Can anyone here put NuttX in some sort of usage context with other RTOSes? Put another way: if one were to learn an embeddable RTOS for first hobbyist and then perhaps professional purposes, where is NuttX in the hierarchy of things you would recommend learning? It looks fascinating and well thought out, but I have no way to assess how much of a backwater, dead end, quirky solution or solid choice it might be.

Samsung uses a fork of it. https://github.com/Samsung/TizenRT https://github.com/Samsung/TizenRT

  Ahhh... now that's the sort of information I was interested in hearing! Thanks.

NuttX seems to have a stronger mandate to be POSIXy than many other RTOSes and includes a shell that's similar to a unix shell. Where the interface and "shell" for other RTOSes is often more unique and doesn't have as much of a unix feel. So it might be a more comfortable transition, though I'm sure that approach has it's drawbacks also.

  If you want a POSIX environment in an RTOS, RTEMS has had a fully compliant POSIX C and C++ interface with decades of spaceflight usage. However, it remains somewhat obscure in terrestrial usage.

Zephyr RTOS has a bigger community.

I also asked myself the same question. There is some useful information at the bottom of this redit thread: https://www.reddit.com/r/embedded/comments/w5cq50/zephyr_vs_nuttx_could_you_tell_your_experience_on/ https://www.reddit.com/r/embedded/comments/w5cq50/zephyr_vs_...

Random tidbit: there is a developer making an "OS?" With it for pinephone, has a really cool blog (cool illustrations) will post link at desktop https://lupyuen.github.io/articles/usb2#pinephone--nuttx--feature-phone https://lupyuen.github.io/articles/usb2#pinephone--nuttx--fe... oh lol OP is the same person my bad
