BBB OpenSuse 13.2 no video output

Hi,

The BBB is running fine under the Debian image on the eMMC
I have been able to use on several displays through the uHDMI connector and also using the 4DCAPE-70T LCD
So I’m sure my hardware is OK.

For a new project I need to use OpenSuse on the BBB.

I have tested the latest 13.2 images
openSUSE-13.2-ARM-JeOS-beaglebone.armv7l-1.12.1-Build33.5.raw.xz

openSUSE-13.2-ARM-XFCE-beaglebone.armv7l-1.12.1-Build33.8.raw.xz

OpenSuse is booting and I’m able to connect to the board through SSH but I’m not able to have video on the HDMI output or on the 4DCAPE-70T which is my goal.

Under JeOS I tried the following

I install this package
xf86-video-omap | X.Org X server – Omapdrm display driver

which has installed the following 97 packages

Mesa Mesa-libEGL1 Mesa-libGL1 Mesa-libglapi0 bundle-lang-common-ar cpp cpp48 esound-daemon fontconfig fonts-config

But the screen is not found see Xorg log below.

If somebody has an advice to help it will me great.

Thanks in advance,

Well... The am335x used on the beaglebone black, does not have the
"omap" display ip block. Use fbdev as modesetting is to unstable.

Then grab this xorg.conf

I have the wrong config

CONFIG_DRM_I2C_NXP_TDA998X=m
linux:/home # zcat /proc/config.gz | grep TILCD
CONFIG_DRM_TILCDC=y

I do not find the folder /usr/src/linux and the make command is not install, this JeOS version is really thin.

Should I use the XFCE image?

I really appreciate your help, do you have a link who explain how to set properly the kernel on the BBB?

Thanks,

Matthieu

We have a tested git repo with config here:

https://github.com/beagleboard/linux/tree/4.1

config: bb.org_defconfig

Hi,

Sorry I was quite busy but I have finally been able to compile the kernel 4.1 on opensuse 13.2 running on the BBB but I’m not able to boot on it
→ nothing displays on the screen
→ board is not showing on the network
→ if I check /var/log/messages when I boot on the Debian (eMMC) there is no log, I saw only the latest successful boot on the old kernel 3.16.7-11-default

To summarise:

I copied the https://github.com/beagleboard/linux/tree/4.1 in the /home/ folder and execute the following commands.

linux:/home/linux # make bb.org_defconfig

linux:/home/linux # make -j4

linux:/home/linux # make uImage dtbs LOADADDR=0x80008000 -j4

linux:/home/linux # make modules -j4

linux:/home/linux # make modules_install

linux:/home/linux # make install

See attached for your reference the logs for thoses commands
→ several modules can’t be installed but I think it’s normal considering the configuration

Then I copy to /boot folder /home/linux/arch/arm/boot/uImage rename uImage_4.1.6
copy */home/linux/*arch/arm/boot/dts/am335x-boneblack.dtb to /boot/dtb/
and create the symlink for

  • zImage
  • u-boot.img
  • initrd
    see below

image.png

The good news is that I’m able to reboot on my old kernel if I change the symlinks to point to the 3.16.7 versions.

I’m probably missing a step to configure the boot, if you have an idea.

Thanks in advance for the help,

yeah... a 'serial' boot log is always useful, instead of just guessing
what's happening at bootup. :wink:

If that's it... You have 'other' issues to fix first..

before we even talk about telling u-boot which kernel file to load..

Regards,

11

I have tried something which is working.

I used the original u-boot.img from the opensuse 13.2 instead of using the one I created with the command #make uImage dtbs LOADADDR=0x80008000 -j4
But I used the zImage and initrd I have generated when I install the 4.1.6

image.png

I booted succesfully on opensuse 13.2 with the kernel 4.1.6

linux:~ # cat /proc/version

Hi,

The HDMI output is working.

No I’m trying to use the LCD output using the 4DCAPE-70T LCD

I found 2 threads who described the same issue
BBB and LCD7 under Ubuntu in my own applications: is it practical?
BBB Debian 4.1 Jessie and 4DCAPE-43T

I created the file uEnv.txt

linux:~ # cat /boot/uEnv.txt

dtb=am335x-boneblack-emmc-overlay.dtb

When I restart the system opensuse i booting but the LCD is OFF

How about:

dmesg | grep bone

(cape doesn't show everything.)

Make sure you used the new "dtc"

https://github.com/beagleboard/bb.org-overlays

Regards,

14

dmesg | fgrep bone shows the same as fgrep cape.

i will check the dtc I need to find how to apply it on opensuse I’m really not familiar with this part.

15

If it's not dtc 1.4.1-gXXXXXXX

then:

build this version:

https://github.com/pantoniou/dtc

branch: dt-overlays5

hopefully it'll hit dtc master at some point. :wink:

Regards,

16

Hi Robert,

I installed the dtc from git

linux:/home/linux # /usr/local/bin/dtc --version

Version: DTC 1.4.1-g47216cdb

I checked the requirements
linux:~ # zcat /proc/config.gz | grep CONFIG_BONE_CAPEMGR
CONFIG_BONE_CAPEMGR=y

I skipped the kernel update since I’m running the 4.1.6, installed last week, and the /opt/scripts/tools/update_kernel.sh is written for debian.
→ Is it Ok ?

Then I downloaded the bb.org-overlays
#git clone https://github.com/beagleboard/bb.org-overlays /home/bb.org-overlays

Since the install.sh script was written for debian I have run the commands
# make clean
# make
# make install (see details logs below)

Now I have the file /lib/firmware/BB-BONE-LCD7-01-00A3.dtbo

Since update-initramfs is not available on opensuse I run the dracut command

# dracut -f /boot/initrd-4.1.6_bis (see details log below)

I updated the initrd symlink
linux:/boot # ln -sf initrd-4.1.6_bis initrd

But when I reboot the firmware is still not loaded any idea?

I tried to load the firmware manually but it doesn’t work

linux:/sys/devices/platform/bone_capemgr # echo BB-BONE-LCD7-01>slots
-bash: echo: write error: No such file or directory

Best regards,

Since you are dealing with a versioned overlay:

echo BB-BONE-LCD7-01:00A3 > slots

Regards,

19

Thanks the LCD is living.

Any advice how can I do echo BB-BONE-LCD7-01:00A3 > slots during the startup before we launch the desktop?
