(victors) #2

supported features ?


(Igor) #3

All but: onboard wifi, power off, HDMI, RTC. Perhaps some other minor things …

Power off and RTC was already fixed but is not yet present in the image.


(Frank W.) #4

Hdmi (old patches), rtc and wifi are already ported to 4.19 see my kernel-repo

But nice that there is an archlinux-image is also now there. And with actual kernwl (imho currently too new).


(Igor) #5

Yes, I have been doing some research at your good work. I tried to bring up wifi with this patch https://pastebin.com/0zq4p513 but didn’t have luck. Not sure what is still missing. I guess slowly we will fix missing things …


(Frank W.) #6

Dts-patches are not enough…you need much more

See https://github.com/frank-w/BPI-R2-4.14/commits/4.19-wifi_new

3 commits begin with [wifi]


(Igor) #7

Hmm. Mainline u-boot + sources from this branch, your config https://pastebin.com/X8fp3zjP and boot parameters. No wifi: https://pastebin.com/ZnHiGhDL Any clue? Do I need anything extra in user space?

Can you point me to some proven image to see if wifi is not broken?


(Frank W.) #8

You can bootup my debian- or ubuntu-image and run wifi.sh (script which runs wmt-tools to create wifi-device and start hostapd)…but my images only contain 4.14.x

Have you added the driver-code?

Config and dts are not enough

according to this page: https://www.armbian.com/bananapi-r2/ 3rd party hardware USB WIFI AC (Realtek 8814AU) was tested or not (on BPI R2)?


(Igor) #10

Yes. It works perfectly fine. With Armbian.


(Igor) #11

Images were rebuilt - fixed power down, onboard wireless (but disabled due to poor performance) … and enabled and tested many 3rd party mPCI cards and USB adaptors.


(Igor) #12

Another rebuild - eMMC install is working now.


#13

Hey Igor,

Thanks for this. I had been patiently waiting/hoping for Armbian to release an image for this board :grinning: , despite being skeptical it would ever happen having read the historical discussions in your forum.

I know your team resources are limited, but I was wondering if you are now looking to target feature parity with Frank’s 4.14.x kernel/image ?

I had an idea of offering this board along with a pair of Nanopc T4s as a little dev/scrum team starter kit.

Regards

btw. i have uploaded today ~700MB in 5 Minutes (~2m away from r2) over internal wifi-card and over lan0 to my NAS =~ 2,3 MB/s (kernel 4.14.52 on debian stretch, 1 client simultanously connected 2.4GHz, 3 wifi overlapping on same channel [2])


(Maciek SzelÄ…gowski) #15

are there any option to upgrade eMMc install? (from your latest rebuild)


(Igor) #16

That is nice. I had different kind of troubles - I can connect to my router but not long after driver is crashed. I might look into this once again when I find some time.

No. Those kernels are too different which means a lot of work. Except HDMI, there is nothing that important left to port.

No, only supported builds have that luxury. This require costly manual intervention and is directly connected with our small resources.


(Frank W.) #17

which Parts are too different? it’s mainline-Kernel, i’ve added features by merges, which you can also use to integrate in your Kernel…
