Choosing appropriate u-boot loadaddr

KathyinCT — Fri, 16 Apr 2021 18:41:03 GMT

I'm configuring a Linux kernel for use on an i.MX7, and the settings I've configured make the kernel larger than the default settings for the boot partition. I've increased the size of the boot partition but now when u-boot tries to load the kernel it gives "Error loading kernel image"

After some searching it seems the u-boot needs to load the kernel into a larger memory location, but I'm unclear how to do this or choose the right address space? I've attached my printenv output below

=> printenv
