AM6526: SDCard, no boot issue

Part Number: AM6526

Hi,

I have two SD cards with this partition table

Device         Boot   Start      End  Sectors Size Id Type
/dev/mmcblk0p1 *       8192   212991   204800 100M c W95 FAT32 (LBA)
/dev/mmcblk0p2       212992   278527    65536 32M c W95 FAT32 (LBA)
/dev/mmcblk0p3       278528  1302527  1024000 500M 83 Linux
/dev/mmcblk0p4      1310719 29990911 28680193 13.7G f W95 Ext'd (LBA)
/dev/mmcblk0p5      1310720 15646719 14336000 6.9G 83 Linux
/dev/mmcblk0p6     15654912 29990911 14336000 6.9G 83 Linux

Both have the identical contents in /dev/mmcblk0p1 file system.

One of these SD cards will boot and the other won't.  

On the non-working media, u-boot doesn't load, there's no activity on the serial console, I'm not seeing anything; so getting some feedback on what to check would be very helpful.   This part is sitting on a Pytec SOM, if that helps at all. 

I've run fsck on the file system, no problems.  Both SD cards can be read/written.
