Since this thread gets a lot of views, I figured I'd update it.
The issue was fixed by the following U-Boot patch:https://github.com/varigit/uboot-imx/co ... af0944b993
Also, if you want to disable video in U-Boot, remove the CONFIG_VIDEO definition here:https://github.com/varigit/uboot-imx/bl ... som.h#L482
Or, in case of the latest imx_v2017.03_4.9.11_1.0.0_ga_var01 branch, remove it from the appropriate defconfig.
e.g., in the sd defconfig: https://github.com/varigit/uboot-imx/bl ... config#L11
In general, it is best to use the latest U-Boot commit id of the latest U-Boot branch, which is currently imx_v2017.03_4.9.11_1.0.0_ga_var01:https://github.com/varigit/uboot-imx/co ... 0_ga_var01
