Our series of tutorial about NuttX is increasing fast! Many features are already covered!

Yes! People coming from Unix and Linux feel at home on NuttX! ;-)

True, and NuttX is replacing RTEMS for space exploration as well: https://developer.sony.com/posts/apache-nuttx-powers-worlds-...

Not really....one use-case = replacing? ;(

All replacement start with the first entity using a new technology. Soon ESA, NASA, ISRO will start using it. China already uses it, the SPARC V8 port was done by them! ;-)

I really hope your in stock trading, you must be successful like hell with your crystal-ball ;)

I think the best way to compare is trying NuttX and others RTOSes on some supported board (raspberry pi pico, esp32-devkit, stm32f4discovery etc). As rzr said NuttX is easier for people with Linux background, because it is Linux-like. So the way you mount a MMC/SDCard is the same, the way you search for devices using i2ctool is the same, etc.

I'm not sure I follow. Why would I want to "use" an mcu board the same way I use my linux desktop? It's not like I'm going to dynamically mount an SD card from a CLI for such an embedded device. Or that I would want to have a CLI at all. It is designed for early prototyping?

You don't have to mount it dynamically if you don't want. You can use it in a very static way, like your baremetal way to do things. But you can also have option to do it dynamically, case you have different SDCards with different binaries to load (yes, NuttX support dynamic ELF loading as well).

Exactly. You can prototype heavily and make sure peripherals, firmware programming, etc is working/to your advantage before doing any pcb work

That said bigger mcu,mpu +fpga type devboards will still absolutely price out hobbyists

The best description is UNIX like, because NuttX is POSIX based, while many RTOS aren't.

Thanks for sharing! Yes, the NuttX International Workshop was amazing!

I am finishing the video editing of the lecture recordings and it will be available on NuttX Channel at YouTube. Stay tuned!

I'm a big NuttX lover, this is exactly what I was looking for microcontrollers. After spending many years using uClinux , FreeRTOS and others.

NuttX is a kind of Linux-like RTOS. It is very easy to use, as you can see on my video tutorials: www.youtube.com/c/NuttXChannel

Unfortunately using a GPL/LGPL is not an option for embedded system because companies want to keep part of their devices closed.
