[Banana Pi BPI-M5 with Amlogic S905X3 chip design]

I tried to troubleshoot some USB throughput issues with the M2 Pro unit and possibly narrowed it down to all USB ports apparently being on the same USB 2.0 Bus:

lsusb -t
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/2p, 480M
    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
        |__ Port 2: Dev 4, If 0, Class=Wireless, Driver=btusb, 480M
        |__ Port 2: Dev 4, If 1, Class=Wireless, Driver=btusb, 480M
        |__ Port 2: Dev 4, If 2, Class=Vendor Specific Class, Driver=rtl8821cu, 480M

 

From lsusb -v USB HUBs look like this:

Bus 002 Device 002: ID 2109:0817 VIA Labs, Inc. USB3.0 Hub             

Bus 001 Device 002: ID 2109:2817 VIA Labs, Inc. USB2.0 Hub             

 

While plugging things into various ports on the board this is what they layout looks like:

1-1.1 - bottom USB
1-1.2 - WiFi
1-1.4 - top USB
1-2 - OTG

 

Everything is tied to Bus 01.

 

There does not appear to be anything on the Bus 02 , which is what apparently actually is the USB 3.0 (5000M).

 

I am a tiny bit out of my depth here, am I reading the output right? Is the M2 board design really broken?

[x96 Air specifics only]

Hi, did anyone manage to install Armbian on the internal eMMC of X96 Air?

[x96 Air specifics only]

Hi, a stupid question, how can I make the X96 Air actually boot from SD-Card? I wrote Armbian_20.05.3_Arm-64_buster_current_5.7.0-rc2_20200425.img to sd-card, updated u-boot settings, plugged the sd-card in to Air, powered on and it boots into Android again. Feels like I am missing some step in there

[HDMI multimedia on H6]

Had a bit of a success with HDMI audio and also video acceleration on OrangePi 3. What was needed was to apply some patches from LibreELEC, namely ones from projects/Allwinner/patches/linux/ .

For HDMI audio to work you need 0004-sun4i-i2s-improvements.patch , which contains support for I2S on H6. When done right you should see in dmesg:

asoc-simple-card sound: i2s-hifi <-> 5091000.i2s mapping ok

Also what helped was an IRC chat that Jernej had with mirko some time ago:

https://irclog.whitequark.org/linux-sunxi/2018-03-14

 

For video acceleration you need 0005-cedrus-improvements.patch and compile Cedrus driver. When done right you should see in dmesg:

cedrus 1c0e000.video-codec: Device registered as /dev/video0

 

For a good measure I applied other patches in that directory as well, some needed modifications to apply to 5.5 kernel (LibreELEC uses 5.4) .

Then FFMPEG needs to be compiled with v4l2_request to actually do the acceleration

 

To get Kodi GUI acceleration working you need to compile mesa 20.0.0-devel from Mesa GIT. Kodi then needs to be compiled as GBM version. I also applied patches that LibreELEC has for Kodi into my Kodi tree.

 

@jernej sounds the above about right?

[Orangepi 3 h6 allwiner chip]

Anyone caught this one?

https://www.phoronix.com/scan.php?page=news_item&px=Mali-T720-Stable-Mesa-20.0

 

It is present in mesa git master, going to try to compile it.

[How to build my own image or kernel?]

Probably doing something stupid here. The whole kernel build process is triggered every single time when recompiling the image. I would expect only to rebuild files I have modified, or drivers I have added during menuconfig.

 

I did set this in userpatches/config-example.conf:

CLEAN_LEVEL="debs"

 

But still getting:

[ o.k. ] Checking git sources [ u-boot v2019.10 ]
[ .... ]  Cleaning ....  [ 8 files ]

[ o.k. ] Checking git sources [ linux-mainline orange-pi-5.3 ]
[ .... ]  Cleaning ....  [ 206 files ]

 

And then it compiles the whole thing all over again.

 

Can someone please point me to what I am doing wrong here?
