Compile imx6-ek200 with buildroot [Copy link]

Host platform: UBUNTU14.04
Hardware platform: Mingyuan Zhirui MY-IMX6-EK200
Compiler: gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz
Buildroot version: buildroot-2017.02.5.tar.bz2

1. Unzip
$ mkdir ~/IMX6/
$ tar xvf ~/IMX6/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz

$ mkdir ~/buildroot
$ cd ~/buildroot
$ tar jxvf buildroot-2017.02.5.tar.bz2
$ cd buildroot-2017.02.5/

2. Configure
$ make imx6q-sabresd_defconfig
$ make menuconfig

Use external compiler gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz
Toolchain--->
Set Toolchain type to External toolchain
Toolchain to Custom toolchain
Toolchain The path is /home/linyn/IMX6/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/.
Select

Toolchain has C++ support?

Pay attention to the setting of External toolchain kernel headers series (3.1.x). Select the kernel version number of the compiler tool. The file
~/IMX6/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/arm-linux-gnueabihf/libc/usr/include/linux/version.h
contains the version number (each compiler tool has this file). It is in decimal. You can see the version number by converting it to hexadecimal. For example, my version.h is like this
#define LINUX_VERSION_CODE 196865
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
The hexadecimal value of version 196609 is 0x30101, so the version number is 3.01.01, which is 3.0.1, so select 3.1.x here.
See the picture "Configuration 1"

System configuration--->
(myzr) System hostname Set the host name
/dev management (Dynamic using devtmpfs + mdev) Kernel configuration supports medv, and the system also configures mdev
Run a getty (login prompt) after boot --->
(ttymxc0) TTY port Set the login serial port
Baudrate (115200) ---> Baud rate

Do not compile kernel
Kernel--->
[] Linux Kernel Unselected

Do not compile U-BOOT
Bootloaders --->
[] U-Boot Unselected

$ make -j4 // Compile with 4 threads
The result is output/images/rootfs.tar
See the pictures "Result 1" and "Result 2" (Result 2 is the error reported by the kernel without compilation, regardless of it) Finally, modify the vim etc/issue

It also comes with SATA and minipcie, I think, the board is good!
