Integrating rustix on NuttX
Hi Rust experts, we are willing to integrate rustix on NuttX RTOS, the initial effort was done by rustix author: https://github.com/bytecodealliance/rustix/tree/nuttx but it hit the wall since we don't know the right way to integrate cargo with the old-school NuttX's Makefiles. Any help or suggestion is welcome. More about NuttX here: https://nuttx.apache.org and here: https://nuttx.apache.org/docs/latest/

Embedded Systems Weekly #116
Open Source Autopilot for Drone Developers PX4 is an advanced and open source autopilot flight stack for drones. PX4 can flight completely autonomously for pre-programmed missions, or, obviously, it can help a pilot who remote-controls the drone. It runs on NuttX RTOS.

How to contribute to open source or Linux kernel?
Microcontrollers are a good start. Boards are cheap and sensors are plentiful. You could get a yet unsupported board and port RIOT, Zephyr or NuttX.

Release v0.5.9.10 · embox/embox
Embox is a configurable RTOS designed for resource constrained and embedded systems. Embox main idea is using Linux software without Linux. (https://embox.github.io/ ) If you want use complex Linux Software and Linux is huge for your goals. Embox is the best idea, as I think. For example Embox is the only RTOS that allows to use OpenCV on Cortex-m MCUs https://www.embedded.com/benchmarking-opencv-on-stm32-mcus/

When do you know if your project needs to move on from bare-metal to using an RTOS? then from RTOS to using embedded Linux?
As for Linux, it allows easy and fast creating a device with reach features, but it requires more powerful and expensive hardware platforms, it has some questions with hard real-time, and it is less secure after all it is a general-purpose OS. We try to solve these cons of Linux in Embox. It combines prop RTOSes and Linux and allows run Linux software everywhere including MCUs
