ChibiOS Free Embedded RTOS

Hi, just doing some investigating/costing for a contract I'm working on. There's a good chance the project will fall into the free-commercial area (or even GPL potentially), but I wanted to have all the information:

• The prices here are from 2020, are they still accurate?
• The free commercial says it has some limitations, what are those?
• The OSLIB component is priced separately, but it looks like from the os/rt/rt.mk and os/nil/nil.mk it is used unconditionally (or am I misreading something)? This is more out of interest, as I believe either way this project would use heap and mbox (via lwip).

Thanks,
Dave

Hi,

- Prices are accurate so far.
- Free commercial requires to advertise use of ChibiOS and code is read-only (no changes in the commercial parts, Apache 2.0 parts are fully open). You can also extend beyond 500 cores by re-registering.
- OSLIB is always included, the check is when features are enabled. Heap and MBoxes are OSLIB features. We are considering making RT and OSLIB one again in the future, I think it is just making things more confusing.
