Thank you for this advice.After discussing with the hardware designer, confirm that the PULL UP method need to be revise.Problem solved after the rework done to CEC line.

How to check HSE has stop

I am using STM32H723 for my project, I plan to create a scatter file for the mapping area but I couldn't found any Memory Mapping explanation on the provided data sheet or programming guide. Does anyone know where I can refer the memory Mapping
