Build Ubuntu For i.MX8 Series Platform

[#1]

The Guide is how to use Ubuntu filesystem with i.MX8 series platform.At present, I had try it on i.MX8QXP with 4.14.98 kernel with ubuntu16.04.

The Document will be continuously updated with enable VPU, ubuntu18.04. The desktop we can chose Gnome or weston.  Because driver 

support issue, gc7000 series gpu not support render Gnome destop but it can render weston destop. 

Update 2019/7/31:

Ubuntu-i.MX8-weston.pdf  

Feature:

• weston + ubuntu18.04 + 4.14.98 kernel
• VPU (enable with gplay or gst-play) 
• GPU (could render desktop and run GPU demo under root privileges on Weston Desktop)

I also try ubuntu with gnome desktop, ubuntu18.04 can not run gnome, need use ubuntu19.04. But Gnome Desktop just render by CPU. 

-------------------------------------------------------------------------------------

Update 2020/3/6:

Ubuntu-i.MX8M.pdf

Just a simple guide for IMX8M series, will be  continuously updated.

Hi Gnar Fang,

Hi Gnar Fang,

            If i run weston --use-pixman then there is no issue with the display. This means HW acceleration is not working. This is due to the OpenGL ES driver issue or we need to enable HW acceleration during weston compilatio? Thanks

[gnar_fang]

Hi,

The issue is look like below.

1.warning: XDG_RUNTIME_DIR "/run/user/1001" is not configured correctly. Unix access mode must be 0700 (current mode is 700), and must be owned by the user (current owner is UID 1001).

2.[17:00:10.627] EGL error state: EGL_BAD_ALLOC (0x3003)
[17:00:10.627] EGL error state: EGL_SUCCESS (0x3000)
[17:00:10.627] failed to initialize egl

You can try it.

$ sudo su

$ XDG_RUNTIME_DIR =/run/user/1001

$ weston --tty=1

It is sure that need to enable HW acceleration during weston compilatio. which the config parameter in build weston? same as my guide?

[raajeshk88]

Hi Gnar Fang,

              My apologies for the late reply. Yes, i did use the arguments as per the documents to build Weston/Wayland. Regarding the rUNTIME_DIR whatever the ownership/permission i change the warning message continues to exist. Thanks

[gnar_fang]

Hi , I am not sure why cause it.  you can check if there are /usr/lib/aarch64-xx  libGLES, libEGL。if so, delete them.

Hi prashanth:
   How do you get this desktop? After I run "sudo -E weston --tty = 1", the displayed desktop is just the same as the yocto-wayland desktop. Does your system have apt-get install some software?

Tks~

[jiangyaqiang]

HI :

yes, It' yocto-wayland desktop. If you want other desktop , you can try apt-get to install .

Hi,Gnar Fang

Whether the GPU cannot be enabled as long as the Ubuntu file system is used?

[gnar_fang]

It guide is support use GPU when running Ubuntu file system

[gaobo]

In Ubuntu-i.MX8M.pdf ,I did not build weston in step 7 and I apt-get install lxqt.Use lxqt as the display desktop.I get follow results:

I have successfully loaded the gpu driver,But why no application uses gpu.When I do not use ubuntu filesyste,I get follow results:

have 26 apps uses gpu.

Please help me answer,thanks,have a nice day!

[gnar_fang]

Hi,  

our GPU is support wayland only.

You should try build the desktop with source code and enable xwayland.

[gaobo]

how to enable xwayland in lxqt.I can install gnome-wayland only.In lxqt desktopNo xwayland related configuration options.

[gnar_fang]

you can refernce the yocto script to build xwayland.  

But I am not sure if you use LXQT could use GPU, The best way,

you should build LXQT source code with our gpu driver instead of apt-get LXQT directly.

[chyun705]

Hi Gnar,

I want weston auto load on device startup, where can I add weston --tty=1?

[gnar_fang]

Refere to the yocto's  weston.ini file.

Hii PrashanthKumar 

Could you please provide me the steps for solving the below problem which you also encountered while running  sudo -E weston --tty=1

Hi all,

I am following the guide for imx8mq guide for ubuntu 20.04,

I came across an error for building weson-imx, the error is as follows.

libweston/compositor-drm.c: In function ‘hdr10_metadata_set_metadata’:
libweston/compositor-drm.c:7250:29: error: storage size of ‘hdr_metadata’ isn’t known
struct hdr_static_metadata hdr_metadata;

This query is already posted on this thread by @prashanthkumar, but there was no solution posted for it. So how can I solve this problem

[gavin67890]

I believe the Google Coral Dev Board 4GB and ASUS Tinker Edge T both use the NXP i.MX 8M processor.

Hence, would the Ubuntu i.MX 8M PDF at the top of this chain be applicable?

Has this instruction been updated at all?

And has anyone done it/be interested in helping out? If possible, I'd be thinking go to the latest LTS of Ubuntu.
