Hello,
we have produced 10 Boards with nRF9151. Unfortunately, 3 device shows a false behavior. We cannot connect over SWD an they have a larger power consumption (whole circuit) of 24mA instead of 5mA in case of the good one (measured without firmware).
Also nReset is permanently low without connection though other components in the circuit. VDD has 3.3V but error message says "Low voltage 0"
Component NRF9151 reacts to external heat and external cold temperature in form of other error messages.
Do you have an idea ?
