Hello
Device: jetson nano devkit emmc
Jetpack version: 4.6.3
Display: Same as shown in the picture
I want to rotate cboot logo.
I know that I need to modify the dts file to rotate the cboot logo, but don’t know how to fix it.
Could I have any advice?
Hi,
You may consider using frame buffer rotation:
Hi WayneWWW Thank you for response.
I tried this before, but it didn’t work.
Add CONFIG_FRAMEBUFFER_CONSOLE_ROTATION=y in kernel-4.9/arch/arm64/configs/tegra_defconifg and rebuild it (fbcon_rotate.c build ok)
Copy Image and dtb file to kernel folder
flash to device
connect to the device, move to /sys/class/graphics/fbcon
echo 1 > rotate
The result is ‘-bash: rotate: Permission denied’
Am I missing something?
Do it like this:
sudo sh -c “echo 1 > rotate”
error does not occurred but cat rotate result is ‘0’
Then would it work if you put it as kernel command line in extlinux.conf?
I put ‘quiet fbcon=rotate:3’ in /boot/extlinux.conf
cat /sys/calss/graphics/fbcon result is ‘3’
But cboot logo still print like picture.
Only boot log rotate
Hi,
Sorry for my previous comments.
Anything about rotating the monitor/boot logo or forcing EDID can only be done after Linux kernel takes over in the booting process, and they are not supported in Cboot so what you are trying to do is not possible.
Oops…
Then is there a way to display Ubuntu logo in just one window?
Now, the logo is expanded and displayed on two screens.
