Hi everyone,
I've built a STM32H745ZIT6-based board. The microcontroller uses the LDO to generate VCORE. The idea of this board was to build a standalone solution based on my Nucleo-H745ZI-Q project.
I did prepare a very simple project, where I toggle a pin with a simple delay, to check that everything works, but sadly nothing seems to work. I'm trying both HSI and HSE clock source, but there is no difference.
The first strange thing that I noticed is that during debug the M4 core is stuck in hard fault, even if the configuration used is the same of my project based on the Nucleo:
Here is the debug window, and the fault analyzer output:
To understand if at least the CM7 works, I commented the "#define DUAL_CORE_BOOT_SYNC_SEQUENCE" to allow it to continue the execution. Nonetheless, the microcontroller seems completely unresponsive.
During debug it seems to go through "HAL_GPIO_TogglePin(CH8_GPIO_Port, CH8_Pin);", but the pin doesn't physically change state (it remains LOW). Furthermore, "HAL_Delay(500);" never returns (uwTick is always at 0);
I noticed that System tick timer NVIC1/2 has Preemption Priority of 15, but reducing it to 0 didn't change anything.
Did I do something wrong? Am I missing something or do I have a faulty unit?
