UART issue if i selected the FULL clock frequency

[RAMASUBBU]

Hi all,

I am working with NUCLEO-412G board.In this i have replaced the chip with STM32F407 .
My issue with UART it was working fine when i select the frequency 8 MHZ as its osc pin.if i switched to the full speed of the controller 168 MHZ it was not working

I would like know if any configuration i have to do for this .in the attachment you can find my project setting screen shots ..



Note:
The clock input is come from the ST_link mc_out . not from the crystals

Regards & Thanks,

Hi dusan,

In your attachment MCU clock frequency is 8.00 mhz

But in my case i need 168 MHZ

Hi,

The clock configuration is for 168MHz.
The number does not changed when you load the scheme so it needs to be changed manually.
