CASP Support For VEGA Series Microprocessor Development Boards
VEGA Microprocessors are a series of high performance microprocessors based on open source RISC-V instruction set architecture (ISA). These microprocessors are developed by C-DAC, India. This page describes how to get started with some of the VEGA Microprocessor development boards supported by CASP. It also includes examples and real world projects to help user to kick start their journey with these home grown processors. Currently Aries v3.0, Aries v2.0, Aries Micro v1.0 and Aries IoT v1.0 development boards are supported.
Getting Started
System Requirements
- Microprocessor development board with accessories such as USB cable etc.
- Desktop PC or Laptop with Windows 7 64-bit or above operating system installed
- USB drivers supporting the microprocessor board shall be installed on the Desktop PC or Laptop. Latest CP210X USB drivers for Aries IoT v1.0, Aries Micro v1.0, Aries v2.0, Aries v3.0 boards can be downloaded from OEM website. Alternatively, you may download from our website at this link.
Install CASP Software & Board Support Package
- Download and install latest version of CASP as described in this page – https://aadhuniklabs.com/casp-downloads
- Download and install required CASP Board Support Package (BSP) files for the VEGA Microprocessor boards from the above mentioned download page. More specifically, for VEGA Aries Series boards, user may download the two (.lib and .htc) BSP files from these links – https://aadhuniklabs.com/casp/bsp/lib/version_latest/casp_bsp_swadeshi.hlib and https://aadhuniklabs.com/casp/bsp/tc/version_latest/casp_bsp_riscv-none-elf-gcc.htc.
- Optionally, the tool chain (.htc) file https://aadhuniklabs.com/casp/bsp/tc/version_latest/casp_bsp_riscv64-vega-elf-gcc.htc may also be downloaded and installed as an alternative to above mentioned tool chain (.htc) file.
- Procedure to Install the BSP files is described in this video – https://aadhuniklabs.com/casp_res_videos/#casp_install.
Examples
Below examples are provided, targeting VEGA Aries v2.0 development board to enable novice users to start experimenting with these processors. User may also try experimenting with the CASP examples provided at this link with VEGA Microprocessor boards as target. This requires minor modifications with respect to pin configuration and other settings specific to the Vega Microprocessor target. Users are encouraged to go through our video tutorials and try to build the same (which ever applicable) on VEGA Microprocessor boards supported by CASP.
