VSRVES01 CAT Board

• Supports VSRVES01 devices
• Support for compiling and modifying Linux will be added before end of Q2/2025 (see section Resources below)
• Support for compiling and modifying Real-Time VSOS will be added before end of Q3/2025

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.

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.
