AM6442: A53SS0 GIC (Generic Interrupt Controller) does not wake up

Part Number: AM6442

Hello,

I cannot wake up the GIC (Generic Interrupt Controller).

"GICR_WAKER, Redistributor Wake Register" was used to release the wake-up (GICR_WAKER.ProcessorSleep=0).
However, it does not change to "GICR_WAKER.ChildrenAsleep=0".
I checked with other Cortex-A53 and confirmed that it can work by setting the GIC clock.


Is there any other setting I need to do?

Best Regards,
Shinji Tonoshita

    Hello Shinji-san,

    I think you are saying that you are able to use the GIC using one core, but you are having trouble using the GIC with another core. Is that correct?

    Please provide additional details. Which core is having trouble using the GIC? What software are you using on each core? What version of software is being used?

    Regards,

    Nick
