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.

Hello Gnar,

Thank you for posting this detailed document. I was trying to follow it for nxp imx8m-mini evk. I have been able to build yocto for this board and that seems to work fine but now want to try ubuntu with weston on this evk. I have these questions for you in your Ubuntu-i.MX8-weston.pdf document.

In section 9 you write:

2)copy libdrm,wayland vpu-firmware from yocto
$sudo cp -Pra libdrm/2.4.91.imx-r0/image/* ubuntu18.04/
$sudo cp -Pra imx-gpu-viv/1_6.2.4.p4.0-aarch64-r0/image/* ubuntu18.04/
$sudo cp -Pra imx-dpu-g2d-1.7.0/imx-dpu-g2d/1.7.0-r0/image/* ubuntu18.04/
$sudo cp -r all-poky-linux/firmware-imx/1_8.1-r0/image/* ubuntu18.04/

Could you tell me from which folder (cd ~/????)  you are running these commands? Also this folder ubuntu 18.04 does not exist anywhere, where does it get used later? I do not see any other reference to "ubuntu 18.04" folder in this document.

Is imx-dpu-g2d a typo, should it be imx-gpu-g2d ?

Also you say:

2.Compile the kernel separately to replace yocto kernel

Do you mean bitbake linux-imx after I have built yocto? Currently in the yocto build I do see that a kernel Image that has been built.

Thanks,

Amrit

[gnar_fang]

Hi, Amrit

1.which folder (cd ~/????) 

The command run Host PC side. To  build a ubuntu rootfs, decompression rootfs first such as tar -xvf ubuntu-base-18.04.2-base-arm64.tar.gz -C ubuntu-rootfs, in my case  modify ubuntu-rootfs to ubuntu 18.04, May cause you misunderstand and I will uniform naming. This command purpose

is copy  libraries related GPU to ubuntu-rootfs.

2.Compile the kernel separately

Because the GPU dirver be builded as galcore.ko by yocto default. So compile the kernel separately to make Image include gpu dirver. In kernel source code(I download form linux-imx - i.MX Linux kernel , not use the yocto code), after command $ make menuconfig, you can see the .config

CONFIG_MXC_GPU_VIV=y.

Hi Gnar,

i was curious whether you have tested a webcam with ubuntu and seen if it works?  i'm struggling to get a simple logitech webcam to work.  It looks like i'm getting a dmesg alert that "VPU_firmware_download Failed"... so i assume the VPU firmware is messed up.

maybe i copied in the wrong file at some point...

k

[gnar_fang]

Hi, Kyle

     I am not test webcam but other one test it ok. I am not sure he do other config for it. If you webcam is usb camera, may should enable UVC driver in kernel. About VPU firmware, are you copy it under  /lib/firmware ? You also can copy unit_test file form yocto,  use v4l2 to open camera.

[Kyle_Fox]

Hi Gnar,

I think i've gotten a bit confused on what specifically to copy.  From your awesome manual (Ubuntu-imx8-weston.pdf)
there are several commands here:

2) copy libdrm, wayland, vpu-firmware from yocto

$sudo cp -Pra libdrm/2.4.91.imx-r0/image/* ubuntu18.04/

$sudo cp -Pra imx-gpu-viv/1_6.2.4.p4.0-aarch64-r0/image/* ubuntu18.04/

$sudo cp -Pra imx-dpu-g2d-1.7.0/imx-dpu-g2d/1.7.0-ro/image/* ubuntu 18.04/

$sudo cp -r all-poky-linux/firmware-imx/1_8.1-r0/image/* ubuntu18.04/

What would help me is to understand the actual folder paths for each of them.

My assumption is that you are copying from the Yocto build... could you give me the full paths to /libdrm/2.4.91.imx-ro/image/,  /imx-gpu-viv/1_6.2.4.p4.0-aarch64-ro/image/, /imx-dpu-g2d-1.7.0/imx-dpu-g2d/1.7.0-ro/image/* and all-poky-linux/firmware-imx/1_8.1-r0/image/*

2nd, when you point out the destination folder of 'ubuntu18.04/'  do i assume that /ubuntu18.04/ is the base of the ubuntu rootfs?

thanks

Hello Gnar and Kyle,

I am glad to see that more than one person is working on this project. First of all thank you Gnar for creating the documents and outlining the essential steps.

