B92 Generic Starter Kit Hardware Guide

Contents

Introduction

The guide introduces how to get started with the Kit. B92 Generic Starter Kit is a hardware platform which can be used to verify TLSR952x series chipset and develop many kinds of 2.4G protocol application, including Bluetooth basic rate (BR), enhanced data rate (EDR), low energy (LE), Bluetooth LE Mesh, 2.4 GHz proprietary, RFFE and Wi-Fi Coexistence Interface.The TLSR952x combines the features and functions needed for high quality wearable devices into a single System-on-Chip (SoC).

Quick Start

Flash Programming

Developers can choose any of the following tools for flash programming.


TLSR9528A supports easy debug method. Only three wires are needed.

  • 3.3V from Telink Burning Board is connected to VBAT from TLSR9528ADK88D.
  • SWM from Telink Burning Board is connected to SWS form TLSR9528ADK88D.
  • GND from Telink Burning Board is connected to GND form TLSR9528ADK88D.

RF Test

Power on firstly, then connect RF SMA through cable to equipment or through whip antenna when verifying chipset or develop function. The corresponding tool is EMI tool which can be gotten from wiki.

Use the right bin and tool after checking the test instrument.

  • When using EMI tool and bin, user often use spectrum analyzer to do rf test.

  • When using BQB bin, user often use CMW500, MT8852B and so on to do rf test.

GPIO Test

  • All of GPIOs of TLSR9528A have been connected to PINs.
  • Then users can read the corresponding schematic and test all GPIOs.
  • If the B92 series chip has the CFG pin, then you can adjust the power domain of GPIO. if the CFG pin is connected to VDDO3, power domain of GPIO is 1.8V; if the CFG pin is connected to GND, power domain of GPIO is 3.3V. In addition, the TLSR9528A does not have the CFG pin, so it cannot adjust the power domain of the GPIO. The power domain of the TLSR9528A’s GPIO is 3.3V.
