+U-Boot for the Congatec QMX6 boards
 
 This file contains information for the port of U-Boot to the Congatec
-Conga-QEVAl Evaluation Carrier board with qmx6 quad module.
+QMX6 boards.
 
-1. Boot source, boot from SD card
+1. Building U-boot
+------------------
+
+- Build U-boot for Congatec QMX6 boards:
+
+$ make mrproper
+$ make cgtqmx6eval_defconfig
+$ make
+
+This will generate the following binaries:
+
+- SPL
+- u-boot.img
+
+2. Flashing U-boot in the SPI NOR
 ---------------------------------
 
-By default, the Congatec board can boot only from the SPI-NOR.
-But, with the u-boot version provided with the board you can write boot
-registers to force the board to reboot and boot from the SD slot. If
-"bmode" command is not available from your pre-installed u-boot, these
-instruction will produce the same effect:
+Copy SPL and u-boot.img to the exported TFTP directory of the
+host PC (/tftpboot , for example).
+
+=> sf probe
+
+=> tftp 0x12000000 SPL
+
+=> sf erase 0x0 0x10000
+
+=> sf write 0x12000000 0x400 0x100
+
+=> tftp 0x12000000 u-boot.img
+
+=> sf erase 0x10000 0x70000
+
+=> sf write 0x12000000 0x10000 0x70000
+
+Reboot the board and the new U-boot should come up.
+
+3. Booting from the SD card
+---------------------------
+
+- Flash the SPL image into the SD card:
+
+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
+
+- Flash the u-boot.img image into the SD card:
+
+sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
+
+- Insert the SD card into the big slot.
+
+The boot medium of Congatec QMX6 boards is the SPI NOR flash, so boot
+the board from SPI first.
 
-conga-QMX6 U-Boot > mw.l 0x20d8040 0x3850
-conga-QMX6 U-Boot > mw.l 0x020d8044 0x10000000
-conga-QMX6 U-Boot > reset
-resetting ...
+It is also possible to boot from the SD card slot by using the 'bmode'
+command:
 
-The the board will reboot and, if you have written your SD correctly
-the board will use u-boot that live into the SD
+=> bmode esdhc4
 
-To copy the resulting u-boot.imx to the SD card:
+And then the U-boot from the big slot will boot.
 
- dd if=u-boot.imx of=/dev/xxx bs=512 seek=2
+Note: If the "bmode" command is not available from your pre-installed U-boot,
+these instruction will produce the same effect:
 
-Note: Replace xxx with the device representing the SD card in your system.
