Toolchain setup for manual U-Boot build
$ export ARCH=arm Setup the toolchain path to point to arm-eabi- tools in prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin $ export CROSS_COMPILE=//prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi-
Manual build Bootloader
Change directory to U-Boot
$ cd //bootable/bootloader/uboot-imx
Execute following commands:
clean tree: $ make mrproper Choose build for SD card or NAND flash: $ make mx6var_som_sd_android_defconfig or $ make mx6var_som_nand_android_defconfig Build U-Boot: $ make -j4
This command will generate the U-Boot images 'SPL' and 'u-boot'.
Flash newly created bootloader
To flash the newly created SPL and u-boot images, replace the following files in the recovery SD card image.
SPL Images:
SPL-nand ---------------- NAND SPL SPL-sd ------------------ eMMC / SD SPL
U-boot Images:
u-boot-var-imx6-nand.img - NAND U-boot u-boot-var-imx6-sd.img --- eMMC / SD U-boot
