СС2650 fault without periodical clock

AntonNadezhdin

Hi TI,

I have some strange problem:

I do some changes in SimpleBLEPeripheral: add Sensor Controller tasks, add some process on the periodic clock. And it works good but if I disable the periodic clock the MSU will fault after about 100-150 ms after reset: the Bluetooth stop advertising and Sensor Controller stop process the GPIO. On the other hand, if I start the debugging session without any breakpoints, MCU is working normally. Is this problem related to low power modes?

Hello,

It's almost impossible to say what could be going on based on the description alone. Have you tried adding your changes 1x1 to see when the problem occurs? Does the problem go away if you disable PM?

Best wishes

Yes, the problem is going away if I disable the PM or disable the Sensor Controller. My sensor controller task generate Alert every 1 ms, may be CM3 in the sleep doesn`t correctly process this alert and this cause to Hard fault?
