risc-v wfi problem



  • i check the standalone-sdk,the k210 have 2 cores,default is core0,core1 is busing doing while(1).dose it save power if the core1 is in halt mode (waiting interrupt state).
    how dose the k210 implement,when i send soft interrupt,no wake to continue or soft interrupt handler run???

    It does not save power when core1 is in halt mode.
    K210 will be waked up then handle soft interrupt when you send soft interrupt if k210 is waiting for interrupt(wfi).
