STM32H7 dual core debugging

What is ST's response to this document and the fact that I am witnessing such behaviour (see image) ?? Was there simply an error in this document? I was following the doc only to be frustrated by M4 hitting a brick wall with SIGTRAP, there is mention of "option bytes" by user TDK here. Is thee something that I am missing and I can edit these option bytes in either STM32cubeIDE or CUBEMX or is this strictly a CubeProgrammer ability? BOOT_CM4=0 in the option bytes??? Where is this?? Can I change this Via GUI interface?? Should I proceed and think nothing of it and consider this error in document?

Please clarify... Thank you.0693W000005Ag79QAC.jpg
