What is value od HSE on nucleo L432KC?

[oeliks]

Hi, what is the value of HSE on nucleo nano board stm32l432kc ?

​

​

Future : 24MHz crystall

​

But when I initialize default settings in cubemx it sets HSE as 8 MHz.​

​

Cant find value of HSE on board in board User Manual.​

There is no HSE crystal mounted on Nucleo-32, and also there's no OSC_OUT pin on the 'L432KC, so you cannot use a crystal for HSE with that chip.

It still has OSC_IN, so you can use an external oscillator and HSE in Bypass mode. On the Nucleo-32, you would need to connect SB17 which connects the MCO output from the on-board STLink chip ('F103) to PA0 of the target i.e. 'L432KC, and the STLink's MCO output is 8MHz.
