original intention
The Petalinux2021.2 tool is relatively new, and it is difficult to find a solution to the problems used in the process of use on the Internet, resulting in a problem being stuck for several days, or even directly from getting started to giving up. I hope that sharing the problems I have encountered can bring little value to the majority of colleagues.

problem causes
In the Petalinux2021.2 download address, the bottom "PetaLinux Tools sstate-cache Artifacts" states that sstate-cache is only needed when using Petalinux offline. However, due to the instability of the domestic network, during the compilation process of Petalinux, there may be a problem that the download of sstate-cache fails, which leads to the above error.
Solution
1. Download aarch64 sstate-cashe
2. Unzip the downloaded file in any directory
3. Run
petalinux-config
The configuration location is:
-> Yocto Settings->Local sstate feeds settings->local sstate feeds url
4. Enter the above decompression path into it
/<解压路径>/aarch64
5. Exit with an error, recompile the petalinux project, and the error disappears

petalinux-config --get-hw-descriptionI get the following error when using the command

Check the cause of the error through the vim ./build/config.log command.
Enter in the terminal and sudo apt-get install libtinfo5re-execute after installation.
