独立编译

Embedded Linux for i.MX Applications Processors | NXP Semiconductors

1. 编译 SCfirmware
打开一个终端：

pwd
~/imx-yocto-bsp
mkdir standalone
cd standalone
tar -xzvf imx-scfw-porting-kit-1.2.tar.gz (untar scfw tools kit)

|->packages

| |-> imx-scfw-porting-kit-1.2.bin

chmod a+x ./ imx-scfw-porting-kit-1.2.bin
sh ./ imx-scfw-porting-kit-1.2.bin (run the bin file to install scfw tools kit)
cd imx-scfw-porting-kit-1.2/src
tar xzvf scfw_export_mx8qm_b0.tar.gz
tar xzvf scfw_export_mx8qx_b0.tar.gz (untar source codes)

从以下地址 下载编译工具链：

https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads (E.g. Linux 64-bit File:

gcc-arm-none-eabi-6-2017-q2-update-linux.tar.bz2 (95.90 MB) )

注意最新验证过的工具链版本是 2017-q2，不建议使用最新的工具链。

pwd
~/imx-scfw-porting-kit-1.2
mkdir toolchain
mv gcc-arm-none-eabi-6-2017-q2-update-linux.tar.bz2 toolchain/
cd toolchain
tar jxvf gcc-arm-none-eabi-6-2017-q2-update-linux.tar.bz2
pwd
~/imx-scfw-porting-kit-1.2/src/scfw_export_mx8qx_b0
export TOOLS= ../.. /toolchain/
make qx B=mek R=B0 (如果需要看串口调试信息就增加 M=1 参数，U=2 表示使用 SCU 本身串口，注意重新
编译之前要 make clean-qx 一下)

编译结束打印为：

2. 编译 uboot：
另打开一个终端

pwd
~/imx-yocto-bsp/standalone
git clone https://source.codeaurora.org/external/imx/uboot-imx
cd uboot-imx
git tag | grep rel_imx_4.14.
....
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_2.0.0_ga
nothing to commit, working directory clean

ls configs | grep imx8qxp

…
imx8qxp_mek_defconfig
…

source ~ /imx-yocto-bsp/imx8qxpmek_xwayland/sdk/environment-setup-aarch64-poky-linux
make imx8qxp_mek_defconfig
make

编译 log 如下：

…

LD u-boot
OBJCOPY u-boot.srec
OBJCOPY u-boot-nodtb.bin
start=$(aarch64-poky-linux-nm u-boot | grep __rel_dyn_start | cut -f 1 -d ' '); end=$(aarch64-poky-linux-nm u-boot |

编译结束后的输出镜像为：
u-boot.bin
arch/arm/dts/fsl-imx8qxp-mek.dtb

3. 编译 Linux 内核：

pwd
~/imx-yocto-bsp/standalone
git clone https://source.codeaurora.org/external/imx/linux-imx
cd linux-imx
git tag |grep rel_imx_4.14

...
rel_imx_4.14.98_1.0.0_ga
...
git checkout rel_imx_4.14.98_2.0.0_ga
git status
HEAD detached at rel_imx_4.14.98_2.0.0_ga

source ~ /imx-yocto-bsp/imx8qxpmek_wayland/sdk/environment-setup-aarch64-poky-linux
make defconfig
LDFLAGS="" CC="$CC" make 
LDFLAGS="" CC="$CC" make dtbs clean
LDFLAGS="" CC="$CC" make dtbs //just make dtb

编译结束后的输出镜像为：
arch/arm64/boot/dts/freescale/fsl-imx8qxp-mek.dtb
arch/arm64/boot/Image

4. 编译 ATF:

pwd
~/imx-yocto-bsp/standalone
git clone https://source.codeaurora.org/external/imx/imx-atf
cd imx-atf
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_2.0.0_ga

source ~/imx-yocto-bsp/imx8qxpmek_wayland/sdk/environment-setup-aarch64-poky-linux
LDFLAGS="" make PLAT=imx8qx

编译 log 为：
…
LD build/imx8qxp/release/bl31/bl31.elf
BIN build/imx8qxp/release/bl31.bin
Built build/imx8qxp/release/bl31.bin successfully
编译结束后的输出镜像为：
./build/imx8qxp/release/bl31.bin

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

include misc.mak

include m4.mak
include android.mak
include test.mak
include autobuild.mak
include rev_a.mak

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
