Hi Sir,
Our customer request a ASIL-B compliant MCU, and we found that S32K144 can meet the requirement.
But we have one question about the software, whether we can use the S32K FreeRTOS bsp and meet the safety requirement ?
or we should safety pre-certified software then the MCU can really reach the safety level ASIL-B?
If S32K need Pre-certified software to meet ASIL-B requirements, what software vendors are your suggestion ? AUTOSAR or others.
Thanks
Jack

Hello @chen_jackcw,
It depends on the safety concept and requirements alocated to S32K, if you have safety requirements allocated to S32K1 and running an OS on it, then, you need an ISO compliant OS.
The FreeRTOS is an open source SW and NXP provides it as a reference SW without any safety certification.
You can use SafeRTOS:

Also, some of our partners like Vector, Elektrobit provide safety certified Autosar stack and OS.
