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.
Other hardware features and example projects are not supported yet.
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
(``boards/riscv/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
``boards/riscv/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 `Zephyr Getting Started Guide`_.
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 ``boards/riscv/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
=========
Supporting UART debug and OpenOCD+GDB.
