Yocto Build U-Boot from source code
Toolchain installation for out of Yocto builds
To install the toolchain, follow Yocto Toolchain installation.
Build U-Boot out of Yocto tree
Obtain sources:
$ git clone https://github.com/varigit/uboot-imx.git -b imx_v2015.04_4.1.15_1.1.0_ga_var03 $ cd uboot-imx
Configure compilation environment:
$ source /opt/fslc-x11/2.2.1/environment-setup-armv7at2hf-neon-fslc-linux-gnueabi
Cleanup everything:
$ make mrproper
Select one of the following configurations:
For booting from SD card/eMMC: $ make mx6var_som_sd_defconfig For booting from NAND flash: $ make mx6var_som_nand_defconfig
Build U-Boot:
$ make -j4
/*.sh scripts/pad_image.sh ..
$ cd ..
|
# Download imx_mkimage $ git clone /imx-mkimage -b $ cp imx-mkimage/iMX8M/*.c imx-mkimage/iMX8M/*.sh Morty|Morty||imx-mkimage/scripts/pad_image.sh .
}}
# Download and build ATF $ git clone /imx-atf -b $ cd imx-atf $ source /opt/fslc-x11/2.2.1/environment-setup-armv7at2hf-neon-fslc-linux-gnueabi $ export LDFLAGS= $ make PLAT= bl31 $ cp build//release/bl31.bin .. $ cd ..
# Copy u-boot binaries $ cp ../tools/mkimage mkimage_uboot $ cp ../u-boot.bin . # Build boot image $ make -f soc.mak clean $ make -f soc.mak SOC= dtbs= PAD_IMAGE=./pad_image.sh CC=gcc OUTIMG=u-boot.img-sd flash
}}
Install the built U-Boot on an SD card
$ sudo dd if=SPL of=/dev/sdX bs=1K seek=1; sync $ sudo dd if=u-boot.img of=/dev/sdX bs=1K seek=69; sync (Replace /dev/sdX with the correct device)
If you want to use our recovery SD card to flash the built U-Boot to NAND flash/eMMC, then copy it to the appropriate location in the SD card:
$ sudo cp SPL /media/rootfs/opt/images/... $ sudo cp u-boot.img /media/rootfs/opt/images/...
And eject the SD card gracefully from host machine.
Note: If you manually upgrade an existing U-Boot, and you have an old environment saved, it is a good idea to reset your environment to the new default (see Environment handling commands)
Update your U-Boot out of Yocto tree
$ git pull
