To guide customers through the board bring-up process after shipment.
This document provides a step-by-step guide for bringing up the DA14531 SmartBond Tiny Module Development Kit. It includes power-up procedures, debugging configurations, and initial testing to ensure proper functionality.
- DA14531 SmartBond Tiny Module Daughterboard (DB)
- DA145xx DEVKT-P PRO-MB
- USB Cable (Type-B)
- Coin Cell Battery (CR2032) (Optional)
- JTAG Debugger (Optional)
- MikroBUS™ Module (Optional)
- The DA14531 SmartBond Tiny Module DB supports:
- UART and JTAG connectivity
- MikroBUS™ module integration
- General-purpose buttons and LEDs
- Multiple power options (VLDO, Coin Cell, USB)
- Stand-alone operation
4.1 Default Power Supply Configuration
By default, the board is powered via the VLDO of DA145xx DEVKT-P PRO-MB.
Steps:
- Connect the DA14531 DB to the DA145xx DEVKT-P PRO-MB.
- Ensure jumper J5 is set to 1-3 for 3.0V operation.
- Remove J1 jumpers (1-2, 3-4, 5-6, 7-8, 9-10) to disable SPI flash.
- Insert the USB cable into DA145xx DEVKT-P PRO-MB and power it on.
4.2 Coin Cell Battery Power Option
- Insert a CR2032 coin cell battery into the holder on the bottom side.
- Ensure that power is NOT being supplied from DA145xx DEVKT-P PRO-MB.
- Switch the power selector to Coin Cell mode.
4.3 USB Power Supply
- Populate R42 to enable USB power.
- Connect a USB cable to the J6 mini USB connector.
- Ensure SW4 is configured for USB power mode.
5.1 JTAG Configuration
Connect a JTAG debugger to J2 on the DA14531 DB.
Ensure the following jumper settings on DA145xx DEVKT-P PRO-MB:
J1: 21-22 (SWCLK), 23-24 (SWDIO)
J1: 25-26 (RESET)
5.2 UART Configuration
Choose one of the following UART configurations:
Single-Wire UART
- P0_5: RxTx
- J1: 19-20 (Enable single UART)
Two-Wire UART
- P0_6: Tx, P0_5: Rx
- J1: 15-16, 17-18
Four-Wire UART
- P0_6: Tx, P0_5: Rx, P0_7: RTS, P0_8: CTS
- J1: 11-12, 13-14, 15-16, 17-18
6.1 Power-On Test
- Power the board using one of the methods described in Section 4.
- Verify that the LED D2 turns on (indicating power is supplied).
- Press SW2 to test the general-purpose button functionality.
6.2 Connectivity Test
- Connect the board via USB and open a serial terminal.
- Set baud rate to 115200 bps.
- Send test commands over UART to check responses.
- Verify that JTAG is detected using the debugging tool.