Kyle,

I also went through and located all folder that need to be copied from yocto build folders to ~/rootfs/ubuntu-rootfs (or ~/rootfs/ubuntu18.04). Here are the  the source folder names in each case:

cd ~/imx-yocto-bsp/build/tmp/work/aarch64-mx8mm-poky-linux

sudo cp -Pra libdrm/2.4.91.imx-r0/image/* ~/rootfs/ubuntu-rootfs

sudo cp -Pra imx-gpu-viv/1_6.2.4.p4.0-aarch64-r0/image/* ~/rootfs/ubuntu-rootfs

sudo cp -Pra ~/imx-yocto-bsp/build/tmp/work/aarch64-mx8mm-poky-linux/imx-gpu-g2d/6.2.4.p4.0-r0/image/* ~/rootfs/ubuntu-rootfs

cd ~/imx-yocto-bsp/build/tmp/work

sudo cp -r all-poky-linux/firmware-imx/1_8.1-r0/image/* ~/rootfs/ubuntu-rootfs

In my case rootfs folder is ~/rootfs/ubuntu-rootfs.

Gnar,

I am able to run ubuntu18.04 in basic form with Gnome or xfce4 but still in the process of trying to put all the components in my rootfs. I noticed a weird error in step 3) for weston-imx.

Here is the error log,  when I run autogen for weston-imx:

Hi Amrit

    1. I am install gnome base ubuntu18.04 meet error on 8QXP but sucessful with ubuntu19.04. At present, gnome not support GPU and use the CPU to render the desktop,

the performance is not very optimistic. so i am try debug GNOME to support GPU but it need some time.

    2. When you build weston-imx meet error.  If you had install gnome or xfce4(BTW: it base on X11, 8 series GPU is only support wayland, but if use CPU to render desktop,

xfce4 is better than gnome because gnome is more complex), please build weston-imx without it because some component of GNOME of xfce4 effect weston-imx build.

if not,try use the command:

#./autogen.sh --prefix=/usr --disable-silent-rules --disable-dependency-tracking  --enable-setuid-install --disable-rdp-compositor --enable-clients --enable-simple-clients --enable-demo-clients-install --disable-colord --enable-egl --enable-simple-egl-clients --enable-fbdev-compositor --disable-headless-compositor --enable-drm-compositor --enable-weston-launch --disable-lcms --disable-libunwind --with-pam --disable-vaapi-recorder --enable-wayland-compositor --without-webp --disable-x11-compositor --enable-xwayland --enable-imxg2d --enable-imxgpu --enable-drm-compositor --enable-opengl

   3. I had not meet the err, you can reference :cross compiling - What's the difference of "./configure" option "--build", "--host" and "--target"? ...  .

Hello Gnar,

Thank you for your reply. I think I am now very close to building ubuntu after following your document.

I now have these remaining items.

1. I do not see anything called  imx-dpu-2d in my yocto build folder. So I am not able to run this step in your document:

sudo cp -Pra imx-dpu-g2d-1.7.0/imx-dpu-g2d/1.7.0-r0/image/* ubuntu18.04/

My DISTRO is fsl-imx-xwayland and MACHINE is imx8mmevk

2.. I tried the new autogen step as you mentioned in your last post for weston-imx but it still does not build. I now get different errors during autogen step. Here is my log:

.........................

Consider adjusting the PKG_CONFIG_PATH environment variable if you

installed software in a non-standard prefix.

Alternatively, you may set the environment variables XWAYLAND_CFLAGS

and XWAYLAND_LIBS to avoid the need to call pkg-config.

See the pkg-config man page for more details.

Any suggestions?

Thank you so much.

Amrit

[gnar_fang]

Hi,Anrit

1.  imx-dpu-2d path in yocto is /buildxwayland/tmp/work/aarch64-mx8mm-poky-linux/imx-gpu-g2d  ,8MM have not DPU.

