Hello!
i am working with the stm32h745 nucleo 144 board.
i want to be able to debug both cores simultaneously using the onboard STLINK debugger, with no luck so far.
followed the instructions from this ST document: https://www.st.com/resource/en/application_note/dm00597308-stm32h7x5x7-dualcore-microcontroller-debugging-stmicroelectronics.pdf
the defenitions are in place, i am able to start download and debug on one of the cores (doesnt matter which) as long as the other one is not touched. as soon as i try to start debbugging the other one (on a seperate instance of IAR) i get the following error message: Fatal Error - STLINK connection error.
please advise on how to make this work and what am i doing wrong?
thanks in advance.

Hi, thanks for responding.
i have tried with the board as it arrived.
after i was unsuccessful i have connected to the nucleo board with stmCubeProgrammer
and updated the ST link to V3.
still doesn't work.
