IMX6S Display Error

giorgiosoldavin — Mon, 04 Aug 2014 10:57:57 GMT

Good morning,

I'm using Android 4.0.4 on BCM board based on IMX6S. I'm actually facing with problem on LVDS display: after at least one day running, randomly display go black (usually with orange vertical lines) but applications (checking by ADB) are still working..

The error I can catch throurgh Android Log is:

<fb_post, 184> ioctl FBIOPAN_DISPLAY failed

Can anyone please help me?

Thank you for the support.

Giorgio

Hi Giorgio

FBIOPAN_DISPLAY error is Android frame buffer error,

caused by bug on some Android ports. You may contact bcmcom.com for

more updated Android release. Alternatively you can post this to meta-fsl-arm

mailing list, so that someone familiar with this board could try to assist you.

Hi Chip,

yes, thank you; BCM already provide me a newer Android version.

I'm asking because, at the moment, I don't want to use the latest version because on actual AOSP version I've made a lot of customization that would take a lot of time to be ported on new one.

Because of this, I'm investigating if there are some patches to be applied to Android 4.0.4 that could solve the problem.

Anyway, again thank you for your reply.
