Overview

The TLSR9518A Generic Starter Kit is a hardware platform which can be used to verify the Telink TLSR951x series chipset_ and develop applications for several 2.4 GHz air interface standards including Bluetooth 5.2 (Basic data rate, Enhanced data rate, LE, Indoor positioning and BLE Mesh), Zigbee 3.0, Homekit, 6LoWPAN, Thread and 2.4 Ghz proprietary.

More information about the board can be found at the Telink B91 Generic Starter Kit Hardware Guide_ website.

Hardware

The TLSR9518A SoC integrates a powerful 32-bit RISC-V MCU, DSP, AI Engine, 2.4 GHz ISM Radio, 256 KB SRAM (128 KB of Data Local Memory and 128 KB of Instruction Local Memory), external Flash memory, stereo audio codec, 14 bit AUX ADC, analog and digital Microphone input, PWM, flexible IO interfaces, and other peripheral blocks required for advanced IoT, hearable, and wearable devices.

The TLSR9518ADK80D default board configuration provides the following hardware components:

  • RF conducted antenna
  • 1 MB External Flash memory with reset button
  • Chip reset button
  • Mini USB interface
  • 4-wire JTAG
  • 4 LEDs, Key matrix up to 4 keys
  • 2 line-in function (Dual Analog microphone supported when switching jumper from microphone path)
  • Dual Digital microphone
  • Stereo line-out

Supported Features

.. zephyr:board-supported-hw::

.. note:: To support "button" example project PC3-KEY3 (J20-19, J20-20) jumper needs to be removed and KEY3 (J20-19) should be connected to VDD3_DCDC (J51-13) externally.

For the rest example projects use the default jumpers configuration.

Limitations

  • Maximum 3 GPIO pins could be configured to generate interrupts simultaneously. All pins must be related to different ports and use different IRQ numbers.
  • DMA mode is not supported by I2C, SPI and Serial Port.
  • UART hardware flow control is not implemented.
  • SPI Slave mode is not implemented.
  • I2C Slave mode is not implemented.

Default configuration and IOs

System Clock

The TLSR9518ADK80D board is configured to use the 24 MHz external crystal oscillator with the on-chip PLL/DIV generating the 48 MHz system clock. The following values also could be assigned to the system clock in the board DTS file :zephyr_file:boards/telink/tlsr9518adk80d/tlsr9518adk80d.dts:

  • 16000000
  • 24000000
  • 32000000
  • 48000000
  • 64000000
  • 96000000

.. code-block::

&cpu0 { clock-frequency = <48000000>; };

PINs Configuration

The TLSR9518A SoC has five GPIO controllers (PORT_A to PORT_E), but only two are currently enabled (PORT_B for LEDs control and PORT_C for buttons) in the board DTS file:

  • LED0 (blue): PB4, LED1 (green): PB5, LED2 (white): PB6, LED3 (red): PB7
  • Key Matrix SW0: PC2_PC3, SW1: PC2_PC1, SW2: PC0_PC3, SW3: PC0_PC1

Peripheral's pins on the SoC are mapped to the following GPIO pins in the :zephyr_file:boards/telink/tlsr9518adk80d/tlsr9518adk80d.dts file:

  • UART0 TX: PB2, RX: PB3
  • UART1 TX: PC6, RX: PC7
  • PWM Channel 0: PB4
  • PSPI CS0: PC4, CLK: PC5, MISO: PC6, MOSI: PC7
  • HSPI CS0: PA1, CLK: PA2, MISO: PA3, MOSI: PA4
  • I2C SCL: PE1, SDA: PE3

Serial Port

The TLSR9518A SoC has 2 UARTs. The Zephyr console output is assigned to UART0. The default settings are 115200 8N1.

Programming and debugging

Building

.. important::

These instructions assume you've set up a development environment as described in the :ref:getting_started.

To build applications using the default RISC-V toolchain from Zephyr SDK, just run the west build command. Here is an example for the "hello_world" application.

.. code-block:: console

From the root of the zephyr repository

west build -b tlsr9518adk80d samples/hello_world

To use Telink RISC-V Linux Toolchain_, ZEPHYR_TOOLCHAIN_VARIANT and CROSS_COMPILE variables need to be set. In addition CONFIG_FPU=y must be selected in :zephyr_file:boards/telink/tlsr9518adk80d/tlsr9518adk80d_defconfig file since this toolchain is compatible only with the float point unit usage.

.. code-block:: console

Set Zephyr toolchain variant to cross-compile

export ZEPHYR_TOOLCHAIN_VARIANT=cross-compile

Specify the Telink RISC-V Toolchain location

export CROSS_COMPILE=~/toolchains/nds32le-elf-mculib-v5f/bin/riscv32-elf-

From the root of the zephyr repository

west build -b tlsr9518adk80d samples/hello_world

Telink RISC-V Linux Toolchain_ is available on the Burning and Debugging Tools for TLSR9 Series in Linux_ page.

Open a serial terminal with the following settings:

  • Speed: 115200
  • Data: 8 bits
  • Parity: None
  • Stop bits: 1

Flash the board, reset and observe the following messages on the selected serial port:

.. code-block:: console

*** Booting Zephyr OS version 2.5.0 *** Hello World! tlsr9518adk80d

Flashing

To flash the TLSR9518ADK80D board see the sources below:

  • Burning and Debugging Tools for all Series_
  • Burning and Debugging Tools for TLSR9 Series_
  • Burning and Debugging Tools for TLSR9 Series in Linux_

It is also possible to use the west flash command, but additional steps are required to set it up:

  • Download Telink RISC-V Linux Toolchain_. The toolchain contains tools for the board flashing as well.
  • Since the ICEman tool is created for the 32-bit OS version it is necessary to install additional packages in case of the 64-bit OS version.

.. code-block:: console

sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install -y libc6:i386 libncurses5:i386 libstdc++6:i386

  • Run the "ICEman.sh" script.

.. code-block:: console

From the root of the {path to the Telink RISC-V Linux Toolchain}/ice repository

sudo ./ICEman.sh

  • Now you should be able to run the west flash command with the toolchain path specified (TELINK_TOOLCHAIN_PATH).

.. code-block:: console

west flash --telink-tools-path=$TELINK_TOOLCHAIN_PATH

  • You can also run the west flash command without toolchain path specification if add SPI_burn and ICEman to PATH.

.. code-block:: console

export PATH=$TELINK_TOOLCHAIN_PATH/flash/bin:"$PATH"
export PATH=$TELINK_TOOLCHAIN_PATH/ice:"$PATH"

Debugging

This port supports UART debug and OpenOCD+GDB. The west debug command also supported. You may run it in a simple way, like:

.. code-block:: console

west debug

Or with additional arguments, like:

.. code-block:: console

west debug --gdb-port=<port_number> --gdb-ex=<additional_ex_arguments>

Example:

.. code-block:: console

west debug --gdb-port=1111 --gdb-ex="-ex monitor reset halt -ex b main -ex continue"
