Android6.0 m6.0.1_2.0.0_ga_tool 烧写疑问

[baozhuliu]

Hi  all,

      我现在使用的是imx6qp  sabre-sd 改造过的板子，打算烧写Android6.0的系统，但是参考了Android_User's_Guide.pdf文档后还是有几点不明白的地方：

cfg.ini的配置如下：

[profiles]
chip = Linux

[platform]
board = SabreSD

[LIST]
name = eMMC-Android

[variable]
board = sabresd
mmc =0
sxuboot=sabresd
sxdtb=sdb
7duboot=sabresd
7ddtb=sdb
6uluboot=14x14ddr3arm2
6uldtb=14x14-ddr3-arm2
ldo=
soc=6q
plus=p
data_type=
folder=sabresd
initramfs=fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot
seek = 1
sxnor=qspi2
7dnor=qspi1
6ulnor=qspi1
nor_part=0

 ucl2.xml里面的

</LIST>

1，其中<CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6q%plus%%board%_sd.imx" ifdev="MX6Q">Loading U-boot</CMD>的u-boot-imx6q%plus%%board%_sd.imx我应该从哪编译得到？

2，<CMD state="BootStrap" type="load" file="firmware/zImage" address="0x12000000"里面的zImage我的编译方式如下：

$ export PATH=~/myandroid/bootable/bootloader/uboot-imx/tools:$PATH
$ cd ~/myandroid/kernel_imx
$ echo $ARCH && echo $CROSS_COMPILE
Make sure that you have those two environment variables set. If the two variables are not set, set them as follows:
$ export ARCH=arm
$ export CROSS_COMPILE=~/myandroid/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9/bin/arm-linux-androideabi-
# Generate ".config" according to default config file under arch/arm/configs.
# To build the kernel image for i.MX 6Dual/Quad, 6QuadPlus, 6DualLite, 6Solo, 6SoloLite,6SoloX, and 7Dual
$ make imx_v7_android_defconfig
$ make KCFLAGS=-mno-android

# To build the kernel uImage for i.MX 6Dual/Quad, 6QuadPlus, 6DualLite, and 6Solo
$ make uImage LOADADDR=0x10008000 KCFLAGS=-mno-android

但是每次都烧写不成功，请问imx_v7_android_defconfig是不是我烧写时所需要的文件？

3，<CMD state="BootStrap" type="load" file="firmware/zImage-imx6q%plus%-%board%%ldo%.dtb" address="0x18000000"
loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6Q">Loading device tree.</CMD>里面的zImage-imx6q%plus%-%board%%ldo%.dtb使用的是什么方式编译出来的，我该如何替换？

Hi baozhu liu,

About how to build the images runing on your board you can refer to Android_User's_Guide.pdf in the section 3 Building the Android platform for i.MX, you can see details in this document. And the uboot for mfgtool can use the same uboot for target board. Here you do not need to rebuild the uboot for mfgtool.Hope this can help you.
Have a great day,
Rita
