Hi Community,

I'm working on i.MX6 Quad sabre-SD cpu and build Android 6 as my image.


As I have a customize boot logo so I had modified and added some files below.


In kernel/drivers/video/logo I add a new ppm picture named "logo_forenex_clut224.ppm" and it's for 1920x1080 resolution.

Then I added below content in kernel/drivers/video/logo/Kconfig and Makefile.


bool "224-color Forenex logo"
default y


obj-$(CONFIG_LOGO_FORENEX_CLUT224)      += logo_forenex_clut224.o

Then added below content in kernel/include/linux/linux_logo.h.


extern const struct linux_logo logo_forenex_clut224;//forenex victor add


Then I added below content in kernel/drivers/video/logo/logo.c.


logo = &logo_forenex_clut224;


After added all this files I had added boundary patch in this website.

kernel bootlogo on hdmi 


After finished all this works I built it and success.

Consequently I update image to my machine and boot up.

Unfortunately HDMI still not show boot up logo and just show Android animation logo only.


How can I fix this issue?

Did I miss any step?

Is there any additional settings that I have to mentioned in menuconfig?


Thanks in Advanced!
