IMX6 SOLO only boots with SPL

I'm seeing something strange and hopefully someone can explain it to me.  We have a custom board that has been populated with a SOLO, DUAL, and QUAD.  I've noticed that if I flash u-boot.imx onto an SD card or the eMMC (at location 0x400), it will boot up just fine on the DUAL and QUAD boards.  However, if I try the exact steps on the SOLO board, it will not boot.  If I place an SPL at 0x400 (the SPL image was taken from Solid-Run:, and ), the SOLO board will boot, load u-boot.img, and continue to boot up just fine.


Any ideas what the difference would be between a SOLO and DUAL/QUAD?  The boot configurations are identical on all three, and I've confirmed with the Lauterbach that the SBMR registers are the same.  So what gives?


I'm using buildroot, and the U-Boot sources are taken from here: git://, and on branch rel_imx_4.1.15_2.0.0_ga, so I know that I'm using an up-to-date version of u-boot.  I've created a custom board file copied from /board/freescale/mx6sabersd.
