iMX8QM Yocto Logo Rotation

prashanthkumar — Sat, 23 Feb 2019 08:26:39 GMT

Hi,

We are working on iMX8QM custom board with L4.14.78 Kernel BSP, in which yocto boot logo is coming up-side down (showing open-embedded as LOGO) in MIPI-DSI LCD while booting kernel.

We need to rotate that yocto boot logo to 180 degree.

Is there any way/command to change rotation/flip the yocto logo/image whle booting?
Kindly let me know the fix for logo rotation issue

Best Regards,
Prashanth Kumar K

You can go to path

sources/meta-fsl-bsp-release/imx/meta-bsp/recipes-core/psplash/files/psplash-basic.service

and change

[Service]
ExecStartPre=/bin/sh -c "if [ -e /sys/class/graphics/fbcon/cursor_blink ]; then echo 0 > /sys/class/graphics/fbcon/cursor_blink; fi"
ExecStart=/usr/bin/psplash --angle 90 -n

angle 90 is for 90 degree rotation, you may change as you wish
