Hi Andrew
I'm aware of that development, the idea is to expand them.
I wrote C and micropython drivers for many FPGA-implemented peripherals,
including high resolution graphics, USB mouse/keyboard, audio, etc.
The idea is to maintain that and to support as much peripherals/boards as
possible

We are actively moving the litex support forward, with both flat and kernel

FPGA development boards are indeed not cheap, as the chips themselves are
expensive. But those of us who are in the field know some solutions. Indeed

Hi Victor,
Yes, as I said before I also think this is a very important field, but at
least for this chinese board I realized that things are not there yet.
Maybe using a Lattice FPGA could work better, but anyway, a good FPGA board
to run a RISC-V is not too low cost.

No, as we pointed out, it is a long term project that needs to be well
thought out.
You listed many possibilities, we need to define a goal and focus on it.
Let me share my (bad) experience with FPGA:

BTW, I suggest you change the Subject to something related to NuttX and

Hi Tomek,
Thank you for raising these good points and thank YF for suggesting it.
I also don't know much details about it, maybe I think at list on Linux we

work correctly.

Yes! exactly like that. But with better maintenance, being able to run on
many boards, and more interesting peripherals (video, mouse, etc.)

Roger that :-) I was thinking about experiment like in "Sphery vs.
Shapes" to convert NuttX code to FPGA LUT directly with no CPU.. but
if that makes no sense then probably Open-Source RISC-V would be the
best choice and there are some ready to use implementations that could
constitute our referenc
The innovation won't be to run NuttX in a RISC-V (soft-core or not) but
using a FPGA for its flexibility to add any kind of peripherals, one of the
main ones to be useful in my view will be a high-resolution framebuffer and
USB mouse/keyboard for a complete UI
On Sat, Jan 27, 2024 at 4:31 PM Grego
Aren't most CPUs available as soft cores? Certainly Xtensa was intended
for that purpose. ARM and MIPS have been common soft cores in ASICs for
more than a decade. As is RISC-V soft core in FPGAs.

In the past, there was some interest in ports
Tomek, as I clarified, porting NuttX to a FPGA will require a soft-core
CPU. I don't envision an opertaing system without a CPU, I see that like a
bad design choice if possible at all
Using a soft core and custom peripherals seems more valuable, even
including video output and USB host for mouse/ke
Hi Tomek,
AFAIK, compiling the NuttX to run inside an FPGA is not a kind of task to
be done in a GSoC project, it should be a long term effort (if John Keynes
allows us).
Also keep in mind that currently NuttX RTOS is supposed to run on top of a
processing unit (Microcontroller, Microprocessor, e
Okay Victor, I was thinking about toolchain that you present in
"Sphery vs. Shapes" [1] to be adopted for NuttX on FPGA conversion
without a CPU design.. could you please send your full detailed
proposal then? :-)

Just clarifying, the idea to run NuttX on a FPGA is to instantiate a CPU
and peripherals on the FPGA and then run normally as if it were a MCU
Good thing is that you can change the CPU, add/remove peripherals, etc.

Hey there Victor! Thanks for your interest in NuttX port to FPGA!! :-)
No there is no such design yet.. you would have to create everything
from scratch.. so there is some serious amount of work to do.. but
imagine the results.. there will be just one step to ASIC!! :-)
I could reconsider my men
I can certainly port NuttX to run on some FPGA boards too
Is any board already supported?

Yes, and that toolchain could be used to cross-build NuttX ROTS to
FPGA without a CPU with amazing efficiency as proved on x86
architecture!
Hi Tomek,
His toolchain is focused on FPGA, but he is interested in participating in
other projects for GSoC.
Also we need NuttX mentors, I will participate, but for each project we
need two mentors, please let me know who could be interested to help.
