Wrong value for RCC_CFGR_SWS_LSE

NPaqu.1 · ‎2025-07-08

Hello,

A set of new constants have been added to stm32g070xx.h by CubeMX v6.15.0, and one of them has the wrong value (at line 4200):

#define RCC_CFGR_SWS_LSE (0x00000100UL) /*!< LSE used as system clock */

According to the datasheet, the right value for LSE is 0x00000020UL.

Thanks.

Hello @NPaqu.1

Thank you for bringing this to my attention.

I will check it internally and get back to you ASAP.

Could you please add your IOC to reproduce the issue?

Used to be correct:

Then it got deleted entirely.

Then it got "fixed" but with the wrong value.
