Kernel hangs on Imx8m

Hello (again) support team,
we have developed a proprietary board derived from the NXP evaboard imx8mqevk.
The DDR memory format has changed to 2GB.

The kernel boots but hangs. Someone could give me some tips?

 

Yocto version is Zeus (imx-5.4.24-2.1.0)
the machine is "fsl-image-machine-test"
the distro is "fsl-imx-wayland"
The boot output:

Hello,

By your previous thread I see that you made changes accordingly to dts in uboot, but you need to do the same in your Linux dts and configuration.

As Igor stated you may refer to the i.MX8MMini EVK which have the same DDR size and change the configuration accordingly.

Best regards,
Aldo.
