    AURIX TC27x Lockstep


    I don't understand the lockstep configuration of the AURIX Tricore TC27x.

    It is possible to run CPU 0 and 1 in lockstep mode. So does the Tricore has 3 cores plus 2 checker cores? Or do I have to configure one of the cores as master and one of the cores as checker core (so that two cores are doing the same calculations and one core is left to do something else)?

    Thank you and best regards!

    The checker core is not independent of the core it is connected too. The checker core can only be enabled or disabled. The TC27x has three cores (two of which can run with a checker core enabled).
