While checking the BCC_S32K144_Monitoring example, a red LED is displayed and an error occurs

Hi I am testing FRDM33772BSPIEVB and S32K144EVB-Q100. While checking the BCC_S32K144_Monitoring example, a red LED is displayed and an error occurs. The battery pack is not connected. Is there a way to check the code normally without the battery pack?

Hi Jang,

The connection of a battery pack is not strictly required for getting the mentioned example working. However, the battery pack connector is used also for supplying the MC33772B device itself. Therefore, you should use at least pins X1-2 (POS_BATT) and X1-34 (NEG_BATT) of the battery pack connector to supply the device, e.g. by 12V.

Best regards,

Tomas
