QSPI Flash Example


The QSPI Flash Example demonstrates the use of the QSPI peripheral with the memory mounted on nRF52840 M.2 Module.

The application initializes the QSPI peripheral, sends configuration commands to memory, erases the memory, writes data, reads data, and compares data.


Before you start building, remember to set up the nRF5 SDK development environment first. See Setup the nRF5 SDK for details.

Building the example

You can find the source code and the project file of the example in the following folder: examples/nrf5-sdk/qspi.

Open terminal and navigate to the directory with the example Makefile:

cd ./examples/nrf5-sdk/qspi/armgcc

Run make to build the example:


Programming the firmware

If compiled successfully, the firmware is located in qspi/armgcc/_build with the name nrf52840_xxaa.hex.

Connect the debugger USB port to your PC using the provided USB-C Cable. A disk drive called M2-DOCK will be automatically detected by the computer.

Run the following command in qspi/armgcc to program the board:

make flash_all


See Programming section for details about how to program the nRF52840 M.2 Module.


Test the QSPI Example application by performing the following steps:

  1. Run a terminal application like PuTTY or screen:

    screen /dev/cu.usbmodem14102 115200
  2. Press the RESET button, and observe the output of the terminal.
