1.1 MAC Address: It is stored in fuse bank 4, with the 32 lsbs in word 2 and the
- 16 msbs in word 3.
+ 16 msbs in word 3[15:0].
+ For i.MX6SX and i.MX6UL, they have two MAC addresses. The second MAC address
+ is stored in fuse bank 4, with the 16 lsb in word 3[31:16] and the 32 msbs in
+ word 4.
Example:
bank = 4
word = 2
-And the U-boot command would be:

+2. Using imx_usb_loader for first install with SPL
+--------------------------------------------------
+
+imx_usb_loader is a very nice tool by Boundary Devices that
+allow to install U-Boot without a JTAG debugger, using
+the USB boot mode as described in the manual. It is
+a replacement for Freescale's MFGTOOLS.
+
+The sources can be found here:
+
+ https://github.com/boundarydevices/imx_usb_loader.git
+
+Booting in USB mode, the i.MX6 announces itself to the Linux Host as:
+
+Bus 001 Device 111: ID 15a2:0061 Freescale Semiconductor, Inc.
+
+imx_usb_loader is able to download a single file (u-boot.imx)
+to the board. For boards without SPL support, it is enough to
+issue the command:
+
+ sudo ../imx_usb_loader/imx_usb -v u-boot.imx
+
+In order to load SPL and u-boot.img via imx_usb_loader tool,
+please refer to doc/README.sdp.
