Value of external high-speed clock (HSE). This symbol could be optionally
configured using device tree by setting "clock-frequency" value of clk_hse
node. For instance:
&clk_hse{
status = "okay";
clock-frequency = <DT_FREQ_M(25)>;
};
Note: Device tree configuration is overridden when current symbol is set:
CONFIG_CLOCK_STM32_HSE_CLOCK=32000000

Direct dependencies¶

CLOCK_CONTROL_STM32_CUBE && CLOCK_CONTROL

(Includes any dependencies from ifs and menus.)

Defaults¶

“0” if n
8000000
