Yocto i.MX6 (TQIMX6) (01) : 3.14.28内核的适配
Freesacle Yocto的环境配置与编译
到Freescale下载imx6 Linux Source Code，解压里面的fsl-yocto命名的压缩包得到Yocto setup手册：Freescale_Yocto_Project_User's_Guide.pdf
然后按照里面的步骤操作即可编译出一个完整的distribution，当然很可能会因为网络或者一些Package早已不存在，或者因为大家都知道的原因而无法下载一些source code，而编译失败。
注意编译的目标选择imx6qsabresd，因为这个和我们的TQIMX6Q接近。
个人使用的步骤如下：
按照文档说明repo init会出错：
$ repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-3.14.28-1.0.0_ga fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle fatal: error [Errno 101] Network is unreachable
这是因为googlecode无法访问，所以特别指定其他的：
repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-3.14.28-1.0.0_ga --repo-url=git://codeaurora.org/tools/repo.git --repo-branch=caf-stable然后是repo sync
repo sync接着就是source env了：
MACHINE=imx6qsabresd source fsl-setup-release.sh -b imx6qsabresd_build -e wayland
Yocto中内核的移植
产生的文件位置
编译完成后内核以及rootfs以及dtb会放在相对于build目录的tmp/deploy/images/imx6qsabresd/下面
各个文件都有一个软连接来指向最新编译产生的文件。
生成uImage+dtb文件
因为使用的TQIMX6Q自带的uboot，其版本较老，其bootm命令不支持dtb加载方式启动，因此退而求其次，我们使用内核兼容的将dtb叠加到zImage后面的模式启动，对此，我们可以使用下面命令来完成：
rm uImage+dtb zImage+dtb cat tmp/deploy/images/imx6qsabresd/zImage tmp/deploy/images/imx6qsabresd/zImage-imx6q-sabresd.dtb > zImage+dtb mkimage -n imx6 -A arm -O linux -T kernel -C none -a 0x10008000 -e 0x10008000 -d zImage+dtb uImage+dtb cp uImage+dtb ~/tftpboot/imx6/
并将文件uImage+dtb放到了tftp目录下，我们将使用这个文件来启动内核。 我们将上面的脚本命名为mkuImage+dtb.sh。。
Linux 3.14.28适配TQIMX6Q板子
因为我们使用的是sabresd板子来编译的，但是我们的实际板子是TQIMX6Q，因此需要变更dts，需要变更的文件如下：
首先看到的是内核放在了哪里？ 这个是放在了如下位置，我们可以用下面命令来确定：
bitbake -e linux-imx | grep ^S=
图示：
然后我们需要将imx6q-sabresd-xxx.dts变更，这里我提供一个patch，补丁下载地址：imx6 kenel补丁，这个补丁中的dts来源于：http://axlrose.blog.51cto.com/434566/1642068
大家直接打上就可以了，打补丁的命令如下：
cd KERNEL_BUILD_SRC_DIR patch -p1 < kernel.patch
其中KERNEL_BUILD_SRC_DIR为前面说道的内核的目录。
kernel command line传入的调查
新的内核支持四种方式来组成commandline：
- 使用uboot中的
- 使用内核配置中的
- 使用uboot+内核配置中的
- 使用dtb中的chosen中的bootargs
这些都在menuconfig中可以看到，因此如果你在内核中看到的commandline与自己从uboot中传入的不一样，那么检查下面选项：
但是因为我们使用从uboot中传入，因此像上图一样配置即可。
打上补丁之后，配置好bootargs传入方式之后，我们可以再一次编译内核，并生成uImage+dtb，编译的命令如下：
bitbake linux-imx -C compile
注意这里的-C的C是大写，和小写的c是有区别的。
然后使用前面提到的命令生成uImage+dtb。
NFS文件系统创建
因为我使用的是bitbake core-image-minimal来构建系统，所有我可以按照下面命令来解压rootfs到NFS中：
tar xf tmp/deploy/images/imx6qsabresd/core-image-minimal-imx6qsabresd.tar.bz2 -C ~/nfs-imx6/yocto/
对于NFS的搭建请看我的其他博客。
启动板子
使用如下命令来启动板子：
set serverip 192.168.2.100;set ipaddr 192.168.2.111 set bootargs 'rootwait console=ttymxc0,115200n8 root=/dev/nfs nfsroot=192.168.2.100:/home/hexiongjun/nfs-imx6/yocto ip=192.168.2.120 debug ignore_loglevel init=/init vmalloc=400M video=mxcfb0:dev=hdmi,1280x720MM@60,if=RGB24,bpp=32 video=mxcfb1:off video=mxcfb2:off fbmem=48M' tftp 0x10800000 192.168.2.100:imx6/uImage+dtb;bootm 0x10800000
启动后的log如下：
