How to disable the back light timeout on MX6DL-SABRE-SDP

[yuuki]

We operate Qt5 on MX6 DL-SABRE-SDP.

If a definite period of time passes, the back light of LCD will be turned off.
We cannot find control of a back light timeout.

Would you teach how to disable the back light timeout?

Best Regards,

Please try to pass "consoleblank=0" in your commandline bootargs.

Hi, Yuuki

     I think it should be controlled by rootfs from userspace, kernel driver only provide interface. So you can search the "fb0/blank" operation in your rootfs?
