My custom board: reference mx6q_sabresd   BSP: L3.0.35_4.1.0     MFG tool: Mfgtools-Rel-4.1.0_130816_MX6Q_UPDATER

I download image to emmc using mfgtool. I make the board boot from fuses, but the mfgtool still display HID-compliant device.

I am sure my board would boot from emmc because I write fuses in mfgtool to make it boot from emmc, and I can see pulse in the pin of SD4_CMD.

In ud.xml, download u-boot: dd if=$FILE of=/dev/mmcblk0boot0 bs=512 seek=2 skip=2.  I enter u-boot command line in another way, and display the 100 word of the emmc from positon of 1k. I found it's different from thethe position of 1k in u-boot.bin . It's strange.
