Looks like for some reason Petalinux 2019.2 doesn’t add it’s compilers to the PATH when sourcing the settings script. You can add it manually - they’re at `{}/tools/xsct/gnu/microblaze/lin/bin/`. Note that we don’t support 2019.2 so can’t help you with any other Petalinux issues that arise. Also I’d strongly recommend the [board agnostic flow](https://discuss.pynq.io/t/quick-porting-of-pynq-using-pre-built-images/1075) and avoiding the issue entirely.
