#nuttx — Public Fediverse posts

The #cvut #cvutfel OTREES booth at InstallFest 2026 #InstallFest There are #Linux and #NuttX running on x86 PC, RISC-V and ARM. The #QtRvSim simulator is running on x86 and RISC-V Milk-V Pioneer. We have there APO course students semester projects running on MZ_APO. #pysimCoder on the screen as well. The NuttX introductory workshop has been visited by many people. All STM32L476RG based NUCLEO-L476RG kit graciously provided by STM and ETC - Embedded Technology Club.

The article Design of Prototyping Control Unit for BLDC/PMSM Drives and Piezoelectric Actuators documenting our work on #NuttX #RTOS and #pysimCoder has been published. It documents SaMoCon Open HW and SW motion control platform as well.

We have submitted another related presentation to the Apache Community Over Code 2026 in Glasgow, from October 10 to 15. The NuttX call for presentations is still open for this event.

We hope to be available on Open Source Summit Europe in Prague in October, if the price bar/access rules allow that to our students and us, and we will be available (for sure) at #LinuxDays in Prague, which is (in a contrast) a really freely accessible community organized event in Prague with long history, and this year exactly before @linuxplumbersconf and Open Source Summit Europe

OTREES #cvut booth at #LinuxDays 2025 presenting our CAN/CAN FD projects for #Linux, #NuttX, #FPGA and #RTEMS. SaMoCon motion control platform driven by pysimCoder rapid prototyping solution for #NuttX with online monitoring and parameters tuning and update uploads through silicon-heaven and NXboot integrated in the frame of Štěpán Pressl’s #GSoC 2025 (will be presented in detail on NuttX Workshop October 16 and 17). More on the booth: #Espressif based kits running NuttX (ICE-V Wireless, see our PMSM project, #ESP32C6 with M-bot platform), AMD/Xilinx Zynq MZ_APO running Linux and #RTEMS, PolarFire SoC, Milk-V Pioneer 64 core 64-bit #RISCV system running #QtRvSim (for CompArch education), #CHROMuLAN data acquisition over uLAN driver, LX_RoCoN system used for ESA projects and lot more to see at our booth.

#NuttX Support for IEEE 802.3-2022 10BASE-T1S/L #Ethernet using Open Aliance SPI MAC-PHYs implemented by Michal Matias from #CVUT in frame of #GSoC2025 has been fully merged into NuttX mainline. The common part resides at drivers/net/oa_tc6. #ESP32C6 mapping and mapping for SAVM71-Xplained Ultra are good examples for straightforward extension to other MCU and board NuttX SPI interfaces. The accompanying plcatool for Physical Layer Collision Avoidance parameters configuration matching OA-TC14 specification is another contribution.

Гайд на сборку OpenVela для STM32 из-под WSL от 16-летнего отрока

В этой статье мы соберем ОСРВ OpenVela от Xiaomi под отладочную плату STM32 F411CEU6, используя WSL, который официально вроде как не поддерживается. Эта ОС базирована на Apache Nuttx и имеет много фич от Xiaomi, включая HyperConnect. В комплекте также небольшая предыстория от автора. Цум Интрестинг

Summer 2025 #cvut defended theses by OTREES/my students:

• Matyáš Bobek, FlexCAN Controller Emulation for QEMU, #qemu #canbus (git), I hope for mainlining soon, my thanks to
  @marckleinebudde for review
• Albert Bezděk, Stereo Camera FPGA Interface and Processing for Zynq Based Systems, with initial rectification and disparity in #XilinX #Zynq #FPGA (git), thank to Martin Meloun for review
• Michal Matiáš, NuttX RTOS Driver for Single Unshielded Twisted Pair Communication, working with ncv7410 and ESP32-C6 for now (nuttx, apps git), continues by #GSoC expected to lead to broader OpenAlliance SPI Ethernet MAC-PHY T1S for mainline #NuttX support after summer, thanks to @cynerd for review

See the last OTREES theses list for link to repositories and more

Another related theses from #cvut Faculty of Information Technologies mentored by Michal Štepanovský to mention:

• Jan Medek, Implementation of RISC-V soft-core processor on FPGA board with real-time operating system support, port (git) of #NuttX to the own setup of Ibex #riscv to Digilent Basys 3 and Digilent Nexys Video, includes even #NuttX, #RTEMS, #Zephyr, #FreeRTOS and RT-Thread choice analysis, some minor clarifications in my review, out of the text documentation, the student ported NuttX even to the CPU system prepared in frame of the next thesis
• Ondřej Golasowski, RISC-V open-source microarchitecture analysis and optimization, the VESP-BETA single-cycle RV32IMZicsr #riscv design for basic #comparch education with #FPGA labs

Stay tuned next summer as well, there is student interesting in thesis to add MMU to #QtRvSim

"Yes, you heard it right: Apache NuttX now supports the Python interpreter on ESP32-S3!

NuttX is a platform that can run applications built with programming languages other than traditional C. C++, Zig, Rust, Lua, BASIC, MicroPython, and, now, Python."
