Populate jumper JP6. Connect SPI9 pins to SPI3 pins:

INSTANCE0(SPI9)     CONNECTS TO         INSTANCE1(SPI3)
Pin Name   Board Location     Pin Name  Board Location
SCK        J9 pin 9           SCK       J14   pin 4
MISO       J9 pin 11          MISO      J9    pin 20
MOSI       J9 pin 13          MOSI      J12   pin 12
PCS0       J9 pin 15          PCS0      J14   pin 1

Prepare the Demo

Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J8) on the board
Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
Download the program to the target board.
Pull the micro USB cable out of the LPC-Link USB port (J8) and plug it into the port (J1) on the board.
Connect Dupont Lines between USB to UART interface module and the port (P4) on the board, and connect USB to UART interface module to the PC.
Reset the SoC and run the project.

Running the demo

This demo is an external flash plain load demo, ROM will copy image in external flash to SRAMX to run:

Build the demo to generate a bin file. Note: If need to generate bin file using MCUXpresso IDE, below steps need to be followed: Set in example Properties->C/C++ Build->Settings->Build steps->Post-build steps->Edit enbable arm-none-eabi-objcopy -v -O binary “&{BuildArtifactFileName}” “&{BuildArtifactFileBaseName}.bin”
```
  This plainload example linked the vector table to 0x00000000, but program to external flash 0x10000000.
```
Program the bin file to external on board flash via SEGGER J-FLASH Lite(V6.22 or higher):

a. Open SEGGER J-FLASH Lite, select device LPC54S018M.

b. Click the ‘Erase Chip’ to erase the extrenal flash.(if can not success, press SW4 button and reset the board, and try to erase again)

c. Select the bin data file, set the ‘.bin/Erase Start’ address to 0x10000000, then click ‘Program Device’ Note: Please use above way to program the binary file built by armgcc tool chain to external flash. For IAR, KEIL, MCUXpresso IDE, you can use the IDE tool to program the external flash.
When the demo runs successfully, the log would be seen on the CMSIS DAP terminal like:

FreeRTOS SPI example start.
This example use one SPI instance as master and another as slave on one board.
Master and slave are both use interrupt way.
Please make sure you make the correct line connection. Basically, the connection is: 
 SPI_master -- SPI_slave   
   SCK      --    SCK  
   PCS0     --    PCS0 
   SOUT     --    SIN  
   SIN      --    SOUT
