1. ubuntu unpack linux 4.14.2 compressed packet ( itop4412_kernel_4_14_2_bsp.tar.gz ) , which contains the uboot , the kernel and System .
2. In ubutnu , the process proceeds to step 1 extract from the folder ( itop4412_kernel_4_14_2_bsp ), which copy the cross compiler gcc-4.6.2-glibc-2.13- linaro-multilib-2011.12.tar.gz to ubuntu system / usr / local / arm / directory, then add the system PATH environment variable (specified directory cross compiler, reference may be set up on the cross-compilation environment manual sections) .
3. The new version of uboot increase the content of the device tree, cross-compiler compiler tools required to install the device tree, use the command: APT-GET-install Device Tree-Compiler cross compiler tool, install the device tree.
4. build a good cross-compiler environment, now entering itop4412_kernel_4_14_2_bsp directory, then run the build script in this directory
./build_all.sh
To compile uboot and kernel image, as well as the device tree ( DTB ) file
Uboot路径：u-boot-2017.11/u-boot/u-boot-iTOP-4412.bin
Path kernel: Linux-4.14.2_iTop-4412_scp / Arch / ARM / Boot / uImage
Device Path Tree: Linux-4.14.2_iTop-4412_scp / Arch / ARM / Boot / DTS / Itop-exynos4412-elite.dtb
5. Writing mirror
Development board uboot command:
Uboot2010：fastboot
Uboot2017：fastboot 0
Computer terminal fastboot tool:
fastboot.exe flash bootloader u-boot-iTOP-4412.bin
fastboot.exe flash kernel uImage
fastboot.exe flash dtb exynos4412-itop-elite.dtb
fastboot.exe flash system system.img
Writing complete restart development board can start normally.
