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

Apache #NuttX International Workshop 2025 will be held on this Thursday and Friday (16-17th October 2025) https://events.nuttx.apache.org/ It will be accessible on site (Costa Rica - home location of original author, Gregory Nutt) and online. The NuttX RTOS is POSIX based alternative for processor systems and MCUs where Linux kernel does not fit. But thanks to following POSIX and Linux principles it allows writing applications (with some care) which are easily portable between GNU/Linux, NuttX, RTEMS and other real POSIX alternatives. The list of supported platforms is extensive. The #PX4 Autopilot project which is part of vendor-neutral https://dronecode.org/ operating under #Linuxfoundation umbrella. The system is used in lot of fitness tracker, some smartwatches, Sony earbuds, cameras on the Moon, industrial and automotive applications.

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.
