Hi,

Does anyone know why I cannot change 0x3 to 0 of ST_RAM_SIZE at STM32H743?

Hi @TLung.1​ ,

It is normal behaviour, we cannot decrease the ST_RAM_SIZE .

I will request to mention this clearly in H7 refernce manual.

In the RM0399, Rev 4, June 2023 Reference Manual, it is still NOT clearly indicated that you can not decrease the ST_RAM_SIZE once it has been increased.
