 U-Boot for the Freescale i.MX6q SabreLite board
+===============================================
 
 This file contains information for the port of U-Boot to the Freescale
 i.MX6q SabreLite board.
 
-1. Boot source, boot from SD card
----------------------------------
 
-The recent mainline U-Boot for the Freescale i.MX6q SabreLite board supports
-boot from SD card only. However, by default, the SabreLite
-boards boot from the SPI NOR flash. These boards need to be reflashed with
-a small SD card loader to support boot from SD card. This small SD card loader
-will be flashed into the SPI NOR. The board will still boot from SPI NOR, but
-the loader will in turn request the BootROM to load the U-Boot from SD card.

+2. Boot from SD card
+--------------------
+
+The SabreLite boards boot from the SPI NOR flash. These boards need their SPI
+to be reflashed with a small SD card loader to support boot from SD card. The
+board will still boot from SPI NOR, but the loader will in turn request the
+BootROM to load the U-Boot from SD card.
 
 The SD card loader is available from
 
 https://wiki.linaro.org/Boards/MX6QSabreLite

+   (the default one the board is shipped with, starting from the SPI NOR) and

- MX6Q SABRELITE U-Boot > mmc read 0x10800000 0 200
- MX6Q SABRELITE U-Boot > sf probe
- MX6Q SABRELITE U-Boot > sf erase 0 0x40000
- MX6Q SABRELITE U-Boot > sf write 0x10800000 0 0x40000

-4. done.
+      sudo dd if=u-boot.imx of=/dev/sXx bs=512 seek=2 && sudo sync
 
-In case you somehow do not succeed with this procedure you will have to use
-the Freescale manufacturing tool in order to reflash the SPI-NOR.
+   Note: Replace sXx with the device representing the SD card in your system.
+
+5. Re-insert the SD card back in the slot for the large SD card and power-cycle
+   the board.
 
 Note: The board now boots from full size SD3 on the bottom of the board. NOT
       the micro SD4/BOOT slot on the top of the board. I.e. you have to use
       full size SD cards.

-2. Build
---------
 
-To build U-Boot for the SabreLite board:
+3. Boot from SPI NOR
+--------------------
 
- make mx6qsabrelite_config
- make
+The SabreLite board can also boot U-Boot directly from the SPI NOR flash:
+
+1. Power-up the SabreLite, press 'space' to enter command mode in the U-Boot
+   and enter the following commands:
+
+      => mmc dev 0
+      => mmc read 0x10800000 0x400 0x80000
+      => sf probe 0
+      => sf erase 0 0xc0000
+      => sf write 0x10800000 0x400 0x80000
+
+Note: This procedure assumes you have booted using the desired U-Boot from an
+      SD card as prepared in the previous section. Alternative mechanisms, such
+      as using tftpboot to copy an alternative U-Boot image into memory can
+      also be used.
+
+
+4. Recovering SPI-NOR
+---------------------
+
+In case you somehow do not succeed with this procedure you can upload U-Boot
+via USB:
+
+1. Download and install the imx_loader following the instructions provided:
+
+      https://github.com/boundarydevices/imx_usb_loader
+
+2. Connect the board to USB via the USB OTG port.
+
+3. Make sure SW1 switch is at position "01", so that it can boot from USB OTG.
+
+4. Power-up the SabreLite and run the imx_loader to upload the U-Boot image:
+
+      sudo imx_usb u-boot.imx
+
+Note: This will upload and run the U-Boot image in memory, the SPI will not be
+      reprogrammed and this procedure will need to be repeated if the board is
+      reset.
 
-To copy the resulting u-boot.imx to the SD card:
+5. Use one of previous descriptions to re-flash the SPI-NOR as required.
 
- sudo dd if=u-boot.imx of=/dev/sXx bs=512 seek=2&&sudo sync
+6. Ensure SW1 is returned to "00" to boot from the fuses once done.
 
-Note: Replace sXx with the device representing the SD card in your system.
