I 'm using STM32H747I-DISCO, with IAR toolchain. I tried some example in STM32Cube_FW_H7_V1.4.0, CM7 and CM4 are in two different configuration of a project(ex, STM32H747I_DIACOVERY_CM4 and STM32H747I_DIACOVERY_CM7), which can only be activated and ...

CAS==2 works when running @100MHz FMC. It's my mistake that I keep forgetting that I need to change both places since it uses two different macros.- https://github.com/STMicroelectronics/stm32h747i-disco-bsp/blob/bb81c6532fcc301fc760a98f8a42acede46b...
