Dear all,
We are working on imx8qm-mek running on Android 9 - auto. I have gone through the couple of posts from this forum regarding HDMI-RX functionality.
I have used fsl-imx8qm-mek-hdmi-in.dts as reference and modified fsl-imx8qm-mek-car.dts. After flashing completed build on MEK platform i am receiving below log.
[ 4.424144] [drm:hdmirx_init] *ERROR* NO HDMI RX FW running
[ 4.429740] mxc-hdmi-rx 58268000.hdmi_rx: mxc hdmi rx init failed
s[ 4.435919] mxc-hdmi-rx 58268000.hdmi_rx: mxc hdmi rx probe failed
So here i see that HDMI RX FW is not running and so the error is thrown.
I found the firmware are locate here :
vendor/nxp/linux-firmware-imx/firmware/hdmi/cadence/hdmirxfw.bin
vendor/nxp-opensource/imx-mkimage/iMX8QM/hdmirxfw.bin
I need to understand how i can use these firmware to resolve the above issue ? It will be great if someone can throw some light here.
Solved! Go to Solution.
