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...
