Hi all,

It's an old port, but recently I've started getting the following error:

mxsfb 21c8000.lcdif: mxs wait for pan flip timeout

Occurs when the kernel is started after power-on.
(The kernel version is 4.1.15.)

When this error occurs, the screen becomes blank and the display becomes abnormal.
It doesn't happen every time I boot, it happens occasionally.
I think that it is likely to occur when the power is turned on after being left for a long time after being turned off.
(I don't think this will occur if the power is turned on immediately after being turned off.)


Other similar questions have been asked, but I couldn't understand what was the cause and how to solve it.

Please tell me the cause and solution.

Regards,
Koji Okuda

Do you have another panel for testing?

Hello Qmiller.

I have another panel, but so far the same phenomenon has not occurred.

Thanks & Regards,
