I would like to know how to configure RCC on my evaluation Board STM32L552E-EV.

DYann.1 · ‎2023-03-03

I connect my I2C but when I connect an oscilloscope I have nothing on the clock signal. So probably I misconfigured my clock. Could you give me the information? Thanks in advance.

In this picture below I've a warning, do you know how to remove this warning please ?

Thank you for your helps.

Regards

Hello @DYann.1 ,

For the clock configuration, you can manager your clock with the tab "Clock Configuration"

You have to choose your Source:

for the HSE source, please follow this step :

If you select the MCU selector, you will have all peripherals without default mode.

Hope my answer helped you!

Hi,

Thank you for your helps, I have STM32L552E-EV evaluation Board and in your first screenshot I can't see the bottom of the screenshot, could you send me a complete copy of the screenshot please ? Why in the left of your picture all is green and for me I have the yellow color with exclamation marks, I'm afraid something is wrong that why I don't have the Clock of I2C. Normally it's automatic.

Thank you for your helps.

Thank you, I'll do the same configuration with my evaluation board and I hope I don't have any warning again.

Now with STM32cube i selected my evaluation board like this picture

I don't slected by default, because my configuration is probably not the same as default.

I don't have the possibilty to do the same as your configuration.

Do you also have the STM32L5 card? Or else it's not very important. And When I want to generate the code it shows me errors.

Do you know where this error comes from ?

DYann.1 · ‎2023-03-06

I have always the warning about RCC.

Something is wrong ?

I f you try with MCU selector and select the STM32L552ZE MCU:
