Linux/AM3358: Kernel start issue

Tool/software: Linux

Hello,

I have had a custom board designed based upon the BeagleBone Black but without many of the bulky components for a project I am working on. I have been trying to bring up the board and flash the eMMC via the SD card but I have not been successful thus far. When the board tries to boot it will get stuck in an endless cycle. Below is the output I am getting during the boot process and once it gets to the end it restarts the process all over. Could anyone give me some insight as to what might be the problem? I am new to the world of embedded systems and hardware bring up, so bare with me.
