ZYNQ：使用PetaLinux打包 BOOT.BIN、image.ub
说明
个人还是比较喜欢灵活去管理各个部分的源码。
有关文章：
ZYNQ：PetaLinux提取Linux和UBoot配置、源码
编译Linux
取得Linux源代码和配置后，可以在其中执行make，编译Linux。
注意，编译前请导入PetaLinux环境变量：
- 设置和导出ARCH为arm或者arm64；
- 设置和导出CROSS_COMPILE，比如aarch64-linux-gnu-。
编译（通过，但是diff 有差异）：
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- xilinx_peta_defconfig
# xilinx_peta_defconfig 是 我们前文拷贝 .config 得来的。
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j 2
编译后得到vmlinux
打包 image.ub
将kernel、dtb、rootfs.img打包成image.ub。
kernel：一般就是linux生成的elf文件。dtb：设备树，与驱动有关。rootfs.img：编译完成的文件系统。
所以，image.ub 没有那么神秘，就是一个包。
使用以下命令：
#!/bin/sh
CROSS_COMPILE=arm-linux-gnueabihf-
${CROSS_COMPILE}-objcopy -O binary -R .note -R .comment -S vmlinux linux.bin
gzip -9 linux.bin
mv -f linux.bin.gz linux.bin
#需要修改 .its
mkimage -f fit-image-petalinux-user-image.its image.ub
编译 UBoot
取得UBoot源代码和配置后，需要有工具链的环境，编译：
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- clean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- xilinx_peta_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j 2
得到u-boot（实际上就是u-boot.elf）
打包 BOOT.BIN
1、需要4个文件：u-boot.elf、zynq_fsbl.elf、bootgen.bif、system.bit。
u-boot.elf：就是uboot编译生成的bootgen.bif：可以自己手写。zynq_fsbl.elf：Vivado创建PS以后，在SDK中创建File-New-Application Project-Zynq FSBL以后Build Project生成的。system.bit：FPGA工程师生成的二进制流，用于PL端烧写的（可以没有）
2、修改bif文件，或者自己搞一个。
#cat build/bootgen.bif
//arch = zynq; split = false; format = BIN
the_ROM_image:
{
[bootloader] /tmp/tmp.SXFL3UZOJ7/zynq_fsbl.elf
/tmp/tmp.SXFL3UZOJ7/system.bit
/tmp/tmp.SXFL3UZOJ7/u-boot.elf
}
3、使用下列命令创建BOOT.BIN。
bootgen -arch zynq -image bootgen.bif -o BOOT.BIN -w on
$ bootgen -help

}
patelinux-package 打包 BOOT.BIN
使用bootgen好像有问题，总是提示u-boot文件出现问题：
[ERROR] : Multiple executable program sections in /tmp/u-boot.elf
因此，还是推荐使用这个方法，但是这个方法需要在petalinux工程中进行。
petalinux-package --boot --fsbl ./images/linux/zynq_fsbl.elf --fpga ./images/linux/system.bit --u-boot --force && cp images/linux/BOOT.BIN /tftpboot/BOOT.BIN_for_emmc
编译uboot、Linux
编译uboot、kernel方法很常见，我这里介绍我自己使用的方法。
思路：先把通用的配置保存起来，编译uboot、kernel的时候只需要读取配置就可以了
配置

kernel
与uboot类似，配置项有一些小差异而已。
