盈鹏飞嵌入式---OpenWRT在iMX6UL上面的移植与编译

选择

OpenWRT在最近的时期分裂出了LEDE出来，因此这就涉及到了这两个的选择。

前段时间，编译过LEDE用于树莓派3，于是想着直接使用以前的LEDE，这样子省去了下载，毕竟在国内下载很多source code可能需要很长的时间，如果没有proxy的话。于是想着省些事情就用起来了以前的LEDE来编译,但是编译过程中出现了很多错误， 因此最终我决定切回到OpenWRT，并且使用master上面新的代码来移植编译。

代码仓库：http://www.dwz.cn/5MODVb

OpenWRT配置

本身LEDE与OpenWRT里面已经有一个imx6 Cortex-A9的arch支持，因此直接选择这个为base来做Porting与Compile较为合适。配置如下：

Compile Tuning

因为imx6ul是Cortex-A7，所以我们需要更改一下

选择好Target之后，我们需要做移植工作。

Target移植 内核移植

移植需要将内核更改一把，这个位于：

$ ls target/Linux/imx6/
base-files  config-3.14  config-4.4  files-4.4  image  Makefile  patches-4.4  profiles

其中config-XX是内核的.config文件，注意不要有modules，全部用builtin，否则将会出错。

然后patches-XX是对应内核的patches，我们不需要这些东西，所以不需要。

内核位置的指定

然后直接编译make即可。

编译的错误 1. DEPEND的问题

如果使用Prebuilt的toolchain可能会出现下面这个问题：

Package libnl-tiny is missing dependencies for the following libraries:
libc.so.6

那么就需要将libc.so添加到DEPENDS变量中。

2. 内核编译错误

内核比较老，但是GCC版本较高，会出现下面这个错误：

[html] view plain copy

• init/do_mounts_rd.o: In function `nop_flush_icache_all':  
• do_mounts_rd.c:(.text+0x0): multiple definition of `nop_flush_icache_all'  
• init/do_mounts.o:/ExtDisk/Projects/iMX6UL_OpenWRT/BSP_EVB/linux_3.14/init/do_mounts.c:610: first defined here  
• init/do_mounts_rd.o: In function `nop_flush_kern_cache_all':  
• do_mounts_rd.c:(.text+0x4): multiple definition of `nop_flush_kern_cache_all'  
• init/do_mounts.o:/ExtDisk/Projects/iMX6UL_OpenWRT/BSP_EVB/linux_3.14/init/do_mounts.c:610: first defined here  
• init/do_mounts_rd.o: In function `nop_flush_kern_cache_louis':  
  

要解决这个问题，需要在内核的CFLAG中添加 -fgnu89-inline

这个问题可以参考：

  http://unix.stackexchange.com/questions/250804/error-while-building-linux-kernel-for-versatile-board

3.内核编译的错误2

[cpp] view plain copy

• ERROR: module '/openwrt/build_dir/target-arm_cortex-a9+neon_musl-1.1.16_eabi/linux-imx6/linux-3.14/drivers/usb/gadget/udc/udc-core.ko' is missing.  
  

出现问题是因为我们没有正确的配置kernel module对应的item，但是因为我们暂时不需要，所以直接将其干掉即可：

4. 并发编译出错

一般都是因为make的时候指定-jN的N过大导致。

5. 环境编译问题

编译的时候出现：

[plain] view plain copy

• Usage:   
•         cp [options] FILE DEST  
•         cp [options] FILE1 [FILE2 ...] DEST-DIR  
•         cp --help for options list  
•          
• cp: error: no such option: -p  
• make[3]: *** [/ExtDisk/Projects/WRTNode/staticSDK/build_dir/host/patch-2.7.1/.configured] Error 2

• make[1]: Leaving directory `/ExtDisk/Projects/WRTNode/staticSDK'  
• make: *** [world] Error 2  
  

一般是因为安装了gcp导致的，所以remove掉gcp即可。
编译的结果产物

位于bin下面：

这里面我们使用generic的rootfs即可。

然后我们使用zImage而不是uImage，这个位于：

build_dir/target-arm_cortex-a9+neon_musl-1.1.16_eabi/linux-imx6/zImage

dtb位于：

build_dir/target-arm_cortex-a9+neon_musl-1.1.16_eabi/linux-imx6/linux-3.14/arch/arm/boot/dts/imx6ul-14x14-evk.dtb

启动

将zImage与dtb拷贝到tftp directory，然后将rootfs解压到SD卡，使用SD卡作为rootfs。然后就可以使用下面这些命令来启动了。

[plain] view plain copy

• set serverip 192.168.1.100  
• set bootargs 'console=ttymxc0,115200 ip=192.168.1.120 root=/dev/mmcblk0p2 rootwait'  
• tftp 85800000 imx6ul_openwrt/imx6ul-14x14-evk.dtb; tftp 83800000 imx6ul_openwrt/zImage;bootz 83800000 - 85800000  
  

启动后发现buzzer不停的叫着，显然这个是因为内核dts配置有问题， 因此我们先使用默认的kernel + dtb先启动，以后再继续更改内核。启动参数为：

[plain] view plain copy

• set serverip 192.168.1.100  
• set bootargs 'console=ttymxc0,115200 ip=192.168.1.120 root=/dev/mmcblk0p2 rootwait'  
• run bootcmd  
  

启动后的log如下，放在下面为以后可能有需要的做对比和参照
