UJA116xA evaluation boards
6 FlexGUI: interactive register control via USB
This section only applies to evaluation boards that feature an SBC with SPI interface:
• UJA1164A-EVB
•
UJA1168AF-EVB
• UJA1168AXF-EVB
When the UJA116xA-EVB is plugged onto a suitable microcontroller evaluation
board, the microcontroller board can be used as a USB/SPI interface between the
UJA116xA-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 UJA116xA-EVB currently supports the following evaluation board:
• S32K144EVB, Rev. B ( Figure 20 )
See www.nxp.com for more information about this board.

6.1 FlexGUI software package overview
The FlexGUI SW package for the UJA116xA-EVB can be downloaded from
www.nxp.com . It includes:
• the flexGUI PC installer (see also Section 6.3 )
• FlexGUI firmware for all supported microcontroller boards (see also Section 6.2.1 )
6.2 Preparations for using the S32K144EVB as a USB interface
The FlexGUI firmware must be loaded into the S32K144EVB before connecting the
UJA116xA-EVB. Note that the jumper settings for firmware programming are different to
those for FlexGUI usage.
6.2.1 FlexGUI firmware installation on S32K144EVB
Firmware programming in the S32K144EVB is straightforward:
1. Confirm that the jumpers are in the correct position for firmware programming
( Figure 21 )
2. Connect the board to the PC with a USB cable ( Figure 22 )
