How to do late initialization of LCD driver

davidzhou — Fri, 16 Feb 2018 20:32:37 GMT

I have imx6ul development board with Linux 4.15

I have implemented a splash windows through u-boot, and want to make kernel LCD driver initialization as later as possible.

The current LCD driver is initialized through:

__initcall_mxsfb_driver_init6

Is there a way to call this function through Use Space (Application)? If not, how to implement late initialization?

Thank you,

David Zhou

Hi David

I am afraid it is currently not supported and developing custom codes

may be required, probably as example one can look on implementation of

echo 0 > /sys/class/graphics/fb0/blank on

How do I prevent the LCD from turning off after 20 min ?

Best regards
igor
