OrangePi ubuntu focal desktop dtb file issue (is OrangePi supported again?)

OPUser · February 25, 2021

Hello

After a couple of years, I took my "ancient" OrangePi board and found it working well with Ubuntu 18.04 (kernel 3.14.113). And I even did distr update to 20.04. So HW is ok.

I found that Armibian support status of OrangiPi is changed to "Supported" and decided to try the latest image with modern kernel "Armbian_21.02.1_Bananapi_focal_current_5.10.12_desktop.img.xz" (shared image between OrangePi and BananaPi).

XFCE desktop was loaded but USB was not working. And that was the known mismatch between OrangePi and BananaPi HW conguration. So I updated "/boot/armbianEnv.txt" with "fdtfile=sun7i-a20-orangepi.dtb".

But after that video became OFF and board is working only as network remote station.

That makes me think that supplied "sun7i-a20-orangepi.dtb" is incorrect. Does it make sense?

(if I remove "fdtfile=sun7i-a20-orangepi.dtb" video is working again but USB is not)

Where can I get an older version of "sun7i-a20-orangepi.dtb"? (old bin/fex file in old OragnePi images was ok)

P.S. Does Armbian_21.02.1 supports HW video acceleration with 5.10 kernel? And how to make WiFi working? (ifconfig do not show WiFi interface)

Thank you

I have compared dts files and found that some devices were disabled

Spoiler

I switched them to "okay" but it didn't help to enable HDMI monitor output with OrangePi dtb file

zador.blood.stained, I saw you had a great contribution to Armbian on such subjects, can you comment please what could be wrong with stock OrangePi dtb file?

IIRC we have (had?) some bug related to A20 / LK5.10.y / HDMI out. Try build image from sources.

Those DTs are maintained upstream, but not sure if there were any changes for years. Some properties could also become obsolete in the meantime ... Also try this way: armbian-config -> system -> hardware and enable all USB ports.

Could be more than one reason:

- keeping wifi drivers nobody maintains aligned with modern kernel. Require constant rework - just few recent commits on the topic:
https://github.com/armbian/build/commit/ec36591108c6b96faec3c74c5421faf05a5060bb

https://github.com/armbian/build/commit/d28c170a2354bfc0413ee8594ab2e690259fe2b9

https://github.com/armbian/build/commit/03e4f604d3ee991183840ff7a3c0959be1e28637

- DT bits for Orangepi wifi are not present in Bananapi DT

Try not to associate question to persons. This is forum. People help if they can and have time ...

Kernel driver is present, but we don't have click and play experience. I don't deal with this.

I enabled OrangePi config and built two focal desktop images. Image with kernel v5.10 has the same problem with dtb config (no USB, no HDMI)

while image with v5.4 works good. WiFi is connected to USB so that explains issue with WiFi on kernel v5.10

Got it! However, both BananaPi and OrangePi have few changes per year. But, perhaps, something was broken between v5.4 and later version like v5.10

Will try to check this, thank you. But it is not working on v5.4 out-of-the-box

armbian-config for OrangePi doesn't allow to enable it - USB is missing there (due to missing overlays in dtb/overlay folder?)

Here are some notes of possible improvements

- it will be good to put "boot.cmd", "boot.scr", ArmbianEnv.txt and ".next" inside some Armbian debs, if lost they can be taken only from Armbian image (if I'm not mistaken)

- linux-u-boot-legacy-orangepi_21.05.0-trunk_armhf.deb and linux-u-boot-current-orangepi_21.05.0-trunk_armhf.deb are in conflict?! I had to install u-boot manually

sorry it is in Russian, but it says about an error and packets conflict

- A minor cosmetic thing. Adding fdtfile=sun7i-a20-orangepi.dtb to ArmbianEnv.txt of BananaPi image doesn't make a "full" conversion to OrangePi, how to proper set new BOARD_NAME to correct name on welcome screen?

If you report troubles with self build image not many people will listen. Self build images are officially not supported since they are build from a development environment, unknown upstream quality, nobody test features and anyway we can't afford dealing with "customers" in real time. Strictly speaking only digitally signed images are a subject of our interest. Limited with our private time! Even that is extremely hard and expensive (99% is our private cost which is not small at this level) to keep those cheap board operational and usable. We lost about 30-50h for this project in total every day.

Until someone will make things together properly and provide a PR, it won't. But we don't receive help even for simple things https://forum.armbian.com/forum/54-help-wanted/ we ask while current maintainers are totally overloaded. Wishlist is estimated on millions / years of development.

