-How to use and build U-Boot on mx6sabresd
------------------------------------------
-
-The following methods can be used for booting mx6sabresd boards:
-
-1. Booting from SD card
-
-2. Booting from eMMC
-
-3. Booting via Falcon mode (SPL launches the kernel directly)
-
-
-1. Booting from SD card via SPL
--------------------------------
-
-mx6sabresd_defconfig target supports mx6q/mx6dl/mx6qp sabresd variants.
-
-In order to build it:
-
-$ make mx6sabresd_defconfig
-
-$ make
-
-This will generate the SPL and u-boot-dtb.img binaries.
-
-- Flash the SPL binary into the SD card:
-
-$ sudo dd if=SPL of=/dev/sdX bs=1K seek=1 conv=notrunc && sync
-
-- Flash the u-boot-dtb.img binary into the SD card:
-
-$ sudo dd if=u-boot-dtb.img of=/dev/sdX bs=1K seek=69 conv=notrunc && sync
-
-
-2. Booting from eMMC
---------------------
-
-$ make mx6sabresd_defconfig
-
-$ make
-
-This will generate the SPL and u-boot-dtb.img binaries.
-
-- Boot first from SD card as shown in the previous section
-
-In U-boot change the eMMC partition config:
-
-=> mmc partconf 2 1 0 0
-
-Mount the eMMC in the host PC:
-
-=> ums 0 mmc 2
-
-- Flash SPL and u-boot-dtb.img binaries into the eMMC:
-
-$ sudo dd if=SPL of=/dev/sdX bs=1K seek=1 conv=notrunc && sync
-$ sudo dd if=u-boot-dtb.img of=/dev/sdX bs=1K seek=69 conv=notrunc && sync
-
-Set SW6 to eMMC 8-bit boot: 11010110
-
-
-3. Booting via Falcon mode
---------------------------
-
-$ make mx6sabresd_defconfig
-$ make
-
-This will generate the SPL image called SPL and the u-boot-dtb.img.
-
-- Flash the SPL image into the SD card:
-
-$ sudo dd if=SPL of=/dev/sdX bs=1K seek=1 oflag=sync status=none conv=notrunc && sync
-
-- Flash the u-boot-dtb.img image into the SD card:
-
-$ sudo dd if=u-boot-dtb.img of=/dev/sdX bs=1K seek=69 oflag=sync status=none conv=notrunc && sync
-
-Create a partition for root file system and extract it there:
-
-$ sudo tar xvf rootfs.tar.gz -C /media/root
-
-The SD card must have enough space for raw "args" and "kernel".
-To configure Falcon mode for the first time, on U-Boot do the following commands:
-
-- Setup the IP server:
-
-# setenv serverip <server_ip_address>
-
-- Download dtb file:
-
-# dhcp ${fdt_addr} imx6q-sabresd.dtb
-
-- Download kernel image:
-
-# dhcp ${loadaddr} uImage
-
-- Write kernel at 2MB offset:
-
-# mmc write ${loadaddr} 0x1000 0x4000
-
-- Setup kernel bootargs:
-
-# setenv bootargs "console=ttymxc0,115200 root=/dev/mmcblk1p1 rootfstype=ext4 rootwait quiet rw"
-
-- Prepare args:
-
-# spl export fdt ${loadaddr} - ${fdt_addr}
-
-- Write args 1MB data (0x800 sectors) to 1MB offset (0x800 sectors)
-
-# mmc write 18000000 0x800 0x800
-
-- Press KEY_VOL_UP key, power up the board and then SPL binary will
-launch the kernel directly.
