Hi,

 

We are using i.MX8M custom board with "fsl-yocto-L4.9.51_mx8mq-ga" release.

We are getting below errors in HDMI.

 

In uboot:

*****************************************

No panel detected: default to HDMI
Display: HDMI (1920x1080)
HDMI enable failed!

*******************************************

 

In Kernel:

********************************************

[    1.179680] [drm] Initialized
[    1.189959] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[    1.196596] [drm] No driver support for vblank timestamp query.
[    1.202653] imx-drm display-subsystem: bound imx-dcss-crtc.0 (ops dcss_crtc_ops)
[    2.717769] NO HDMI FW running
[    2.720838] [drm:imx_hdp_imx_bind] *ERROR* Failed to initialise HDP PHY
[    2.727489] imx-drm display-subsystem: failed to bind 32c00000.hdmi (ops imx_hdp_imx_ops): -6
[    2.736123] imx-drm display-subsystem: master bind failed: -6

***************************************************

Looks like in both Uboot and kernel its failing in "CDN_API_CheckAlive()" function.

what may be the reason for this?

 

Thanks in advance,

Regards,

Yashavantha
