目標平臺 明遠智睿 EK314 CPU I.MAX6Q

內核版本 3.15.3

編譯器 arm-none-linux-gnueabi-gcc-4.8.3

1。下載純凈內核

2。配置Makefile

3。拷貝cp imx_v6_v7_defconfig .config

4。# make menuconfig 退出保存

5。#make zImage 進行第一次編譯，看能否通過

6。修改配置

Boot options —>

-*- Flattened Device Tree support

(noinitrd console=ttymxc0,115200) Default kernel command string

7。燒寫啟動

卡死在這里，換上正常內核，啟動對比啟動信息，發現mmc節點應該是mmcblk0，而這里在Waiting for root device /dev/mmcblk3p2…

修改uboot參數

=> setenv mmcroot /dev/mmcblk0p2 rootwait rw

=> save

=> reset

成功啟動

8。裁剪 （按個人需求）

1、去掉多余板卡支持

2、去掉聲卡支持

3、去掉 Wireless LAN

4、去掉Multimedia support —>

Remote Controller support

Remote Controller devices

Remote controller decoders

V4L platform devices —-

Cameras/video grabbers support
