible to load them, so, we need to see in early u-boot log (before kernel started) if the fixup.scr apply succeeded or not .

You need USB-TTL Serial dongle to watch those early logs ...

I successfully tested rotary encoder device overlay with armbian-add-overlay.

Source is here https://github.com/teknoid/dac/blob/master/misc/gpio-rotary.dts

@zador.blood.stained you may add this to the example directory on github.

Where do  i find the corresponding driver on the kernel source code , pertaining to the following dts file:

I had submitted a PR last year that was committed to the tree at https://github.com/armbian/sunxi-DT-overlays but this doesn't seem to have made it to the mainline nor is it included in any pine64 pre-built kernels.  It is a very simple one-line correction from 

 

 

For now I've been using a local user patch when rebuilding kernels.  Would I need to submit a separate PR for the linux mainline as well?

 

Or would a PR to add a bundled patch in the armbian build tree be better/preferred?

The sunxi-DT-overlays is some kind of backup repository, but the real place that you fix should be in the patches, in the present case here :

https://github.com/armbian/build/blob/master/patch/kernel/sunxi-dev/general-sunxi-overlays.patch#L5071

Feel free to submit another PR for that file, we will merge it quickly ...

[windysea]

Thanks!

 

I've submitted the a PR with two separate commits, one each for -dev and -next, with the exact same change.  I didn't know if you would accept PRs on -next and meant to create two PRs but the second commit was merged with the first PR that had already been submitted. . .

Hi,

can anybody help me adapt this overlay to H5 cpu (Pi PC2) ? I experiment myself and make this workable for DS3231 but it is still registered as RTC1.

I change:

- rtc0 = "/soc@01c00000/i2c@01c2b400/ds3231@68"; to rtc0 = "/soc@01c00000/i2c@01c2b000/ds3231@68";  ( I2C0 = i2c@01c2b000 )

- target = <&i2c1>; to target = <&i2c0>;

 

As I said, it works, it register DS3231 at boot and it works include HWMON but it is still as RTC1.

Have anybody idea how to set it and replace RTC0 ? (RTC0 on H5 is on 1f00000)

And can anybody explain me a bit what is meaning with addresses "/soc@01c00000/rtc@01c20d00" ?

Kernel:  4.19.38-sunxi64 #5.86 SMP

 

Thanks

Hello,

 

I have found an issue with the audio device on allwinner H2+/H3 boards. The internal audio DAC works just fine on Armbian Stretch, but on Armbian Buster the audio device appears as mono-only in pulseaudio. When trying to run 'speaker-test -c 2' the audio channels appear to be flipped?

I figured this is an issue with the device tree? This seems to be a common issue: 

my post:

This issue affects the Buster and Bionic builds. I have a few extra SD cards, so I can test stuff out or give you any required console outputs.

Were you using same kernel on Stretch and Buster? And which. "Buster" and "Stretch" tells us little to nothing.

hello, I am running armbian focal on Bananapi M64. When I was on kernel 5.4, I can get ir device named "sunxi-ir" under /dev/input/event1 by running getevent (https://github.com/ndyer/getevent), however after I upgraded kernel to 5.7 the ir device is no longer available. I am not sure if its a problem with kernel or device tree. I tried to modprobe sunxi_cir with no luck.

Hello!

Using Debian packaged by the Olimex people (not Armbian, see their image here) I tried your 1-wire DTS plugin but it did not work.

Trying to understand why, I contacted the linux-sunxi developers who considered that your DTS plugin is outdated.

See the discussion here.

 

Their suggestions resulted in this DTS file that should work also on Armbian.

I did not make a pull request towards your overlay repository as I am not able to update the param_w1_pin_int_pullup setting code in the sun50i-a64-fixup.scr-cmd file.