I see, It looks like we don't have them for A20 But everything else ... so you will need to edit DT by hand. It could also work fine via armbian-config -> system

- (backup of) boot scripts are packed in u-boot or bsp package

- this is not a bug but feature. In some cases legacy kernels needs boot loader that is incompatible with current modern kernel.

OPUser · March 3, 2021

Is it more correct to build Armbian from the official branch v21.02 (if talking about the self build). Does a particular kernel and u-boot snapshots are linked to the official releases?

I tried to merge dtb of BananaPi and OrangePi, enabled some devices, but, unfortunately, I didn't get the desired result yet - not enough knowledge on this subject. Perhaps, v5.4 will be a good choice for now

Does a particular kernel and u-boot snapshots are linked to the official releases?

Yes, if you choose not to compile kernel from sources. But for full reproducible builds, we need to do this https://armbian.atlassian.net/browse/AR-175

hellf · March 28, 2021

I just wanted to chip in to confirm that on Orange Pi (A20) Armbian Bionic and Armbian Buster with mainline based kernel 5.10.y become erratic once fdtfile=sun7i-a20-orangepi.dtb is added.

Pinging shows ~ 50% packet loss over ~~any~~ the wired interface, uploading a log fails, the headless system is quite unusable, I assume similar in Desktop...
A kernel downgrade to 5.9.14-sunxi fixes things, maybe I'll find the time to slowly change to 5.10.y until it breaks, if this narrows done things.

/edit

my mistake, dues to metric the ping responses where send through the wired interface and got lost, once disabled the system is usable

Will try the fix for Banana Pro gmac dtb

for the record: happening since 5.10.4-sunxi apparently

Thank you for all the work and support you provide here Igor!

Created a new dtb with the change described in https://github.com/armbian/build/commit/95b0b601b72d5b28ee22496a42e657bc89ffb420 but to sun7i-a20-orangepi.dts and it seems to solve it, unfortunately adding this as a patch to git is a bit beyond my skills for now :/

another note: setting eth0 to 100Mbit did not solve it before

Its never to late to learn something

1. https://docs.armbian.com/Developer-Guide_Build-Preparation/

2. Run compilation with ./compile.sh CREATE_PATCHES="yes"

3. Skip u-boot change prompt and wait for kernel change prompt.

4. Open second terminal and edit file (under su):

sudo nano  cache/sources/linux-mainline/orange-pi-5.10/arch/arm/boot/dts/sun7i-a20-orangepi.dts

also do this for its other variant

sudo nano  cache/sources/linux-mainline/orange-pi-5.10/arch/arm/boot/dts/sun7i-a20-orangepi-mini.dts

and change those bits. Save and exit.

4. When you are done go back to initial terminal and proceed with compilation.
5. If everything went well, move patch from output/patch/ to patch/kernel/archive/sunxi-5.10/name_it_somehow.patch (you can also copy the same patch for sunx-5.11 since it will almost certainly work and its needed there too)

6. Create a PR

This might also help

sun7i-a20-orangepi.dts and it seems to solve it

Have you seen problems with HDMI and USB in 5.10.y kernel?

USB seems fine with 5.10.y as the WiFi comes back and also an external WiFi adapter is getting recognized and sees networks, what did you experience?

About HDMI, mine is running headless, but I will probably carry it towards a screen later and check

// well, anything HDMI related was missing from the orangepi dts so only uboot output worked, compared/copied from other A20 dts et voila, working hdmi output from 5.10.21-sunxi

// USB HID works, different WiFi dingle too, no issues here

I tried to merge with bananapi dts, but something still wrong. Could you please share you new sun7i-a20-orangepi.dts file?

see the patches https://github.com/armbian/build/pull/2750/commits/59797c3324e5f2db4a7727126a770049d274290c

Ok, thank you. My understanding was there are more changes required than just phy-mode = "rgmii"; -> phy-mode = "rgmii-id"; (for HDMI and USB)

?

the orangepi mini didn't have the hdmi lines missing

OPUser · April 1, 2021

So, was it a bad idea to decompile "sun7i-a20-orangepi.dtb" into "sun7i-a20-orangepi.dts", then edit and compile back to "sun7i-a20-orangepi.dtb"? Would it be more correct to edit/patch the kernel sources instead?

hellf · April 2, 2021

I took the original sources just for the device tree compilation, instructions from https://linux-sunxi.org/Mainline_Kernel_Howto

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git --depth=1
cd linux/
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- sunxi_defconfig

edit arch/arm/boot/dts/sun7i-a20-orangepi.dts

compile ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4 dtbs

copy arch/arm/boot/dts/sun7i-a20-orangepi.dtb to /boot/dtb/

the patch file has more than just phy-mode = "rgmii-id";, I guess you missed it?
