I think Eclipse ThreadX is a great option (https://github.com/eclipse-threadx/threadx https://github.com/eclipse-threadx/threadx) Its might be the most used ThreadX on the market in the professional space (due to its history), but its quite frankly stupid simple to use. It was initially developed by Express Logic, then partnered tightly with Renesas, Then sold to Microsoft, and then transferred to the Eclipse foundation for good. They also provide NetX(duo), FileX, LevelX, UsbX and GuiX with full source and the same licensing afaik. Personally I don't care for UsbX or GuiX.
