IMX53 uboot issue

I am working with a custom board based on the MX53QSB (MCIMX53-START-R). The only difference is the USB OTG has been omitted. The custom board boots fine with the MCIMX535-START-R-BSP-11-09_C image, but the core-image-minimal build from yocto (using the IMX53QSB machine on Daisy) does not boot. The following is output when trying to boot from the core-image-minimal build:


"U-Boot 2013.10 (Sep 17 2015 - 15:22:06)

It appears that the yocto uboot build doesn't see the SDcard. I used the MCIMX535-START-R-BSP-11-09_C image to check the fuse settings on the MCIMX53-START-R board and burnt the same fuses on the custom board. I've used the OBDS tools in the MCIMX535-START-R-BSP-11-09_C image to test out the peripherals, and everything seems to be operational hardware wise. Does anyone have any insight as to why the yocto uboot isn't seeing the sdcard?
