Hi Robert,
If I plugged the HDMI cable while I started the board with the LCD cape connected the desktop is displayed on the HDMI output
On the LCD I have juste the backlight on but the touch panel is working.
I thought the HDMI should not work with my config ?
It looks like the file uEnv.txt is ignored
linux:~ # cat /boot/uEnv.txt
dtb=am335x-boneblack-emmc-overlay.dtb
bone_capemgr.enable_partno=BB-BONE-LCD7-01:00A3
I guess that would make sense, opensuse probally has their own u-boot patch..
stop u-boot, type "printenv" and figure out how to override
"dtb/dtb_file/etc.."...
dtb=xyz is one of my u-boot changes..
Regards,
Hi Robert,
Fom my understanding when I’m booting from the SD-card opensuse is using boot.script
See serial log (after modifications below)

I edit the file /boot/boot.script to use the file /boot/dtb/am335x-boneblack-emmc-overlay.dtb
→ see yellow lines below and I commented the blue lines compare to original file
But even with this modification I have no image on my LCD and if plugged the HDMI screen I see the desktop on the HDMI.
Please note the file /boot/u-boot.img is still the original one from the beaglebone opensuse image
If I use the one created with the command #make uImage dtbs LOADADDR=0x80008000 -j4 when I compile the kernel 4.1.6 the system can’t start.

X-Server is loading 4 seconds before the cape get's loaded... can you
shove the *.dtbo into the initramfs?
Regards,
Do you know how i can do that with dracut?
I don’t know why on opensuse I can’t use the mkinitrd
After loading the module when I connect in ssh I still not see the device /dev/fb0
Is it normal?
My bad the /dev/fb0 is available after loading the module.
I really need to find a way to shove the dtbo inside the initramfs.
Seems to be a decent explanation of how to do just what you want. I’ve never tested this personally though . . .
Thank you William for the link, I will try this later.
In between I found if I load the module in the /etc/init.d/boot.local the module is loaded 2-3s before X server starts
So now X found the device /dev/fb0 (see Xorg.0.log below)
But unfortunately I still have NOTHING on the display, it’s really frustrating.
The login manager lightdm process is running so I should see it on the screen.
After a while the LCD backlight turns OFF, when I touch the screen it turns back ON so I guess it’s working.
I’m using the fdt file am335x-boneblack-emmc-overlay.dtb (but I didn’t find how to check this really happeing since this parameter are loaded after the auto-boot)
I’m loading the module BB-BONE-LCD7-01-00A3.dtbo succesfully
So I tried to compare the Xorg.0.log between the opensuse and the debian which is running without issue on the eMMc with the LCD 7" 4D-CAPE-70T (wile using the same xorg.conf)
I found several differences:
On debian
II) FBDEV(0): hardware: (video memory: 750kB)
while on opensuse
II) FBDEV(0): hardware: (video memory: 2250kB)
→ I tried to override this parameter with the parameter VideoRam 750 in the device section of my xorg.conf but It has no impact the log is still the same
On debian I have several built-in extensions

I tried with am335x-boneblack-overlay.dtb it gives the same result as am335x-boneblack-emmc-overlay.dtb
I realised those files are created when we compile the kernel 4.1.6 can it be the root cause?
Hi Robert,
Do you have a suggestion how I can track down the root cause?
Is there a way to debug the module managing the LCD output since I don’t see any error on the Xorg.0.conf ?
Thanks,
Matthieu
