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
Path Where to Replace Android Image: /opt/images/Android/
Sync and safely remove the SD card after replacing image.
Boot And Flash new updated bootloader
Change the DIP switch settings to SD boot mode depending upon your HW
Flash the Android images
- Note: Be careful this will wipe out your Android partitions and re-create it on eMMC / NAND.
