How to enable a node in main.

Hi, enabling or disabling dts nodes during runtime is not possible.

The only references to the clk_lse node I could find in the SDK were in stm32_clock_control.h, which appears to rely on the node being enabled during boot in order to configure it correctly.

Hi Øivind

&clk_lse {
status = "disabled";
};

The code snap of disabling the LSE clock.

I need to enable it in main (basically I need to enable the node dynamically).

I need to disable in overlay to reduce the boot time of the device.

Hi,

Could you show me how you disable the node in the overlay? And in which file do you want to enable it?

If you can tell me why you need to disable it in the overlay and enable it somewhere else, that would also be helpful.
