We are using the QCA9377-3 on our board. It is failing to initialize when the temperature is below -10C. This part is rated for -40to85, correct?
The error we are seeing it that it writes to CCCR register 02 (I/O Enable). It then reads register 03 (I/O Ready), expecting a value of 02. But we are getting a value of 00.
Has anyone had a problem with this chip at cold? For a value of 02, what funciton is failing to initialize?
