Open Source RISC – Eclipse with RISC-V on the SiFive HiFive1 Board

Open Source software has been around for decades. But open source on hardware especially microcontroller is not much a reality these days. But there is something which might change this: RISC-V is a free and open RISC instruction set architecture and for me it has the potential to replace some of the proprietary architectures currently used. RISC-V is not new, but it gets more and more traction in Academia (no surprise).

I wanted to play with RISC-V for over a year, but finally a week ago I did one of these “hey, let’s buy that board” thing again. Sometimes these boards get on a pile to wait a few weeks or longer to get used, but that one I had to try out immediately :-).

Switching the Microcontroller Package, Device and Family

One of the major benefits of Processor Expert is that I can easily switch the device or processor used in a project. For example I can do my concept with a larger device with more FLASH and RAM, and then at the end easily switch to a smaller or even completely different device very quickly. For example I have a project working with the 64KByte FLASH version of the KE02Z (KE02Z68VLH2):
