全志v3s学习笔记（6）——Bsp内核编译与烧录
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
如果不想被坑卓坑， 又想比較好地使用攝像頭，可以使用主線Uboot加Bsp內核方案， 系統配置為fex文件配置。
主線uboot： https://github.com/Lichee-Pi/u-boot
bsp內核： http://pan.baidu.com/s/1eRJrViy
一、安裝交叉編譯環境
交叉編譯環境跟uboot使用的一樣。
參考：arm-linux-gnueabihf 交叉編譯工具鏈安裝
二、下載bsp內核源碼
bsp內核： http://pan.baidu.com/s/1eRJrViy
linux-3.4是bsp內核源碼。
三、修改頂層Makefile
在內核根目錄下的Makefile195行修改默認編譯器，可以直接用make編譯：
# ARCH ?= $(SUBARCH) # CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%) ARCH ?= arm CROSS_COMPILE ?= arm-linux-gnueabihf-四、內核配置修改
使能USB攝像頭驅動：
Device Drivers ---><*> Multimedia support ---> [*] Video capture adapters ---> [*] V4L USB devices ---> <M> USB Video Class (UVC)使能DVP/MIPI攝像頭：
Device Drivers ---><*> Multimedia support ---> [*] Video capture adapters ---> [*] V4L platform devices ---> <*> SoC camera support<M> ov2640 camera support<M> sunxi video front end (camera and etc)driver<M> v4l2 driver for SUNXI添加ext4支持:
File systems ---><*> The Extended 4 (ext4) filesystem[*] Useext4 for ext2/ext3 file systems[*] Ext4 extended attributes[ ] Ext4 POSIX Access Control Lists[ ] Ext4 Security Labels[ ] EXT4 debugging support[ ] JBD2 (ext4) debugging support添加CONFIG_LBDAF支持：
（大文件支持，否則無法掛載文件系統）:
[*] Enable the block layer ---> [*] Support for large (2TB+) block devices and files添加CGROUPS支持：
General setup --->[*] Control Group support --->五、編譯
lichee_BSP_config配置修改了內核支持網口 支持ext4文件系統
cd linux-3.4 cp lichee_BSP_config .config make uImage -j16 # 如果使用 make -j16 會生成 zImage make -j16 INSTALL_MOD_PATH=out modules # 編譯出模塊 make -j16 INSTALL_MOD_PATH=out modules_install # 安裝模塊uImage 在 arch/arm/boot/uImage目錄
六、TF卡燒錄
準備好之前生成的boot.scr和script.bin，和剛生成的uImage一起放到TF卡第一分區。
參考：u-boot傳參(boot.scr)和參數配置(script.bin)文件
七、輸出LOG：
如果 ext4 掛載出錯請參考：
【問題解決】報錯：EXT4-fs (mmcblk0p2): couldn‘t mount RDWR because of unsupported optional features (400)
這是已經掛載了根文件系統的LOG：
