Cortex R8 Multicore core specific clock

Hans-Peter

For Cortex R8 with Multicore, can the clock frequency for each core be set Independent. Lets say first core runs with 1GHz and second core with 500MHz?

    Please refer to R8 TRM section 2.3.1 Clocking:
    CLK
    This is the main clock of the Cortex‑R8 processor. All the cores in the device and the SCU are clocked
    with a distributed version of CLK. It is also the main clock for the ETMs and the local CoreSight
    infrastructure.
