Hi guys, so far it's only an experiment, but I've started porting RIOT OS to the icoBoard Lattice FPGA / icoSoC / picorv32 RISC-V softcore CPU platform.
The Lattice chip used on the icoBoard is probably the only FPGA device supported by open source tools. And it will be the first FPGA device supported by RIOT OS (AFAIK) RIOT OS already supports the HiFive E310 RISC-V MCU, but that is a very different piece of hardware with RISC-V Privileged Architecture support. Still I've been able to reuse some code chunks. So far It's only an experiment (and I'm a newbie at this!), but all the important features already work, including shell over UART. It is really fascinating to be able to use a tiny FPGA board this way. If you are interested, you can find the (alpha, experimental!) code at: https://github.com/tstyblo/RIOT-icoboard It would make no sense trying to merge it into the mainline now, as the code needs a lot of testing, comments and improvements. But I'd like to use this opportunity to invite anyone interested in FPGA devices or in the RISC-V platform to check it out. Regards, -- Tomas Styblo tsty...@gmail.com