2.  back to first command:

./autogen.sh --prefix=/usr --disable-silent-rules --disable-dependency-tracking --enable-setuid-install --disable-rdp-compositor --enable-clients --enable-simple- clients --enable-demo-clients-install --disable-colord --enable-egl --enable- simple-egl-clients --enable-fbdev-compositor --disable-headless-compositor -- enable-drm-compositor --enable-weston-launch --disable-lcms --disable-libunwind --with-pam --disable-vaapi-recorder --enable-wayland-compositor --without-webp --disable-x11-compositor --disable-xwayland

The error log is :

1)configure: WARNING: you should use --build, --host, --target

2)checking build system type... Invalid configuration `clients': machine `clients' not recognized

Are you build in qemu enviroment ? I had not meet the error in my step and not set any  enviroment variables. Try google how build weston, according to the log you need 

add the arguments about  --build, --host, --target.

The second command, try disable xwayland at first. 

The xwayland is not necessary.

First of all, thank you very much for your proposal。But i have a question that I hope you can help me with this。In Ubuntu-imx8.pdf setp 2 Compile the kernel separately to replace yocto kernel，Specifically which is kernel to replace yocto kernel?

thanks!

[gnar_fang]

Hi, gao

Because in default, GPU driver  galcore is compiled as .ko file, so need compile the kernel separately to make galcore in kernel.

BR

Gnar

[gaobo]

thanks for your answer.Can you tell me how to compile the kernel separetely? I use fellowing methods make it ：

bitbake -c compile -f -v linux-imx 
bitbake linux-imx -c compile_kernelmodules -f -v
bitbake -c deploy -f -v linux-imx  

result：

Compare with before：

galcore used numbers different.and no have qca6174 driver.and a lot of drivers have been added。

how to resolve it？

[gnar_fang]

Hi, 

A easy way is download linux-imx for linux-imx - i.MX Linux kernel , Then use command "$ make defconfig,  $ make" to build Image .

Use the Image replace your current Image.

[toussi]

Hi nxf47724‌ : The GPU can't render gnome because of limitations in the OpenGL library or is there another reason?

[gnar_fang]

Yes, may GPU dirver not fit.

[prashanthkumar]

Hi,

I am also porting Ubuntu 18.04 to iMX8 Quad Max custom board with 4.14.98 BSP by referring https://community.nxp.com/servlet/JiveServlet/download/343939-3-454211/Ubuntu-i.MX8-weston.pdf  Document.

Till section 9. copy imx-gpu-viv in mentioned document able to understand properly. But after section 10.build weston, its not saying that where need to build weston, wayland, gstreamer and gst-plugins? How to link/add above features with "ubuntu-rootfs" ?

Best Regards,

How to copy "weston" libraries from yocto build to ubuntu-rootfs?
Thank you.

Hi,

This is a script to start up arm64-linux simulate environment.

You build weston in the enviroment？

I had not meet the issue. Check if there are /usr/lib/aarch64-xx  libGLES, libEGL。if so, delete them.

BR,

Gnar

[gnar_fang]

Hi,

According my setp, start simulate ARM64 enviroment on host and build weston.

Then copy whole filesystem, not only copy weston lib.

[prashanthkumar]

Hi Gnar,

I used section "10.build weston" steps to build Weston in ubuntu-rootfs in qemu enviroment.

Also copying full ubuntu-rootfs to board using below steps mentioned in provided user guide.

12. replace filesystem
$ mkdir mountpoint
$ umount /dev/sdb2
$ mkfs.ext4 /dev/sdb2
$ mount /dev/sdb2 /home/gnar/mountpoint
$ cp -a /home/gnar/rootfs/ubuntu-rootfs /* /home/gnar/mountpoint/
umount /home/gnar/mountpoint
sync

But  still facing same issue.

Can you please suggest how to resolve  "drm-backend.so"  loading issue?

Also kindly provide path to copy "weston" related libraries from yocto build to ubuntu-rootfs.

Regards,

Prashanth Kumar K

[lorenzo_giraudi]

Thank you Gnar, deleting those libraries worked for me.

