MDBT53V-DB-40

Overview

Raytac MDBT53V-DB-40 demo board is a development board based on the Raytac MDBT53V-1M module, using Nordic Semiconductor nRF5340 ARM Cortex-M33 SoC. Its design concept is to connect all of the module’s pins to 2.54mm pin headers. It is convenient for developers to verify whether the modules are connected to other peripheral devices or sensors as a tool for software development.

The nRF5340 inside the MDBT53V-1M module is a dual-core SoC based on the Arm® Cortex®-M33 architecture, with:

  • a full-featured Arm Cortex-M33F core with DSP instructions, FPU, and Armv8-M Security Extension, running at up to 128 MHz, referred to as the application core

  • a secondary Arm Cortex-M33 core, with a reduced feature set, running at a fixed 64 MHz, referred to as the network core.

The raytac_mdbt53v_db_40_nrf5340_cpuapp build target provides support for the application core on the nRF5340 SoC. The raytac_mdbt53v_db_40_nrf5340_cpuapp build target provides support for the network core on the nRF5340 SoC.

nRF5340 SoC provides support for the following devices:

  • ADC

  • CLOCK

  • FLASH

  • GPIO

  • IDAU

  • I2C

  • MPU

  • NVIC

  • PWM

  • RADIO (Bluetooth Low Energy and 802.15.4)

  • RTC

  • Segger RTT (RTT Console)

  • SPI

  • UARTE

  • WDT

Connections and IOs

LED

  • LED1 (green) = P0.31

Push buttons

  • BUTTON1 = SW1 = P1.13

  • BUTTON2 = SW2 = P0.25

  • BUTTON3 = SW3 = P0.26

HSPI

  • MOSI = P0.9

  • MISO = P0.10

  • SCK = P0.8

  • CSN = P0.11

  • DCX = P0.12

QSPI

  • SCK = P0.17

  • CSN = P0.18

  • DATA0 = P0.13

  • DATA1 = P0.14

  • DATA2 = P0.15

  • DATA3 = P0.16

Security components

  • Implementation Defined Attribution Unit (IDAU [1]) on the application core. The IDAU is implemented with the System Protection Unit and is used to define secure and non-secure memory maps. By default, all of the memory space (Flash, SRAM, and peripheral address space) is defined to be secure accessible only.

  • Secure boot.

Programming and Debugging

nRF5340 application core supports the Armv8-M Security Extension. Applications built for the raytac_mdbt53v_db_40_nrf5340_cpuapp board by default boot in the Secure state.

nRF5340 network core does not support the Armv8-M Security Extension. nRF5340 IDAU may configure bus accesses by the nRF5340 network core to have Secure attribute set; the latter allows to build and run Secure only applications on the nRF5340 SoC.

Applications for the raytac_mdbt53v_db_40_nrf5340 board configuration can be built, flashed, and debugged in the usual way. See Building an Application and Run an Application for more details on building and running.

Note

Flashing and Debugging Zephyr onto the raytac_mdbt53v_db_40_nrf5340 board requires an external J-Link programmer. The programmer is attached to the J1 or J9 SWD connector.

Flashing

Follow the instructions in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in Flashing. Then build and flash applications as usual (see Building an Application and Run an Application for more details).

Here is an example for the Hello World application.

Use a USB to TTL converter to connect the computer and raytac_mdbt53v_db_40_nrf5340 J13 connector pin 8(RX), 9(TX) and GND. Then run your favorite terminal program to listen for output.

$ minicom -D <tty_device> -b 115200

Replace <tty_device> with the port where the USB to TTL converter can be found. For example, under Linux, /dev/ttyUSB0.

Then build and flash the application in the usual way.

# From the root of the zephyr repository
west build -b raytac_mdbt53v_db_40_nrf5340 samples/hello_world
west flash

Debugging

The raytac_mdbt53v_db_40_nrf5340 board does not have an on-board-J-Link debug IC, however, instructions from the Nordic nRF5x Segger J-Link page also apply to this board. Use the Debug out connector of nRF52x DK to connect to the J1 connector, and use SEGGER J-Link OB IF to debug.
