Hello,

In case HSE firmware is loaded, FIRC will be fully controlled by HSE, and application has no right to configure FIRC. As a result, you need to select "FIRC under MCU control" as "Disabled":

Best Regards,

Hello @wuxianlong,

That part of code is added in RTD 2.0.0 for supporting customer who wants to modify the FIRC clock divider, and for sure the HSE firmware must not be installed.

Hello Nam,
thanks for your help. I tried it, and your answer was very helpful, but I'm a little confused.
As you said, the application does not have permission to configure FIRC. Why is this part of code added in RTD2.0.x , and I did not find it in RTD1.0.0?
