Dear Sir,
We are currently developing a custom RF project using the STM32H747XIH6 microcontroller. In our design, we have successfully tested the Cortex-M7 core by executing various test programs, including LED blinking and ADC integration. However, we are facing a critical issue with the Cortex-M4 core.
When attempting to load a simple LED blinking program onto the M4 core, the debugger enters an unknown state, and the code does not execute. We have verified the hardware and power supply rails, and the M7 core continues to function correctly under the same setup.
We would like to understand if this issue could be related to hardware initialization, boot configuration, or if there are specific prerequisites for the M4 core to operate independently. Your guidance or any recommended debug procedures would be highly appreciated
Best regards,
Samudralankaiah.
