The link goes to the overview page of i.MX 8X processors, but I could not find a specific reference to such a solution. It would great if you can point out where it talks of a certified/able system with Linux + safe RTOS.</P><P></P><P>The product portfolio is already confusing, the main <A href="https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i.mx-applications-processors/i.mx-8-processors:IMX8-SERIES">i.MX8 processor</A> page shows i.MX8X as a lower power variation with single GPU, however, under documentation of i.MX8X, there is <A href="https://www.nxp.com/docs/en/data-sheet/IMX8QXPAEC.pdf">this document</A>, which names variations such as 8QuadXPlus with more cores.</P><P></P><P>And I could not find documentation about how to use Resource Domain Controller for safety on i.MX8.</P></BODY></HTML> Wed, 22 Jan 2020 13:22:12 GMT https://community.nxp.com/t5/i-MX-Processors/Mixed-criticality-solution-with-Linux-and-safe-RTOS/m-p/977211#M145386 fatih_erol 2020-01-22T13:22:12Z
