[meta-freescale] imxq6 sabre sd locks up when starting Qt5_Cinematic experience

[Gunnar Roth]

Dear Konstantin,
thank you very much, now the boards runs again the Qt5CinematicExperience Demo.

But i have no clue why i have to change all this (mmcroot and fdt_file) in uboot, when i build an image for this very sabresd board.
Is the other setting beneficial for anyone using this board?

Clueless,
Gunnar

Dear Gunnar,
You could try to enter in your u-boot and then do :
>editenv fdt_file
>fdt_file=imx6q-sabresd.dtb -> fdt_file=imx6q-sabresd-ldo.dtb
>saveenv
>reset
For me it works.

Best Regards,
Konstantin.
