Opi+2e / mainline / ethernet not working any more

vincele · November 26, 2016

Hello,

Just returning after a little while,

I cannot get ethernet working on my opi+2e with mainline kernel, direct cable

connection to PC, no serial console at hand, neither HDMI output, so I had

the habit of blindly booting then sshing into the box...

I tried my personal config + megous repo, xenial or jessie, current armbian repo

nothing coming out of eth on the PC (tcpdump -i eth0). LEDs, green solid on, red

heartbeating, orange eth led blinking slowly.

I then reverted back to montjoie's repo (default for dev BRANCH), for identical results.

Could this be the updated u-boot (I think I saw a new version being used) ?

Or is this expected to be working, and thus something on my side ?

Now trying to build a legacy-kernel based image, to double-check...

You should succeed by choosing 'Banana Pi M2+' instead. It's just device tree stuff that's missing. When choosing BPi M2+ you 'loose' functionality of 3rd USB host port and one led. But using dtc tool you can simply add this later.

Alternative would be to patch the DT bits already in prior to building kernel/image but at least me got too annoyed since DT bits always have to match kernel version so I chose the 'patch it in later' approach all the time.

(I did all my GBit Ethernet tests for montjoe on OPi Plus 2E so it's known to work)

tkaiser · November 26, 2016

Hmm... I just built an OS image with dev kernel, switched to megi's 4.9 branch before and used BPi M2+ settings: No network. Then I remembered what I did last time:

sed -i '1isetenv fdtfile sun8i-h3-orangepi-plus.dtb' /boot/boot.cmd
mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
reboot

Wrong DT anyway (since no USB hub on Plus 2E and now one or two USB ports not useable) but Ethernet works fine. Just did a quick test again my MacBook:

With legacy kernel we got only 630/930 Mbits/sec here. BTW: regarding Ethernet: https://irclog.whitequark.org/linux-sunxi/2016-11-26#18270413;

vincele · November 27, 2016

OK, mounted the sdcard on the PC, did the above and it worked.

Now on to try it with the other branch & config...

What woud be needed to make it work properly as "./compile [...] BOARD=orangepiplus2e" ?

Copy sun8i-h3-orangepi-plus.dtb as sun8i-h3-orangepi-plus2e.dtb somewhere in userpatches ?

Anything else ?

Thanks

tkaiser · November 27, 2016

Using DT for Plus with 2E is wrong anyway. Better way to deal with would be to figure out missing DT bits for the other GbE boards based on .dts for the Plus, add this as DT patches to patches/kernel and send a PR

vincele · November 30, 2016

Sorry, but I'm still lost...

which dts should I base my comparison on ?

- /boot/dtb/sun8i-h3-orangepi-plus{,2e}.dtb converted to dts ?

- megous branch kernel source code

- u-boot source code

I think I should diff /boot/dtb/sun8i-h3-orangepi-plus{,2e}.dts

Then apply this diff to sun8i-h3-orangepi-plus2e.dts in kernel or u-boot source code,

but replacing the adresses by handle to the right stuff.

Is that right ?

zador.blood.stained · November 30, 2016

@vincele

You should compare .dts files in megous branch, more specifically patches like this one https://github.com/megous/linux/commit/58d6b89acffdfc3025ff10d56851ae6f847e9a70 should be applied to all H3 boards .dts files

nxtv2.0 · December 2, 2016

Can you please post where can i find a dtb for the Plus 2E with gigabit ethernet working and USB fully working(+ USB OTG)

and if there isn't how do i modify existing dtb files for Plus 2E to support gigabit ethernet.

martinayotte · December 9, 2016

Fixed done and committed as explain in https://forum.armbian.com/index.php/topic/3029-mainline-ethernet-driver-h3/

vincele · December 9, 2016

Thanks a lot Martin, I think your DTS patch fixed it for my opi+2e.

I had been trying to understand why it broke, and why the old method from above was not working any more for the last few days.

I started to diff DTSes around but not really knowing what I was doing, and because of my total lack of output (no serial console, nor any HDMI) it was really painful to blindly test random changes...

I'll get serial tomorrow (or at least I hope so), so it will be easier to help

martinayotte · December 9, 2016

@TKaiser gave me hint in the other thread.

The problem is that older u-Boot had the FDT file set wrongly to "orangepi-plus" not "orangepi-plus-2e", which make the loading DTB for Plus not for Plus2E.

So, diffing the DTS for Plus2E against PC+ was not revealing any thing, but diffing Plus against Plus2E reveal a big thing :

EMAC wasn't declared the same way ! There was also some GMAC-3V3 missing !

Looking at the schematics for PC+, there wasn't any PD6/EMAC-PWR-EN been used, but in both Plus and Plus2E there is a power switch.

In other words, Plus2E DTS never been completed since EMAC never got power, except if using wrong Plus DTS by pure concidence ...

vincele · December 11, 2016

I now have serial, even if it's epic getting my tiny crappy connectors hooked to the opi pins...

So I was able to capture a crash happening at halt time (probably reboot too, not tested yet).

Does someone suffer similar problem ?
