Hi
Yes, it is possible to override CLOCK_SOURCE.

Here is an example of mbed_app.json:

{
"target_overrides": {
"NUCLEO_F410RB": {
"target.clock_source": "USE_PLL_HSI"
}
}
}

I agree this is not so easy to use and understand... Maybe ARM should update MBED page:
https://docs.mbed.com/docs/mbed-os-handbook/en/5.2/advanced/config_system/

Have also a look on ST wiki page:
https://os.mbed.com/teams/ST/wiki/Automatic-clock-configuration

Thanks @jeromecoutant.

@iriark01 I see we don't have a section for target settings in https://os.mbed.com/docs/v5.6/reference/configuration-overview.html, would be good to add.

@janjongboom You can find the section about adding and configuring targets here: https://os.mbed.com/docs/v5.6/tools/adding-and-configuring-targets.html

@AnotherButler Nothing there mentions the ability to override target properties through mbed_app.
