i.MX6dl Sabresd board won't boot with HDMI cable connected

[scottvanderweid]

I am working NXP i.MX6dl Sabresd board, trying to get Yocto Krogoth (2.1.1) up and running. If I don't have an HDMI cable (and monitor) connected the board boots fine. When I boot the board with an HDMI cable and monitor connected it fails to get passed the "Starting kernel ..." message. This happens with my build of Yocto, the FSL Community build, and the NXP reference build.

I also tried multiple DTB files ( imx6dl-sabresd.dtb , imx6dl-sabresd-ldo.dtb and imx6dl-sabresd-hdcp.dtb ). The same failure to boot occurs, except with the  imx6dl-sabresd-hdcp.dtb, which starts to boot but has a kernel panic.  Here is the output from the panic:

---[ end Kernel panic - not syncing: Fatal exception in interrupt

Does anyone have any ideas how to get the board up and running with HDMI?

Hi Scott

one can check yocto Bug 6703 - Kernel hangs on boot when HDMI cable is plugged :

https://bugzilla.yoctoproject.org/show_bug.cgi?id=6703 

and post to meta-fsl-arm mailing list

https://lists.yoctoproject.org/listinfo/meta-freescale 

Note, latest official nxp release is linux 4.1.15

i.MX 6 Series Software and Development Tool|NXP

I tried the latest build yesterday and I did not have any problems with HDMI.

Can you provide a link to your build  and/or build parameters?

It could be something about you monitor what is the monitor model? Are you using a DVI to HDMI converter?

Oliver
