Description

VSRVES01 CAT Board is an evaluation board to test the most commonly used capabilities of the VSRVES01 integrated circuit.

VSRVES01 is a hybrid SoC, capable of running simultaneously Linux on an RV32IM RISC-V core, as well as VLSI Solution's Real-Time VSOS on a proprietary VSDSP6 core.

The CAT Board allows testing both of these features: it has connections for Ethernet, SD Card, Line Audio In, Line Audio Out, and it includes LPDDR2, SPI Flash, a couple of buttons and, or course, two programmable cat's eyes. It is a chance to get your feet wet with VLSI Solution's new RISC-V32 product line.

Documentation to make it possible for customers to build their own versions of Linux and VSOS applications is being made available on a continuous basis.

Resources

Below is a list of various free and open resources available now or soon from VLSI Solution. They will be updated regulardly as new information becomes available. Our goal is to in time provide all information needed for our customers to compile and if necessary modify their own Linux kernels and applications.

Documentation:

  • VSRV Datasheet - An extremely work-in-progress version at the moment
  • VSRV User's Guide - What the VSRV chip and VSRVES01 Cat Board are, how to use them, and how to compile your own Linux toolchain and kernel for it
  • VSRV VSOS Shell - How to use the VSDSP VSOS Shell
  • VSRV VSOS Audio - Introduction to the VSDSP VSOS audio subsystem

Software:

  • VSOS Root Image - Latest version of the files for the VSRVES01 Cat Board's microSD card (including both VSDSP/VSOS and RISC-V/Linux)
  • Linux ethernet driver - Source code for the Ethernet driver required by VSRV1 (Note:. All other hardware features work wihtout a custom driver)
  • elf2vri - Linux C source code for program needed to convert Linux ELF and binary files to the VRI format required by CAT Board's DDRLoad
