Hi all,

I need to run X server on Sabre board, using default LVDS display.

I tried to install xserver and mesa driver, but when I try to start xsever I have following messages:

Does anybody tried to run xserver?

By the way, I’m using kernel 4.10

Hi Jeanluc,

I’ve only re-built the mesa driver with etnaviv support for Debian Jessie (and Stretch) Ubuntu 16.04 was just too old…

Hi Robert,

I followed your guide for Wandboard 2D/3D, using kernel version 4.12.0-rc1-armv7-x0 and debian-8.8-minimal-armhf-2017-05-11.

I also installed xserver-xorg-input-evdev and x11-server-utils.

I connected the Sabre board to an HDMI monitor; i’m able to see the freescale logo when boot starts, and the console when starts rootfs.

but if try to run Xorg, the screen became blanc and it seems like the system is crashed, because I’m not able to come back to arm@debian on the debug uart.

The file Xorg.0.log does not report errors. The content is:

Hi Jean,

There’s something wrong with my MCIMX6Q, hdmi doesn’t work. So to verify everything is still good, I installed xfce4 and the mesa/etnaviv video stack. In this case, with a Dual Core Wandboard with v4.12.0-rc1 and debian 8.x:

No lockup’s and 2D/3D acceleration is working.

dmesg:
dmesg.txt (22.1 KB)
Xorg Log:
xorglog.txt (17.8 KB)
glxinfo.log:
glxinfo.txt (8.4 KB)

xorg.conf:

Section "Monitor"
      Identifier      "Builtin Default Monitor"
EndSection
Section "Device"
      Identifier      "Builtin Default fbdev Device 0"
      Driver          "armada"
EndSection
Section "Screen"
      Identifier      "Builtin Default fbdev Screen 0"
      Device          "Builtin Default fbdev Device 0"
      Monitor         "Builtin Default Monitor"
      DefaultDepth    24
EndSection
Section "ServerLayout"
      Identifier      "Builtin Default Layout"
      Screen          "Builtin Default fbdev Screen 0"
EndSection

Hi Robert,
thank you for your test and your quick reply.

I’d like to be in your same conditions; so, which file did you use for debian rootfs?

For mesa/etnaviv video stack do you mean the packet xserver-xorg-video-armada-etnaviv?

Regards,
Jeanluc

Hi Jeanluc,

I used this one:
https://eewiki.net/display/linuxonarm/i.MX6q+SABRE+Board+for+Smart+Devices#i.MX6qSABREBoardforSmartDevices-Debian8

While debugging, i updated that page with u-boot and the kernel bump’s.

So xserver-xorg-video-armada-etnaviv is just the 2D driver for xorg, but it knows what 3D driver in mesa to call when a 3D application is started.

Regards,

Hi Robert,

now I’m able to run xfce4, glxinfo, glxgears.

Then I compiled the glmark2 benchmark, as described in https://fixmynix.com/how-to-install-glmark2-from-source-in-debian/

I compiled this benchmark successfully, but if I run it I have following error:
Glmark2 need OpenGL(ES) version >= 2.0 to run (but version string is: ‘1.4 Mesa 17.1.0’)!

If I runglxinfo I see OpenGL version string 1.4 Mesa 17.1.0, but also
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 17.1.0

Can you please explain me the difference between version string and profile version string?

Is it possible to run the glmark2 test successfully?

Regards,

8

Hi Jeanluc,

It looks like you built glmark2 with the wrong flag, in that how-to-install link:

./waf configure --with-flavors=x11-gl

Instead use:

./waf configure --with-flavors=x11-glesv2

For OpenGL ES 2.0

Regards,

9

Hi Robert,

after install this two missing packages:

  • libegl1-mesa-dev
  • libgles2-mesa-dev

I’m able to compile the glmark2 benchmark as you suggested and it works really great.

Thank you for your support.

Regards,

Hi Robert,

I have a wifi module with pci-express interface. The chipset of such module is the Atheros AR5B97, and it is supported by the ath9k linux driver. I found the ath9k folder in the latest kernel I compiled (4.12).

So I’d like to try to use it on the Sabre board; can you explain me how to add in kernel the support for the iMX6 PCIe interface and how add the wifi module driver?

Regards,

11

Hi Jeanluc,

After you run ./build_kernel.sh, menuconfig will pop up…

Bus support —>
[] PCI support
[] Message Signaled Interrupts (MSI and MSI-X)
DesignWare PCI Core Support —>
[*] Freescale i.MX6 PCIe controller

Then also add the pcie device you need.

Regards,

14

Hi Robert,

I tried to modify the kernel as you suggested, but kernel locks just at the beginning, without sending any message to the debug serial.

If I remove the wifi module from the board, then kernel starts.

By the way, the wifi module driver was already included in kernel; it’s the ath9k.

It works with an old kernel/file system provided by Freescale (Ltib).

Do you have any suggestions?

Regards,

Hi Jeanluc,

It’s lockup up for me too. But u-boot see’s it:

Bingo, got it!

now to start a git bisect from 4.9.x to mainline…

Regards,

and 4.10.17-armv7-x2 also works, so the regression looks to have occurred in 4.11-rcX

Hi Robert,

thank you for you investigation.

This evening I’ll try kernel 4.10.17-armv7-x2 and I’ll let you know.

Hi Robert,

now kernel start and pice-wifi module is recognized:

Hi Jeanluc,

With Fabio help at NXP’s help we got this working:

debian@arm:~$ lspci

01:00.0 Network controller: Intel Corporation Wireless 3160 (rev cb)
debian@arm:~$ uname -r
4.12.0-rc5-armv7-x0

This u-boot patch is needed:

http://git.denx.de/?p=u-boot/u-boot-imx.git;a=commitdiff;h=6ecbe13756711baa795180d1a63b7a73a835c303;hp=da384fc67a30ff4685b679a822ef005a8f1aeaa7

i’ve integrated that into the U-Boot patch we use in the build instructions on the wiki.

Regards,

This version of the ubuntu is not working properly on my device. It is showing Windows 10 Preparing Automatic Repair Error. Please help me to fix it.

@sparowlite,

Hi @sparowlite, can you please expand on this question a little more…

Which Device? (Specific Board model)
Which OS? (Specific build/version)
Which Kernel? (uname -r)
What happens, or triggers the error?

I personally do NOT run windows day to day, so i’m confused why you linked to a “Window 10 Automatic Error”???

Regards,
