Hello TI Team,

Now , our project team is discussing how to implement functional safety without using Autosar-OS and safe-RTOS

I think that this may be a big topic, but I also hope to get the opinions of experts.

What are the key differences between TI-RTOS and Free-RTOS?

If we want to use Ti-RTOS or Free-RTOS to meet functional safety requirements, which choice is better?

Or neither?

Best regard

Hi,

The TI-RTOS documentation is available at below link:

SYS/BIOS (TI-RTOS Kernel) User's Guide (Rev. V)

TI delivers FreeRTOS based SDKs. Information for FreeRTOS can be found in TI online user guide at below link, which in turn has multiple links to FreeRTOS resources.

4.2. FreeRTOS — Platform Development Kit (PDK) - JACINTO User Guide (ti.com)

WHIS provides SafeRTOS and has several tutorial pdf documents and videos on their website that introduce SafeRTOS and provide overviews on typical operations

A safety certifiable HLOS would provide a easier path to safety certification for your solution. Regarding TI-RTOS vs Free-RTOS as a starting point, there is a path with Free-RTOS to move to SafeRTOS for a safety certifiable OS. A similar path is not readily available for TI-RTOS.
