Hello,
My eventual goal is to get Android booted from an SD card on the Android SDK 9 on the SK-AM62-LP.
I've been able to get the boot loader up and running but every time I try to save the environment using saveenv it gives me the error of there's nowhere to save the environment:

I don't think this is a SD card boot specific issue because I had this issue trying to use the USB DFU boot and also just booting from SD card and writing to the EMMC.
I do see in the android a53 config the CONFIG_SPL_ENV_IS_NOWHERE=y flag is set, but this is not different from the regular SK config, could this be an issue?
Why am I getting this error with saveenv?
