The #SpaceWire ( #satellite oriented wired communication standard) #OpenSource #GNU/ #Linux software support (C library, CLI, Python) for Remote Memory Access Protocol ( #RMAP ) initiator and target realized by STAR-Dundee RMAP IP Cores integrated into custom variant of TEDIA PCD-8006 PCIe expansion card developed by Kyaw Htet Lin at #CVUT #CVUTFEL and his related thesis have been published.
The project page https://gitlab.fel.cvut.cz/otrees/spacewire/spw-pcie-tedia, Wiki, Thesis PDF, Presentation PDF and complete record with review reports https://dspace.cvut.cz/entities/publication/490357d1-8609-414e-91ad-87d4cc0e9b7e.
Longer term plan is to continue with support of more SpW IP cores, #RTEMS and #Zynq and #BeagleV/ #BeagleVFire with potential to be used even for space qualified #PolarFire #SoC.

Michal Lenc will present about his #CANbus subsystem integration into #RTEMS space grade system on #LinuxDays on on Sunday October 5 from 11:00 CEST. This time in the Czech language. See the entry. The article presented at International CAN Conference is there, RTEMS mainline documentation, more information at CTU FEE CAN projects site. Update: Recording (in Czech)

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.

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 interested in thesis to add MMU to #QtRvSim
- Matyáš Bobek, FlexCAN Controller Emulation for QEMU, #qemu #canbus (git), I hope for mainlining soon, my thanks to

We will present our new #canbus (CAN/CAN FD) stack for #RTEMS (https://www.rtems.org/) on #CiA_iCC https://old.can-cia.org/icc in Baden-Baden on Wednesday 15. The stack is based on our LinCAN Linux driver (initiated in 2003 as part of https://ortcan.sourceforge.net/ ). The new code source and documentation is available at https://gitlab.fel.cvut.cz/otrees/rtems/rtems-canfd . Our presentation "Scheduling of CAN frame transmission when multiple FIFOs with assigned priorities are used in RTOS drivers" is relevant even for future Linux #SocketCAN stack to solve its long standing link level priority inversion problem at least for some controllers when multi-queue support is implemented and our previous QoS work is updated. The measured latency results on #zynq on #RTEMS are great and in order better than maximal ones on PREEMP_RT Linux https://canbus.pages.fel.cvut.cz/#can-bus-channels-mutual-latency-testing . So there is lot to do on Linux side as well.

#RTEMS is another great #OpenSource projects, is #OS still used in many field but mostly in the aerospace. cool #GPL
https://en.wikipedia.org/wiki/RTEMS -
what operation systems are used in space? Nice article about RTOS
