Yes. If you program u-boot.imx to offset 0x400, it will boot.

I just did so as shown below.

I started by placing SW1 in the 01 position (boot to USB), and
used imx_usb to dowload u-boot.imx:

     MX6QSABRELITE U-Boot>  dhcp 10800000 192.168.0.112:u-boot.imx
     fec_open:Speed=100
     BOOTP broadcast 1
     BOOTP broadcast 2
     DHCP client bound to address 29.6.1.24
     Using FEC device
     TFTP from server 192.168.0.112; our IP address is 29.6.1.24;
     sending  through gateway 29.6.1.1
     Filename 'u-boot.imx'.
     Load address: 0x10800000
     Loading: #########################################
     done
     Bytes transferred = 207112 (32908 hex)
     MX6QSABRELITE U-Boot>  sf write 0x10800000 0x400 $filesize

But above you used the network to load u-boot.imx. With imx_usb you
loaded and booted an image via USB first, I assume.

Yeah. USB to execute U-Boot, then Ethernet to get a pristine
image into RAM for programming.

I'd love to get USB support for MX6Q into U-Boot, but that's another
project...
