Greetings backers! With the crowdfunding portion of the campaign over, it's time for us to work on the Fomu firmware. We're using EVT boards for development, and the final revision of the EVT hardware just came in.
If you backed the "Fomu EVT Board" tier, you'll be receiving your very own EVT hardware. You can use this to follow along with the development of firmware, or do your own thing and develop something entirely different.
Since we don't yet have Fomu firmware, you can't use them as USB devices yet. However, we have basic demos working for communicating with the FPGA, and thanks to the Raspberry Pi these Fomu boards can't be bricked.
The Fomu EVT3 hardware has a URL printed on the front in silkscreen: tomu.im/fomu-evt3/. This contains information on how to get started. The overall approach to getting started is:
fomuand a password of
git clone https://github.com/im-tomu/fomu-tests/
cd fomu-tests/blink && make && fomu-flash -f blink.bin
We're working on examples of how to build a Risc-V CPU and communicate with it using the Raspberry Pi's serial port, and we're still working on solidifying the USB firmware that will eventually be loaded.
If you have questions or want to drop by to chat, we're on #tomu on Freenode. Stop by and say hello, or ask a question. Thanks for supporting us!
