Linux not booting after cotex-m4 boot on colibri-imx7d

Hi There,

I want to enable the cortex-m4 on colibri-imx7d ,So

I saved the following command in uboot env and saved hello_world.elf in fat file system in mmc.

setenv m4boot 'fatload mmc 0:1 ${loadaddr} hello_world.elf && bootaux ${loadaddr}'
