I.mx6ul--A detailed explanation of Linux system porting process

Development platform: Zhuhai Ding-core D518--based on I. MX 6UL Latest System: u-boot2015.04 + linux4.1.15_1.2.0 cross-compilation tool: DCHIP-LINARO-TOOLCHAIN.TAR.BZ2

Source Download Address:

U-boot: (select rel_imx_4.1.15_1.2.0_ga.tar.bz2)

http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/

Kernel: (select rel_imx_4.1.15_1.2.0_ga.tar.bz2)

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/

Source Code porting process:

1, the Linux kernel and uboot source code copy to the Ubuntu12.04 system in the Dchip_imx6ul directory;

2, use the TAR command to extract the Uboot and kernel to the Dchip_imx6ul directory;

3, after decompression into the Uboot directory, the new file make_dchip_imx6ul_uboot201504.sh, and the contents of the file are as follows:

###################################################################

# build u-boot.2015.04 to D518--i.mx6ul by FRESXC #

###################################################################

#!/bin/bash

Export ARCH=arm

Export Cross_compile=<yourpath>/dchip-linaro-toolchain/bin/arm-none-linux-gnueabi-

make Mrproper # means clean

make Mx6ul_14x14_evk_defconfig

make 2>&1|tee built_dchip_imx6ul_uboot201504.out

Enter the kernel directory, create a new file make_dchip_imx6ul_linux4115120.sh, and the contents of the file are as follows:

###################################################################

# build Linux-4.1.15 Ford518--i.mx6ul by FRESXC #

###################################################################

#!/bin/bash

Export ARCH=arm

Export Cross_compile=<yourpath>/dchip-linaro-toolchain/bin/arm-none-linux-gnueabi-

make Mrproper # means clean

make Imx_v7_defconfig

make uimage loadaddr=0x100080002>&1|tee built_dchip_imx6ul_ Linux4115120.out

make IMX6UL-14X14-EVK.DTB

After the above section, in the terminal into the kernel and Uboot source directory, the use of./make_dchip_imx6ul_uboot201504.sh

and the./make_dchip_imx6ul_linux4115120.sh command to run the two script files above. This will allow the compilation to succeed.
