fitImage loadaddress and entrypoint for imx8mn evk

[vinothkumars]

Dear NXP,

I am working on fitImage creation for IMX8MN-EVK platform for yocto software.

I able to create the fitImage and boot by bootm command. But, it's stopped before kernel start and continuous reboot.

Will you please tell which address (load and entry point) I have to give for fitImage which is have the initramfs,dtb and kernel

FitImage loadaddress depends on the image size.

By default,

loadaddress (from source) => 0x40480000

Image (FitImage = kernel + dtb + Initramfs ) size is increased=>148 Mb = 0x9400000

So the load address of fitImage is = loadaddress + Image size is increased

                                                       = 0x49880000

Loadaddress of fitImage is (abbrox) = 0x50000000 and above we can give.
