NuttX poster?
At this year's Community over Code Europe 2024 (formerly ApacheCon), there is an opportunity for PMCs to submit posters to be on display in high-traffic areas throughout the conference. This could be particularly applicable if a project has a major new release, new algorithms, novel use of existing technologies, etc. It would be cool if the NuttX PMC could submit a poster to increase awareness and interest in our project by showcasing something unique about us in an artistic way. Do we have any artists among us who would like to put something together? Please speak up, and I'll help by coordinating with the organizers. Cheers, Nathan

That's good news. I missed that somehow. Hopefully it means that I can go ahead and delete some custom application code!

Re: STM32H7 board with ethernet
The network monitor is part of apps/netutils/netinit so it is not a part of NSH. NSH can automatically perform the network initialization if so configured and which, optionally, starts the network monitor thread. But the logic is not architecturally a part of NSH nor does it depend on N SH.

Re: STM32H7 board with ethernet
Hi, I agree, but we should make progress on several points before it's possible : -how to configure it at runtime in a modular manner that can be customized by the user? It's usual that we need a choice of fixed ip or DHCP. config file? runtime commands like nmcli? How to store the config? DHCP itself should be cancellable if the network goes down while the DHCP request is running. -how to start it? This requires a boot script so the daemon can be started in the background while NSH runs. This is not generic NuttX way to do things, many systems dont actually require this. -how to get feedback from it? We have developed a message bus that notifies other apps, but this is also user-specific. So I dont see this being agreed upon in a way that pleases everyone soon :-) This is putting a foot in the "userspace initialization" which has always been user-specific in NuttX. On the issue of boot scripts, there is also an important change that would be nice to have upstream: Split the nsh ability to mount a romfs (or any fs) and the nsh ability to run different kinds of logon scripts. For the moment this is tightly coupled at the kconfig level. This separation is more unix-like: the shell program should not mount stuff as a built-in feature, but do that as part of a some flexible config. This is probably controversial so I wont defend this opinion unnecessarily. There are RTOS situations where we dont need/want these features. In our boards the romfs is mounted by the board, so our nuttx own apps already have this change.

Re: STM32H7 board with ethernet
The phy on the nucleo-h743zi is supported, I have it working in an industrialized product. It does not have an interrupt line, so cable state detection requires a polling daemon. However, the default network configuration provided in NuttX examples is cumbersome and too much linked with NSH It can work for simple tests and demos, but you will have to write a proper network management daemon if you plan to use more than one network app. Sebastien Le 06/02/2024 à 14:19, Alan C.

Re: STM32H7 board with ethernet
Hi, I see that only the 743zi is in the tree, but it should not be too hard to clone that, change its config entries, and use it. Only a "nsh" config can be enough to start. This CPU is also not explicitly supported, but the H753Z is present. You can add the missing entries in kconfig, after checking the hardware differences, which should be minor, and use that for your board. Even if this is missing minor cpu features it could be a good place to start. Then you can contribute it back if you wish.

Re: [Article] Build & Test NuttX Apps in the Web Browser (TCC RISC-V Compiler)
Hi, This is cool. Two remarks: - it would be nice to have tcc supported as an official compiler along gcc and llvm. Probably just for fun with no "commercial interest" for nuttx. - in the 80s, CP/M had C compilers that executed in less than 64k of RAM... Sebastien.

We have a couple of issues that might affect TCC Compiler on NuttX: (1) RISC-V Registers are mixed up when TCC emits code for NuttX System Calls: https://lupyuen.codeberg.page/articles/tcc.html#appendix-nuttx-system-call (2) TCC won't link with NuttX Libraries compiled with GCC. We'll have to recompile the NuttX Libraries with TCC: https://github.com/lupyuen/tcc-riscv32-wasm#fix-missing-printf-in-nuttx-app (3) TCC for RISC-V hasn't been updated for the past 8 months: https://github.com/sellicott/tcc-riscv32/commits/main/ Perhaps our article will revive the TCC project? Let's see what happens :-) Something interesting popped up: Our NuttX ROM FS Driver works well in WebAssembly. Which means we can run it to host a ROM FS Filesystem inside a Web Browser! https://github.com/lupyuen/tcc-riscv32-wasm#rom-fs-filesystem-for-tcc-webassembly TCC Compiler in WebAssembly needs a filesystem (inside the Web Browser) that's preloaded with C Header Files and Library Files.
