Debugging startup won't progress past: bl SystemInit

Question

Firstly I'm very new to all of this so apologies if this is trivial.

I have been trying to debug and run a simple blinking led project onto a STM32WB nucleo board using the STM32CubeIDE v1.0 (MacOS). After staring the debugging session, the console displays download verified successfully yet I do not have the option to run the project only pause or terminate.

Using breakpoints it seems to be getting hung up at the line, bl SystemInit in the file startup_stm32wb55rgvx.s and never actually gets to the main function.

The project was created with the cubeMX inside the IDE. All firmware and software has been updated.

Im asking this here because I have had success with the Atollic TrueStudio IDE which makes me think this issue is IDE based?? Or do i just have change some settings?

Well indicative of some broken expectations in the function. You should stop the debugger and SEE where it is stuck, most likely the Error_Handler or HardFault_Handler.

Often dependencies on clock inputs, pll and flash wait state settings.

Check also compiler/linker command line settings passed by the tool chain, and as meta data in the project itself.
