HDMI Black out Issue on IMX6

[vm18553]

Hi,

I'm facing HDMI blackout issue on IMX6. I'm using linux-3.10.108 kernel version. Back ported  IMX DRM patches from linux-4.10 kernel version.

I'm running following weston command

weston --tty=1 -B drm-backend.so -c weston.ini &

When I'm adding gbm-format=rgb565 in weston.ini file, HDMI blackout issue is not observed.

So, Is it always necessary to provide gbm-format=rgb565 in weston.ini file?  or this is just a workaround.

Regards,

Vishnu

Hi Vishnu

this linux version and format is not used in nxp bsp releases and

issue may be posted on meta-fsl-arm mailing list, so that someone familiar

with it could try to assist you.

In general it can be debugged using Chapter 16 On-Chip High Definition Multimedia

Interface (HDMI) Driver attached Linux Manual.

Best regards
igor
