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

Does this make sense?

Is it the sort of thing that Segger would look to fix or do I need to rely on the STLinkV3 to access an unbooted core?

Thanks
