Did you check Configurable Fault Status Registers (CFSR) - 0xE000ED28? You should first check the registries to see a summary of the fault for better troubleshooting. If no, try UsageFault Status Register (UFSR) - 0xE000ED2A. If you want I can help you in a week after I return to my property in Larnaca
