AM625: Interrupt connections between different domains

Daisuke Maeda
Guru 20205 points
Part Number: AM625

In other thread, it is mentioned that M4F can support only polling mode for the MAIN domain peripherals.

e2e.ti.com/.../am625-using-uarts-on-the-main-domain-by-m4

Does it mean that the interrupts from the MAIN domain peripherals are not connected to M4F why only polling mode is supported?

In "Figure 10-1. AM62 Interrupt Architecture" on the TRM, the interrupts from the MAIN domain peripherals appear to be connected to M4F.

On the other hand, are the interrupts from the MCU domain peripherals connected to A53?

Best regards,

Daisuke

    Dear TI Support Team,

    For M4F, the interrupt sources from the Main domain peripherals do not appear to be included in "Table 10-12. MCUSS NVIC Interrupt Connection" on the TRM.

    I understand that the interrupts from the Main domain peripherals are not connected to M4F.

    For A53, the interrupt sources from the MCU domain peripherals appear to be included in "Table 10-13. GIC Interrupt Connection" on the TRM.

    I understand that the interrupts from some MCU domain peripherals are connected to A53.

    Is my understanding correct?

    Is the interrupt from CAN-FD in the MCU domain not connected to A53?

    Please give me an answer as soon as possible. Your prompt reply would be appreciated.

    Best regards,

    Daisuke

    Table 10-18 (10.1.13 Interrupt Connections Summary ) , page 8561 has the summary

    https://www.ti.com/lit/ug/spruiv7/spruiv7.pdf

    MCU MCAN interrupt does not go to the GIC/A53.

    Hi Mukul-san,

    Thank you for your reply.

    I will check Table 10-18 on TRM.

    Best regards,
