<< I think it could be very useful if integrated with CI. We could find many issues that aren't detected currently. >> Thanks Alan, that's a great idea! Lemme find the best way to integrate Automated Testing into the CI, without breaking our PR Submissions. If a PR breaks the CI: Maybe we can run an "Auto Triage" to guess the Severity of the Breakage? Like: (1) Code Red: "Most likely the PR Code broke the CI, please fix the PR" (2) Code Amber: "Maybe the PR Code broke the CI? Needs more investigation" (3) Code Green: "Probably OK" (e.g. unable to download OpenAMP, automated test failed) Right now I'm running the Automated Test every morning (GMT+8). So I have the rest of the day to figure out what broke, without staying up all night :-) Lup On Sun, Jan 28, 2024 at 7:36 AM Alan C.

[Article] NuttX on Ox64 BL808: Automated Testing with Ox64 Emulator
Every day we’re auto-building NuttX for Ox64 BL808 RISC-V SBC... Can we test NuttX on Ox64 automatically after building? Yes we can! With a little help from the Ox64 BL808 Emulator that we created last week. In this article, we fill in the missing pieces of our Ox64 Emulator and run it for Automated Testing... (1) Booting NuttX in Supervisor Mode (instead of Machine Mode) (2) Emulate OpenSBI for setting the System Timer (3) Emulate the UART Interrupts for Console Input (4) Execute everything with Expect Scripting (based on TCL) (5) Which becomes our Daily Automated Testing (triggered every day by GitHub Actions) Here's the article: https://lupyuen.codeberg.page/articles/tinyemu3.html Lup

Re: [OT] Projects for GSoC 2024
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 reference NuttX@FPGA design.. the goal here probably would be to run on smallest possible LUT count or something with amazingly better performance than out-of-the-box hardware? :-) Let Victor / PMC decide on the task specifics and priorities, sorry for the noise folks :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info On Sat, Jan 27, 2024 at 8:18 PM Victor Suarez Rovere wrote: > > Tomek, as I clarified, porting NuttX to a FPGA will require a soft-core > CPU.

Re: [OT] Projects for GSoC 2024
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 Gregory Nutt wrote: > Aren't most CPUs available as soft cores?

Re: [OT] Projects for GSoC 2024
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, etc), it is not a simple state machine that can be emulated easily in FPGA. So, it should be something completely different. But of course, maybe there are some shortcuts that I'm not aware of. BTW, Victor is also interested in participating in other projects that are related to other areas of interest (i.e. Graphics, like X11 support to let NuttX run Unix/Linux graphics applications).

Re: [OT] Projects for GSoC 2024
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? :-) [1] https://www.youtube.com/watch?v=hn3sr3VMJQU -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info On Sat, Jan 27, 2024 at 7:22 AM Victor Suarez Rovere wrote: > > 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. > > On Sat, Jan 27, 2024 at 12:32 AM Tomek CEDRO wrote: > > > Hey there Victor!

Re: AVR32 on NuttX
Dear Alan, Dear NuttX community, greetings! > Nice to see they added JTAG support to avrdude, but only few AVR8 > has JTAG support (i.e. Atmega128 has). I trust you're all doing so well. I revisited the NuttX codebase today. I created a sample at32uc3b0256 (avr32dev1) Microchip Studio project to see if I can import the relevant NuttX files. It is time consuming. I downloaded NuttX 10.1.0 RC-1 and Apps 10.1.0 a couple of hours ago. I invoked "make V=1" to see the details. I have isolated the core files (including libs) responsible for the build. I am just working with the assumption that not a lot has changed between 10.1.0 and the current master branch with regards to AVR32. I know this approach is a bit tedious. If I can prove avr32dev1, Mizar32 is not very far away from there. I wanted to specifically write to you to check if anyone else from the community has already furthered (OR in the process of) NuttX in the context of AVR32. I just want to avoid duplication of effort. May I proceed this way? At least we'll know why avr32dev1 won't boot with the current state of things. My best regards to all. R P.S. Just wondering: would "make export" help in my case?
