diode.
The 3.3 V or 5 V output from the SBC is routed to the microcontroller board via jumper
J7, where it supplies the main MCU.
The SPI signals are routed directly between the SBC and the main MCU via header J4
and its counterpart J2.
The RSTN signal on the SBC is connected to the reset input on the main MCU. When
terminals 2 and 3 of header J104 are connected with a jumper, pushbutton SW5 on the
MCU board allows the RSTN signal to be pulled LOW manually. This function could be
used, for example, when restoring the MTPNV register factory preset values.
The USB MCU is powered via the USB interface. The signals between main MCU and
USB MCU are passed through level shifters that serve as a bridge between the two
supply domains.
Double-click on file NXP_UJA1169Ax_GUI-1.0.0.msi to begin the installation.
FlexGUI can be started via the Windows Start menu or the shortcut symbol on the
