RTOS-based development varies significantly from RTOS to RTOS, so I’m not sure how much it’d help to learn to use one. On the other hand, most fundamental OS knowledge is fully transferable to RTOS, so that would be helpful for embedded developers to understand.
Yes, there’s a ton of specificity. Could probably say that about kernel dev too. But there is a ton of things people do that’s a lot more generalized. Of course I’ve used very little of specific things I got tested on in my day to day over the years.
