open-isa is a non-profit RISC-V Community for all open-source ISA enthusiasts. It's built by open-source enthusiasts in software R&D and system/applications Engineers. Its purpose is to expand and drive the RISC-V ecosystem and industry-wide adoption. With open-isa community, global developers can share their ideas and experiences. The projects supported by open-isa are open to all relevant ecosystem partners. The boards built by open-isa are available for free in promotion stage. One of the first project on open-isa is VEGAboard, a development board with two RISC-V cores and Arduino compatible pin headers. open-isa has many ecosystem partners such as Ashling Microsystems, Express Logic, Foundries.IO, IAR system, Segger and Alibaba, RT-Thread who had adopted VEGAboard to support RISC-V ecosystem. Welcome to open-isa world and work together for RISC-V ecosystem.
