6.4 Establishing the connection between the NXP GUI and the hardware
The device manager allows the connection of the PF5030 development board with the NXP GUI.
Before plugging the KL25Z USB port to the computer, the MCU is in a "NOT DETECTED" state.
After plugging in the USB, the MCU state changes to "DISCONNECTED." If the state does not change, press
the RST button on the freedom board.
At this state, the communication with the MCU can be started.
The MCU state changes to "CONNECTED" and the firmware version is displayed.
To start the communication with the PF5030, click the "Start" button. The GUI is able to identify the device
address to establish the communication.
When the communication has started successfully, the PF5030 (device name) switches to green.
When the device starts with the DBG pin voltage at 7.95 V (EVB OTP mode LED on), the state machine stops
at the Main/FS OTP MODE state.
The current mode can be read using the refresh button and loop refresh button highlighted in red. Clicking
refresh reads the state one time. Clicking the loop refresh latches and reads the state periodically until a new
click deactivates it.
