This is the documentation for the latest (main) development branch of mcuxpresso sdk. If you are looking for the documentation of previous releases, use the drop-down menu on the left and select the desired version.

Hardware requirements

Micro USB cable
LPCXpresso54S018 board
Personal Computer

Board settings

No special settings are required.

Prepare the Demo

Connect a micro USB cable between the host PC and the LPC-Link USB port (J8) on the target board.
Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
Download the program to the target board.
Launch the debugger in your IDE to begin running the demo.

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 LPC54S018.

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) Note: if can not success( press SW4 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.
The log below shows the output of the hello world demo in the terminal window:
