Hi all,
I am using imx287 processor based board for one of my Infotainment project. Interfaced tm035kdh04 panel to the board. Using third party graphic library, I am able to display the images on display. I am facing the below issue with the display,Please can any one suggest how to fix this issue.
The display becomes white for every 10 mints. If I touch the keypad present on the board, screen becomes normal.

Disabling CONFIG_VT_CONSOLE will not affect other peripheral functionality.
Instead of Disabling CONFIG_VT_CONSOLE, you can set "consoleblank=0" at kernel command line to disable VT auto blank feature. See https://community.freescale.com/docs/DOC-100108
Hi ashok,
The solution in this post https://community.freescale.com/thread/323250 may also help you as well.
Thanks for you quick reply.
I tried by disabling the config_vt_console option in the kenel, and verified display is not going blank for every 10 minutes.
Please can you clarify on below two things.
if the config_vt_console disabled, will it affect any other functionality of the peripheral of a board?
Instead of disabling the config_vt_console, can we handle this as part of panel driver?

Thanks for your reply.
I already verfied this option(consoleblank=0) also. Either way it is working fine.
Hi ashok
How do I prevent the LCD from turning off after 20 min ?
also one can try this command for turning off the FB blanking
echo -e "\033[9;0]" > /dev/tty0
If you have screensaver, sometimes screensaver shuts down the LCD.
Best regards
igor
