After a couple of times that I reflashed the unit to debug, it became unresponsive. The first few times I got to download and debug the Sensor Demo project, the it stopped working alltogether. I got to connect the debugger and go step by step. In the file vl53l1_platform.c of the BLE_SensorDemo project, line 141, I noticed that the SystemClockTick is always 0 now. The interruption that causes the system tick to increment, SysTick_Handler, is never triggered. Obviously this is what prevents the firmware to work properly. What could cause this problem, especially considering that initially it was working as expected?
