The OpenEmbedded build system uses BitBake to generate the software development kit (SDK) installer script standard SDKs. PetaLinux builds Yocto SDK and installs it. The installed SDK can be used as a sysroot for the application development. Build the SDK with the following command:
petalinux-build -p build/vck190_petalinux –sdk
This command builds the SDK and copies it at build/vck190_petalinx/images/linux/sdk.sh.
