Experience issues to run to dual core stm32h757xih6
Hi, I’m beginner in this and where’s no a lot of manuals how to do that ,
but looks like I’m done everything but still experience some ”hangs” like after run every debug or run I can’t to anything it’s halt and that’s all

here’s my mcu

here’s the log what I get when I try to debug nor run , and I tried different ways to launch it but still I experience “halts” of mcu and strange issues with stm32 programmer (looks like it doesn’t see the mcu screenshot below )