Several programs downloaded from "apt-get" (like firefox, chromium and others) try to use X11. We see that you disable xwayland during the weston compilation.
What are the reasons for this? Do you think that having xwayland may solve the issue? Do you have any idea of how to get xwayland?

Thank you a lot for your help.

Best regards,

Lorenzo

Hi Gnar,

Can you please provide your built ubuntu-rootfs.tar.gz file system for testing in iMX8QM custom board.

Thanks in advance.

Hi Gnar,

Is there any update regarding above issue for Ubuntu 18.04 using Weston file system nxf47724‌ ?

Thanks in advance.

[linux_downey]

Hi Gnar Fang：

   I'm trying to port the ubuntu 18.04  to my i.mx8mq-evk,I read your document and followed,But I get two errors:

    1. Step 9,part 2: I can't find the targets  "libdrm/2.4.91.imx-r0/image/*"  and  "imx-dpu-g2d-1.7.0/imx-dpu-g2d/1.7.0-r0/image/*" ,I'm sure that these two             target don't exist in my yocto project. I assume that the i.mx8mq-evk does not have dpu,but for libdrm,I'm not sure,So please give me a signal.

               btw, I compile with instructions:

                        DISTRO=fsl-imx-wayland MACHINE=imx8mqevk source fsl-setup-release.sh -b build

                         bitbake fsl-image-qt5-validation-imx

   2.Regardless the error 1 above,I'm trying to continue with the document,but when I compile  weston-imx,some errors occured:

         steps below:

               git clone https://source.codeaurora.org/external/imx/weston-imx.git

               cd weston-imx

               git checkout fb563901657b296c7c7c86d26602a622429e334f

               ./autogen.sh --prefix=/usr --disable-silent-rules --disable-dependency-tracking .........

               make

  This is error message:

Hi, 

I also found 8mq yocto have not libdrm. I will check it next week.

I think the drm is a necessary component for Linux display.

Hi Gnar Fang:

   Thanks for your reply，Looking forward to your updates.

   BTW,Please check the second question above(compile weston-imx errors )

[gnar_fang]

Hi,

1. libdrm is under buildxwayland/tmp/work/aarch64-poky-linux.

2. The issue may be caused by your rootfs lost libdrm, copy libdrm to your rootfs.

If you have any other question could tell me. These day have too many other case, may reply late.

[prashanthkumar]

Hi Gnar,

We are able to get GUI with Weston, but this GUI look is not like desktop Ubuntu GUI.
Whether you are getting same GUI?
The terminal showing following output,

# lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.2 LTS
Release:        18.04
Codename:    bionic

Regards,

Prashanth Kumar K

[gnar_fang]

Hi,prashanth

You install weston, so it show weston GUI. I think you want to get Gnome GUI, but I enable it just with CPU sotfware render (just apt-get                install gnome-core).   Gnome GUI with GPU render meet some mistakes.

[prashanthkumar]

Hi Gnar,

   Thanks for your reply. Is there any updated Documents for building Ubuntu 18.04 on i.MX8 platform.

Best Regards,

Prashanth Kumar K

[gnar_fang]

Hi，Prashanth

I have not received new requirement, so there is not any update.

BR

Gnar

[linux_downey]

Hi Gnar Fang:

      I've found the libdrm/ under aarch64-poky-linux/, and copied it to corresponding directory which you guide in the document.

But , I got another error when I compiled weston-imx :

```

         ...

         In file included from libweston/g2d-renderer.c:44:0:
         libweston/g2d-renderer.h:30:10: fatal error: g2dExt.h: No such file or directory
         #include <g2dExt.h>
         ^~~~~~~~~~
         compilation terminated.

         Makefile:5107: recipe for target 'libweston/g2d_renderer_la-g2d-renderer.lo' failed

```

There seems to be some system libraries(libweston) that are missing, or some packages that I haven't installed but that library depends on that package.  

I tried again to build from scratch to avoid an operational error problem, but the problem was the same on both occasions.

Regards.

Downey.

