I am working with stm32h745ZIT3, in my application I need to receive some packets over ethernet in CM7 and these packets need to share to CM4, and processing is done in CM4. So, to test this data transfer I need to debug both cores simultaneously. Tried changing the debug properties as download option disabled for cm4 and add cm4 to cm7s list. and then tried to debug cm7 and then debug cm4, but cm4 shows as no ST detected. Also, port number changed for both. Is there anything I am missing? please guide me.
