User manual
When the UJA1169Ax-EVB is plugged onto a suitable microcontroller evaluation
board, the microcontroller board can be used as a USB/SPI interface between the
UJA1169Ax-EVB and a PC. After installing the FlexGUI application on a Windows PC
(see
Section
6.3), the contents of the SBC registers can be viewed and/or changed
interactively.
FlexGUI for UJA1169Ax-EVB currently supports the following evaluation board:
• S32K144EVB, Rev. B
See
www.nxp.com
for more information about this board.

The FlexGUI SW package for the UJA1169A evaluation boards can be downloaded from
www.nxp.com. It includes:
• the flexGUI PC installer (see also
• FlexGUI firmware for all supported microcontroller boards (see also
The FlexGUI firmware must be loaded into the S32K144EVB before connecting the
UJA1169Ax-EVB. Note that the jumper settings for firmware programming are different to
those for FlexGUI usage.
Firmware programming in the S32K144EVB is straightforward:
1. Confirm that the jumpers are in the correct position for firmware programming
(Figure
20)
2. Connect the board to the PC with a USB cable
3. Wait until the PC has launched new drive 'EVB-S32K144'
4. Copy the firmware file to that drive