HI  Gnar Fang:

Following your doc, I can success to run the ubuntu18.04 on imx8mq, but I face a problem: the system could not load firmware:

imx-sdma 30bd0000.sdma: external firmware not found, using ROM firmware

I have comfirm the firwmware is in /lib/firmware/ .

Do you have the same problem ? or where should I check ?

Thanks.

[linux_downey]

Hi jiang yaqiang:

   could you please tell me where do you find the imx-dpu-g2d-1.7.0 directory，I can't find this lib ,So I get an error when I compile weston-imx.

   I put this issue above , But no one replied about this.

Thanks a lot.

downey

[linux_downey]

Hi Gnar,
   could you please check this issue about the header file <g2dExt.h>,It seems about dpu,But I can't find the dpu lib under my yocto project.

Thanks a lot.

Best Regards.

downey.

[jiangyaqiang]

Hi downey:

I don't know which platform you are using.

I use imx8md/q , it doesn't support "g2d", so just add "--disable-imxg2d" when config weston-imx with fix the issue.

Hi Gnar Fang,

      While running the Weston tty im getting error either "No such device or directory" or "Fatal : DRM should run in background". Could you please share some guidance in this. Thanks

Regards,

Raajesh K

[gnar_fang]

Which platform are you used?

[raajeshk88]

Hi Gnar Fang,

       Currently I am using IM8MM DDR4 EVK.Thanks

[raajeshk88]

Hi Prashanth,

               I am getting a similar error could you please share how you got the "drm need to run on background" error. Thanks

[gnar_fang]

Hi， I will write the guide for 8MM about this week. 

[raajeshk88]

Hi Gnar Fang,

            Thanks looking forward to it, kindly let me know once done. I will also update if i make any progress.

[gnar_fang]

Hi, I had update the DOC for enable weston.  See if there is  gpu driver .

你好，

请问您的问题解决了吗？

我也遇到了相同的问题，我解决的方法是在内核配置的时候只让它编译出模块并不加载。系统起来之后再手动加载。但是这样会有一些依赖问题的错误log打印。虽然能解决，但是我觉得方法不是很好。

您有更好的办法吗？

[jiangyaqiang]

HI gaobo:

已经解决。关键是下面两个文件，你可以参考一下。

/lib/udev/rules.d/50-firmware.rules

/usr/bin/firmware.sh

cat /lib/udev/rules.d/50-firmware.rules

1. stub for immediately telling the kernel that userspace firmware loading

2. failed; necessary to avoid long timeouts with CONFIG_FW_LOADER_USER_HELPER=y

#SUBSYSTEM=="firmware", ACTION=="add", ATTR="-1"

SUBSYSTEM=="firmware", ACTION=="add", RUN+="/bin/sh /usr/bin/firmware.sh"

imx8m@localhost:~$ cat /usr/bin/firmware.sh

#echo 1 > /sys/$DEVPATH/loading

#cat $HOTPLUG_FW_DIR > > /sysfs/$DEVPATH/data

#echo 0 > /sys/$DEVPATH/loading

echo -n 1 > /sys/$DEVPATH/loading

sleep 1

cat /lib/firmware/$FIRMWARE > /sys/$DEVPATH/data

if ; then

1. echo -n 1 > /sys/$DEVPATH/loading

echo -n 0 > /sys/$DEVPATH/loading

fi

Hi jiangyaqiang:

非常感谢您的回复。我按照您的步骤进行操作了，

iqi@imx8mqevk:~$ cat /lib/udev/rules.d/50-firmware.rules
# stub for immediately telling the kernel that userspace firmware loading
# failed; necessary to avoid long timeouts with CONFIG_FW_LOADER_USER_HELPER=y

cat /lib/firmware/$FIRMWARE > /sys/$DEVPATH/data

if ; then
echo -n 1 > /sys/$DEVPATH/loading

echo -n 0 > /sys/$DEVPATH/loading

还是会出现那个问题

请问您是怎么调试的呢？（我不确定是否是我的firmware.sh文件是否配置的有问题，脚本文件中的环境变量是否还需要单独配置）

请帮忙指点一下，感谢！！！
