使用命令“petalinux-devtool modify”BSP相关的代码。
作者： 付汉杰 hankf@xilinx.com hankf@amd.com
测试环境： Vivado/PetaLinux 2021.2， Linux 5.10.0 VCK190
在PetaLinux 2020.1时分享了在PetaLinux里为模块创建补丁。
现在使用PetaLinux 2021.2， 发现类似命令会报告错误。

查询手册，得到命令“petalinux-devtool modify”，可以完成同样的工作。 对于VCK190单板，使用下列脚本，可以得到所有BSP相关的代码。
#
# Get the source code from git url specifi ed in meta-layers:
# petalinux-devtool modify <recipe-name>
#
# Creates a patch for the committed changes in recipe sources directory.
# petalinux-devtool finish <recipe-name> <destination layer path>
# $./yocto/layers/meta-xilinx/meta-xilinx-bsp/recipes-kernel/linux/linux-xlnx_2021.2.bb
echo -e "\nTry to modify linux-xlnx"
petalinux-devtool modify linux-xlnx
# ./yocto/layers/meta-xilinx/meta-xilinx-bsp/recipes-bsp/u-boot/u-boot-xlnx_2021.2.bb
echo -e "\nTry to modify u-boot-xlnx"
petalinux-devtool modify u-boot-xlnx
echo -e "\nTry to modify plm-firmware"
petalinux-devtool modify plm-firmware
echo -e "\nTry to modify psmfw"
petalinux-devtool modify psmfw
echo -e "\nTry to modify arm-trusted-firmware"
petalinux-devtool modify arm-trusted-firmware
echo -e "\nShow components that can be modified"
ls -l components/yocto/workspace/sources/
