Earlier today I pushed a fairy large patchset containing various functional improvements of many boards.  If you have Allwinner board and some spare time:

 

1. Build DEV image/kernel with https://github.com/armbian/build (you need to add EXPERT="yes" to the config to unlock)

2. Install DEV kernel from beta repository

 

  1. Optional Defreeze kernel updates
  2. Switch to nightly kernel (armbian-config -> system -> Nightly)
  3. Reboot
  4. Switch to other kernel (armbian-config -> system -> Other -> DEV)

 

When board came up, do some exploration. Most important information is to find out if there is a regression toward kernel 4.14.y! Then make a test report https://github.com/armbian/testings#how-to-create-a-test-report. 
 

If you know how to fix certain problems, you are more than welcome! Our resources are tiny and we can't possible fix all problems :( 

 

This topic is a place to discuss how certain problems/bugs can be solved. 

 

When reporting a bug, provide logs with: armbianmonitor -u

 

Bugs:

- serial gadget console is not working (anywhere?)

- Pinebook doesn't boot properly

- Mesa (OS Mali drivers are enabled by default) / WebGL works on Debian based Chromium, fails on Ubuntu

 

I checked those:

 

 

With problems:
 

  • Pinebook 

 

Confirmed working:
 

  • Neo2 v1.1 512MB
  • Neo2 v1.1 1GB
  • Pine64
  • Orange Pi Zero Plus2 H5
  • Nanopi Duo http://ix.io/1uVC

  • Orangepi R1 http://ix.io/1uaP

  • Nanopi Neo Core 2 LTS
  • Nano Pi Neo Plus2
  • Tritium H3 and H5
  • Orange Pi Zero Plus
  • Bananapi M1

 

For now.

BTW.

Do you want to become a (Allwinner) board maintainer? Duties:
- responsible for content at the download page,

- running latests updates and managing bug list there.

can you go into a little more detail about managing bug list?

 

I have an embarrassing quantity of allwinner boards.

https://linux-sunxi.org/Linux_mainlining_effort#Status_Matrix
Essentials which should work, one board at the time, focus into the diff - what worked in 4.14.y and it doesn't work anymore. We should find very little. One example is DVFS not working on Orangepi Prime. Regulator bits were change a bit ... while they work at Orangepi PC2 which is the same in this manner. If you understand how to fix this, you fix it, otherwise you place a note here and ... I hope someone else will do this, else I will.

Tritium tested, fixed (DTS/config in u-boot back-ported from 2018.09), and complete with "testings" files merged.  I see NanoPi K1+ is done already, so my work here is done.  :-)


Great. Tritiums h3&h5 checked.

Can someone stress one of dumb regulator board too see if it doesn't result in a magic smoke ? :) Is there any heal for:

Hi @Igor Could you give me a hint/command for installing the DEV-Kernel?

I did compile DEV for the NanoPi Nero Core2, switched to nightly but I cant switch to DEV-Kernel (Other) because I dont know how to install this kernel.

 

PS: I did create a report without switching - maybe you could delete this one?

If you compiled on your own just transfer deb files (image and dtb at minimum) to your board and install with dpkg -i *.deb ... 

 

beta repository:

1. remove kernel and deb if it is not DEV already. apt purge linux-image* linux-dtb*

2. apt install linux-image-dev-sunxi64 linux-dtb-dev-sunxi64 (without 64 for 32 bit boards)

Hi. Is there overlays works on dev? I mean that as i know, overlays not works on dev and usb not available on OPi h5 with dev kernel. Or i missed something? )

Overlays are working on DEV since awhile, depending which SoC, I've recently added some overlays for H6 ...

What do you means by "usb not available on OPi h5" ? Which board did you try ? On some boards, you need to load usbhostX overlays ...

I mean that usb works only with overlays with mainline and next kernel, as i know. I was try dev kernel earler, and usb did not available.

I use OPi zero 2 plus with usb-lan dongle, and working usb for me is critical.

Do you have this "overlays=usbhost2 usbhost3" in /boot/armbianEnv.txt ?

If you don't want to use overlays, you can manually edit the Main DT and enable all "ehci" and "ohci" using "okay" statuses...

Please provide armbianmonitor -u since we need to know exactly what you are talking about.

Likewise and this topic here is to make sure it works before we push this out to all users. If it doesn't work at this moment, this is expected. In some cases.

Hi @rusatch, if you are using the 1.3GHz CPU overclock overlay in your "overlays=" line for your H5 then this could be the cause of your problem (overlay "cpu-clock-1.3GHz").  (If this isn't the case for you, then it's odd because USB works fine for me on four different boards I tried with the new 4.19 kernel...)

 

This overlay needed to be updated for 4.19.y, and if you load it by default in the current build then the load will fail and the DT will reset to the board default.  I just pushed an update for this for the new kernel (see https://github.com/armbian/build/commit/06451d37a64a4fd2599207722c73c9c160b63100).

 

The new 4.19.y mainline includes a much more complete cpu opp frequency table (nice!), with frequency and voltage definitions all the way to 1.368GHz.  For boards that have real DVFS-capable regulators then the higher frequencies will work by default.  So I updated the 1.3GHz overclock overlay hack for boards that only provide a fixed 1.3v maximum, and the new name for the overlay is "cpu-clock-1.3GHz-1.3v".

 

(Side note:  I removed the previous "cpu-clock-1.4GHz" overlay as given that the maximum clock speed default at 1.4v is now 1.368GHz it's not really worth maintaining one that goes to 1.396GHz.)

Hi @Igor, I've tried a top-of-tree H5 build so far on:

  • Neo2 v1.1 512MB
  • Neo2 v1.1 1GB
  • Orange Pi Zero Plus2 H5
  • Nano Pi Neo Plus2

...and all works well.  Very nice!!  :)  (These are all dumb regulator boards BTW)

 

Tests include USB (Wi-Fi and Ethernet dongles), H/W SPI interface (via spidev), multiple GPIOs (via libgpiod).  I've switched to 4.19.y for all of these now.

 

(I still have a few more boards that I'll dig up and try it on...)

@Igor - in 4.19.y it looks like the CPU temperature now reported by "/sys/class/thermal/thermal_zone0/temp" is ~10C greater than it was in previous kernels for the H5.  The "sun4i-gpadc-iio.c" driver in 4.19.y has numerous changes compared to the previous kernels, and I'm not sure if the previous value reported was incorrect and the new value is correct, or vice-versa.  This is consistent across all my different H5 boards.  Previously my H5 boards would idle around 30C (reported), now they idle at around 40C (reported): 

root@orangepizeroplus2:/sys/class/thermal/thermal_zone0# cat temp
40341
root@orangepizeroplus2:/sys/class/thermal/thermal_zone0#

Unfortunately I don't have a thermometer handy to check the case temperature of the CPU, but by finger test on the boards the CPU appears to physically be at the same temperature as with the previous kernel...  All boards are running idle with no activity (e.g., 240MHz/480MHz clock speed).

 

@Icenowy might you have any ideas regarding this?

Yes I did notice odd numbers but forgot to check. I do have some thermometer around but I am not close to the boards until tomorrow evening.

I found a bug with Orange Pi Prime: rebooting works fine but shutting down with poweroff command and cycling the power makes booting freeze at various stages.

 

More info:

there are four packages that did not updated with armbian-config when I was switching to nightly builds and later to dev branch: 

armbian-firmware/stretch,stretch 5.67.181116 all [upgradable from: 5.65]
armbian-tools-stretch/stretch 5.67.181116 arm64 [upgradable from: 5.65]
hostapd/stretch 3:2.6-99~armbian5.67.181116+1 arm64 [upgradable from: 3:2.6-99~armbian5.60+1]
sunxi-tools/stretch 1.4.2-2~armbian5.67.181116+1 arm64 [upgradable from: 1.4.2-2~armbian5.60+1]

I did fresh reinstalls two times: updating these packages after switching to nightly builds and after switching to dev branch. That made no difference, as soon as I power cycle the dev kernel it freezes at boot regardless of the versions of these packages.

 

Other than that the stability and functionality of the dev kernel seem to be great.

@5kft H5 is troublesome on thermal sensor, because the raw value - temperature function is not a single line, but two segments of line.

 

I don't know how is this dealed in sun4i-gpadc-iio.

 

Thanks @Icenowy!  I will try to dig further into this when I get time...!

Power off on H3/H5 is still not implemented AFAIK and don't know if this can be hacked somehow.

https://github.com/Icenowy/h3-arisc-shutdown

 

It works on boards which have external PMU, like A64.

I just wanted to make a clean shutdown before pulling the power plug.

The problem is that the Prime does not boot after I plug the power back in. As I said it freezes at various stages as seen in the boot log on the monitor connected via HDMI. I even saw a message "Unable to handle kernel paging request at address xxxxx" once.

Quick note - the Nano Pi Neo Core2 works as well with the new kernel.  Very nice that it clocks up to 1.37GHz by default now!

I found an old laser IR thermometer I have and when aiming measuring the heatsink on the Core2 it doesn't seem too far off (e.g. 32C measured vs 34 reported via "temp").  Perhaps the previous implementation was incorrect?  I'm curious what your results will be!

All by "boards garden" is now migrated to 4.19.y, nothing special to mentioned since all my boards are running headless, so I've never tested HDMI or Audio.

 

One small thing I've seen that bother me a little, and I didn't figured out how to fix, I don't recall how :

even if I have "verbosity=7" in /boot/armbianEnv.txt, kernel start booting with that verbosity, but suddenly becomes quiet until the login prompt.

Doesn any one remember which settings, probably in systemd, which cause that quietness ?

Quitness is due to changing default console to HDMI/serial console login. IMO its better that every day Joe see something on the hdmi screen. Both would be perfect ...

Where is that settings ? It wasn't like that in 4.18.12 ... Personally, I prefer keeping serial since all my boards are headless.

But in many of my post, I've encouraging Joe to get USB-TTL Serial dongle in their toolbox ... :P
