i.mx6q emmc

1、barebox

Android BSP包关于i.MX6DL emmc板的barebox镜像仍有些问题，用linux上的barebox替换。

...

i.mx6q emmc barebox镜像：ftp://ftp.phytec.cn/i.MX6/BSP-Yocto-i.MX6-PD16.1.0/images/phyboard-mira-imx6-5/barebox.bin

2、oftree

i.mx6dl emmc :

设备树文件：imx6dl-phytec-mira-rdk-emmc.dts

修改后需要重新编译内核即可。

i.mx6q emmc :

修改后重新编译内核即可。

3、kernel

kernel image位置：kernel/arch/arm/boot/zImage

对于imx6q emmc核心板，内核需要打这个补丁：0001-mmc-core-Update-the-ext-csd.rev-check-for-eMMC5.1.patch

4、android system

修改BSP包的vendor/SIGMA/miraq/BoardConfig.mk文件，将系统镜像匹配为ext4格式，系统镜像默认为nand的ubifs格式

...

android 系统镜像的位置：bdir/android_imx/target/product/miraq/system.img

5、制作emmc镜像

android BSP包有一个可以生成SD卡镜像的工具：vendor/SIGMA/miraq/tools/gen_sd_img.sh，使用该工具来生成emmc的镜像。

...

在当前目录下生成sd.img, 该镜像就是emmc的镜像,将该镜像复制到sd卡上。

6、烧写android镜像。

开发板开机进入到barebox, 插入有emmc镜像的SD卡，
