2. Attach IMXMMINI-IARD connector plug J1 (located on the bottom of the board) into
J1003 expansion board located on the top side of i.MX 8M Mini LPDDR4 EVK (see
Figure 9 );
3. Powerup the EVK board using a USB-C cable attached to port 2;
4. Connect the EVK to the PC, using a USB Micro-B cable, attached to J901 debug
port;
5. Place SW101 in ON position to power up the boards;
6. Install the MIMXRT1050 target firmware (download UM11581, Arduino shields GUI
and firmware installation manual from NXP site);
7. Install GUI application on the PC (see the instruction file referred in the above step);
8. Open the GUI application to operate the device from the PC. For details regarding
GUI operation see Section 7 .

6.4 Using PCA9617ADP-ARD with another device
The PCA9617ADP-ARD daughterboard can be operated with another EVK board, which
has an Arduino port. There are two options to connect the board: using another EVK
equipped with an Arduino port, and an EVK without an Arduino port. In the first case,
firmware shall be developed according to PCA9617A specifications; to operate the board,
attach PCA9617ADP-ARD daughterboard to the EVK. In the second case, using the
Arduino connectors pin chart ( Table 1 ), make the necessary electrical connections (for
power, I
2
C-bus and control lines), and develop the desired firmware, assuring that it is
compliant with IC specifications. Refer to PCA9617A datasheet to read details about
internal registers of the DUT IC and data exchange between internal controller and the
EVK. Check for correct electrical connections and avoid data conflicts on the signal lines,
to prevent IC damage.
