-U-Boot for the Congatec QMX6 boards
-
-This file contains information for the port of U-Boot to the Congatec
-QMX6 boards.
-
-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
----------------------------------
-
-Copy SPL and u-boot.img to the exported TFTP directory of the
-host PC (/tftpboot , for example).
-
-=> sf probe
-
-=> setenv serverip <server_ip_address>
-
-=> setenv ipaddr <board_ip_address>
-
-=> tftp 0x12000000 SPL
-
-=> sf erase 0x0 0x10000
-
-=> sf write 0x12000000 0x400 0x10000
-
-=> 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.
-
-It is also possible to boot from the SD card slot by using the 'bmode'
-command:
-
-=> bmode esdhc4
-
-And then the U-Boot from the big slot will boot.
-
-Note: If the "bmode" command is not available from your pre-installed U-Boot,
-these instruction will produce the same effect:
-
-=> mw.l 0x20d8040 0x3850
-=> mw.l 0x020d8044 0x10000000
-=> reset
