Hi Everyone,

We are testing a custom board designed using imx6 dual processor.

 

We have modified the u-boot and device tree file as per our design. We have the kernel and rootfs on SD card.

We are loading the u-boot using mfgtool.

The code hangs after 'starting kernel'. The log is as follows:

The sd card port is USDHC2.

We have tried following few posts with the same issues, but with no success.

Please let us know the other dependencies for booting kernel image.
