The safety certifications are particularly interesting. It's a lot of work to develop "safe software" - that is software that is developed according to a safety standard and certified to a "safety integrity level". Having an RTOS which is both open source and safety certified is pretty great.
They say they want to maintain the certifications - that will be tricky unless there's some investment coming from somewhere. It's a lot of fairly bureaucratic work to understand the safety standards, put the right development processes in place and maintain those as your software changes. It's not nearly as simple as just writing code and running it. It's definitely not the kind of software development someone would do as a hobby. I hope Microsoft are going to fund some of that development effort.
Interestingly although FreeRTOS isn't safety certified, SAFERTOS (https://www.highintegritysystems.com/safertos/ https://www.highintegritysystems.com/safertos/) is - which is a commercial implementation with the same APIs.
- MegaDeKay 3y agoYes, that ongoing certification will be costly but they mention the support of companies with pretty deep pockets: "In addition to the project, we are also announcing the creation of an interest group focused on developing an industry-supported, sustainable funding model for ThreadX. We are excited that AMD, Cypherbridge, Microsoft, NXP, PX5, Renesas, ST Microelectronics, Silicon Labs, and Witekio (an Avnet company) have all committed to supporting this conversation"
- demondemidi 3y agoThis is huge. Automakers won’t touch something unless it is iso 26262, and it commands a 10x premium. It is very hard to functional safety right, and this compliance is a key component in enabling tier 2 manufacturers.
