An Embedded RISC-V Blog

A blog about embedded development for the RISC-V ISA. General information on the RISC-V ISA.

Several years ago I was responsible for the bring up of deep embedded firmware application and RTOS on an in-house developed RISC-V core. As RISC-V is a new architecture, there was not much public information available to assist in the task. At that time I decided to put back the knowledge gained about RISC-V to the community.

The contents here are anything I’d like to reference during development. Things as a developer of RISC-V embedded software I find interesting. The initial focus is on low level/bare metal development.


What is RISC-V

RISC-V is a free and open ISA enabling a new era of processor innovation through open standard collaboration.


For embedded development RISC-V is now an alternative to ARM, although it won’t displace ARM anytime soon. It’s also an alternative to royalty free legacy cores, such as synthesizable 8051 cores, that remain in many deep embedded applications.
