5. 运行 imx-mkimage 脚本生成 flash.bin 镜像:
另打开一个终端，不要与编译 uboot&kernel 同用一个终端：

pwd
~/imx-yocto-bsp/standalone
git clone https://source.codeaurora.org/external/imx/imx-mkimage
cd imx-mkimage
git tag

...
rel_imx_4.14.98_2.0.0_ga
...
git checkout rel_imx_4.14.98_2.0.0_ga
git status
HEAD detached at rel_imx_4.14.98_1.0.0_ga
imx-mkimage 需要调用 host PC 的 GCC 工具，所以需要退出之前的 terminal。重新进入，从而
退出之前 source 的交叉编译变量。
将 mx8qx-ahab-container.img, sc firmware bin, atf 和 uboot 拷贝至对应 iMX8QX 目录：

cp ../../imx8qxpmek_xwayland/tmp/deploy/images/imx8qxpmek/imx-boot-tools/mx8qx-ahab-container.img ./iMX
8QX/
cp ../packages/imx-scfw-porting-kit-1.2/src/scfw_export_mx8qx_b0/build_mx8qx_b0/scfw_tcm.bin ./iMX8QX/
cp ../imx-atf/build/imx8qx/release/bl31.bin ./iMX8QX/
cp ../uboot-imx/u-boot.bin ./iMX8QX/

运行 imx-mkimage 脚本生成 flash.bin 镜像

make SOC=iMX8QX flash_b0

结束后生成的 flash.bin 在：
./iMX8QX/flash.bin

6. 烧写镜像到 sdcard

bootloader:

vmuser@ubuntu:~$ cat /proc/partitions
major minor #blocks name
...
8 32 7761920 sdc
8 33 32768 sdc1
8 34 6918144 sdc2

sudo dd if=flash.bin of=/dev/sdc bs=1k seek=32
sync

kernel and btb:cp Image to Boot imx8qx
cp fsl-imx8qxp.dtb to Boot imx8qx
