imx6q调试android7问题Unrecognized filesystem type Bad Linux ARM zImage magic!

在freescale imx6q板上移植android7到时遇到一个很麻烦的问题：

用mfgtools工具下载android镜像后,启动日志：

在uboot启动时总是报错：** Unrecognized filesystem type **和

Booting from net ...FEC Waiting for PHY auto negotiation to complete......... TIMEOUT !*** ERROR: `ethaddr' not set

找了很久用prinenv可以看出boot参数乱七八糟。再看下官方给的启动参数说明，可以肯定是uboot版本编译出错：

查看本人原来为了编辑方便写的uboot编译脚本文件m.uboot.sh

root@myComputer:/home/jobs/project/myandroid/bootable/bootloader/uboot-imx# cat m.uboot.sh #!/bin/bashexport ARCH=armexport CROSS_COMPILE=/home/jobs/project/myandroid/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9/bin/arm-linux-androideabi-make distclean#To build uboot.imx that is used in Android platform#make mx6qsabresdandroid_config#To build uboot.img that is used in MFGTOOLmake mx6qsabresd_configmake

原本想编译android启动uboot却编译成了mfgtool下载用的uboot文件，查下官方给的文档说明。

将make mx6qsabresd_config改成make mx6qsabresdandroid_config就ok了！
