Zephyr seems like the best shot at getting an open source RTOS in safety-critical environments, pretty exciting.
- bsder 7y agoFreeRTOS has a certified version, no?
- analognoise 7y agoYes it does.
- codetrotter 7y agoThe certified version isn’t open source though, is it?
- joezydeco 7y agoI’ve been developing on Zephyr for about a year now and “exciting” isn’t the word I would use here.
- sickcodebruh 7y agoCan you tell us about your experience with it?
- joezydeco 7y agoThe build system is a mess. Recently switched from GNU make to CMake and it’s still doing all kinds of weird stuff. Uses Devicetree to configure drivers but doesn’t use it like Linux, stuff gets munged into C #define macros and there’s no runtime access like a DTB section. Scheduler is still doing bad stuff, preemption is broken on certain architectures. There is no mainline Cortex-A port yet. Some chipmakers have done it but won’t share it. Drivers are constantly in flux. Ugh I could go on but won’t. I would label Zephyr as “FreeRTOS for when your boss says you can’t use Linux.”
- SlowRobotAhead 7y agoDoes that make FreeRTOS out to be FreeRTOS for when your boss says you can’t use Amazon?

- pjmlp 7y agoCan you say anything about how they supposedly achieve security and safety with C, as advertised on the website?
