    • J-Link STM32H7 connect to unbooted core

      Hi,

      I am using an STM32H747 chip.

      I have changed the default option bytes so the M4 core does not boot automatically. This means I can no longer connect to the M4 core, until the M7 has booted it.

      Using an STLinkV3 debugger, I am able to program the M4 in this configuration, without the M7 enabling it.

      What do I need to do to get my JLink to connect and program?

      Thanks
