### Build MCUboot from source
The following command will setup the mbed environment and clone the needed repositories before compile for Portenta H7.

```
mbed config root . && mbed deploy
mbed compile -m PORTENTA_H7_M7 -t GCC_ARM --profile=release --profile mbed-os/tools/profiles/extensions/lto.json
```
Additional flags are needed for [Lite](generate_rel.sh#L24) and [Lite Connected](generate_rel.sh#L35) boards.
