RISC-V and 128MB memory

Do you think this board/FPGA could fit a RISC-V and a memory controller to use the 128MB memory?

gregdavill commented

Yep, that's exactly how I've been using it!

I've been using LiteX (https://github.com/enjoy-digital/litex) + LiteDRAM (https://github.com/enjoy-digital/litedram).
This makes it easy to create a Vexriscv + Memory Mapped DDR3 memory controller + cache.

I'll be publishing an example of how this all works.

Cool thanks.

You mention 0.2 going under a short production run soon. Does that mean you will be willing to sell assembled boards? I could make pcbs but soldering those bga and other chips at home is a challenge to say the least.

Ahh, yes.

You can now join a groupbuy for boards here: https://groupgets.com/campaigns/710-orangecrab
The boards will be fully assembled by a assembly house in the US.
