Interrupt distinction

Michi Yama
Guru 10030 points

Hi,

I would like to know how to distinguish the interrupt to A8 Core.

My customer would like to know the kind of one interrupt. It happens when OS booting(WEC7).

But the interrupt is inside of A8 core. So they can't distinguish what the cause of the interupt is.

Is it to possible to distinguish using by CCS?

Please let me know.

Best regards,

Michi

    Hi Michi,

    We have 128 interrupt requests (0 to 127) towards the Cortex-A8 interrupt controller. See AM387x TRM, Table 1-96. Cortex-A8 MPU INTC Interrupt Mapping.

    Can you tell the Interrupt Number (0 to 127) of the interrupt that happens when OS booting? If the interrupt is inside of Cortex-A8, so it should be one of the first four interrupts (0 to 3):

    0 EMUINT CORTEX-A8 Cortex-A8 Emulation Interrupt
    1 COMMTX CORTEX-A8 Cortex-A8 Emulation Interrupt
    2 COMMRX CORTEX-A8 Cortex-A8 Emulation Interrupt
    3 BENCH CORTEX-A8 Cortex-A8 Emulation Interrupt
