Using the Rust standard library with the NuttX RTOS

Interesting. RTOS is a major embedded ecosystem component that rust currently lacks.

For anyone not familiar: NuttX is notable as the RTOS used on the open-source PX4 flight controller firmware, which is ubiquitous in commercial UASs.

https://arewertosyet.com/

has a big list. The definition of what is an RTOS and how much is in software vs hardware is a blurry area.

Actually, Rust embedded ecosystem exists and is amazing. It’s a breath of fresh air after having to use vendor SDKs from ST, Nordic, and even Raspberry Pi.

Embedded ecosystem != RTOS

There are plenty of options that are realtime-capable.

The espressif ESP-IDF sdk that is using FreeRTOS underneath has rust + std support for quite some time now.

There is embassy and rtic, albeit they are quite lightweight

I use RTIC - I suppose this is a matter of categorization; I consider it an interrupt-wrapper that manages locks.

Rust has some very competent RTOSes already like Tock / OxidOS and PikeOS. It's great to see support for NuttX, but it's Rust isn't completely lacking for options here.
