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,
Solved! Go to Solution.
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?
