Hi JCon St,

Can you let us know which version of iMX Linux User Guide are you following?

After partitioning the card, please verify that you have copied Bootloader, Kernel image & dtb, and root filesystem to the card. Also, make sure the boot switches on the EVK board are set to boot from SD card. 

Download the iMX Linux User Guide and iMX Yocto User Guide from this link.

Regards,

Karan Gajjar
