Getting Started

Prerequisites

All of the following prerequisites must be available in your PATH.

  • CMake
  • RISC-V GNU Toolchain (Newlib) with support for rv32im.
  • vegadude. Grab the latest release here. This is the uploader tool to upload your program to your Aries development board. It let's you upload your program directly from cmake via cmake --install without having to use a 3rd party terminal.
  • Ninja : For Windows Only. Linux systems do not require this.

Terminal emulator

For terminal, minicom is recommended on Linux. Taurus creates a minicom configuration for aries boards by default for ease of use, which you can access by simply running sudo minicom aries.

You can also choose to use a different terminal emulator.

CDAC Aries boards use the following configuration:

Property Value
Parity No
Stop bits 1
RTS/CTS 0
Bits 8
Baud rate 115200

Steps

setup.bat --target-triplet <Target Triplet> --target-board <Target Board>

Run the commmand prompt as Administrator if you want to install Taurus SDK in the default directory (C:\Program Files (x86)\taurus). You can use --install-path <path> to specify where you would like to install.

  • On Linux, run:
./setup.sh --target-triplet <Target Triplet> --target-board <Target Board>
  • <Target Triplet>: Target triplet from the RISC-V GNU Toolchain. If you are using a prebuilt toolchain, go to your toolchain directory, there will be a folder with the format riscv64-<vendor>-elf. For example, riscv64-unknown-elf.
  • <Target Board>: This is the board you are using. Available options are: ARIES_V2, ARIES_V3, ARIES_MICRO_V1, ARIES_IOT_V1.
  • If you are using a different board, you can also use the option --target-soc and specify the SoC name. Available options are: THEJAS32, THEJAS64 and CDACFPGA.
  • The setup script offers a lot of fine tunable options. you can run the script --help for detailed usage.

Finishing Up

After running the script, you will be greeted with a success message. If you are using Linux, it will also create a minicom configuration for ease of use. You can skip this by running the setup script with --no-minicom

If you are getting errors, please create a GitHub issue.

Otherwise, you can proceed to create project using Taurus, or compiling and uploading examples.
