Hi,
With the two attached U-Boot patches plus the dts one I get the following on imx6qp wandboard:
U-Boot SPL 2017.09-37395-g28ca7c0-dirty (Sep 27 2017 - 11:04:41) Trying to boot from MMC1

A imx6q wandboard revd1 can boot well though.
Looks like an U-Boot issue. I have also tried booting a dtb + zImage from the Technexion kernel with the same result.
I am using the very same DDR init from Technexion U-Boot, so not sure why imx6qp wandboard is not lauching the kernel.
If you have any ideas, please met me know.
Thanks,
Fabio Estevam
