Hello, As far as I understand and as explained [here](https://community.platformio.org/t/forked-mbed-os-and-platformio/2587/11), doing the following won't work: ```ini platform_packages = ; Custom mbed framework-mbed @ https://my/custom/mbed-os.git ``` Can you explain with some details how it is then possible to work with a custom fork of mbed?
