配置
Start the menuconfig for the system-level configuration:
开始 系统级别的 menuconfig：
$ petalinux-config
Parse the configuration onto Kconfig without opening the GUI（--oldconfig）, for the root filesystem（-c rootfs）:
无GUI配置组件。
# 以根文件系统为例
petalinux-config -c rootfs --oldconfig
Load the Linux kernel configuration with a specific default configuration:
以指定的配置文件对组件进行配置：
注意，这样的配置文件需要存在于kernel或者uboot的源码树中，不能额外指定外部文件。
否则会报错：ERROR: linux-xlnx-4.14-xilinx-v2018.3+gitAUTOINC+eeab73d120-r0 do_kernel_metadata: A KBUILD_DEFCONFIG 'xxx' was specified, but not present in the source tree
# 以内核为例
petalinux-config -c kernel --defconfig xilinx_zynq_base_trd_defconfig
# 以 uboot 为例
petalinux-config -c u-boot --defconfig xilinx_zynqmp_zcu102_defconfig
Generate the source code for fsbl/fs-boot:
生成源码（以fsbl/fs-boot为例）。
petalinux-config -c bootloader
构建
Build the entire PetaLinux project
构建整个PetaLinux工程
petalinux-build
Build the kernel forcefully
强制构建内核
petalinux-build -c kernel -f
Compile a kernel forcefully
强制编译内核
petalinux-build -c kernel -x compile -f
Clean all build collaterals from the U-Boot component of the PetaLinux project.
清理构建中间组件
$ petalinux-build -c u-boot -x cleansstate
Create an updated FIT image from the current contents of the deploy area.
从部署域的当前内容创建更新的FIT映像。
petalinux-build -x package
清理
Clean all build collaterals. It removes build/, ${TMPDIR} and images. This will bring the
project to its initial state
## 慎用
petalinux-build -x mrproper
Clear the build area of the PetaLinux project for archiving as a BSP or for revision
control. This example retains the images directory of the project
petalinux-build -x distclean
