DRA829V: interrupt by switching the pin of GPIO0_0 to EXTINT

Kenley

Part Number: DRA829V
Other Parts Discussed in Thread: DRA829

Hi team,

My customer plan to use interrupt by switching the pin of GPIO0_0 to EXTINT. When EXTINT is set, can interrupt be used with the following interrupt number ？

Interrupt ID: A72 Core: GIC500_SPI_in_37 (graphical_EXT_INTN_glue_EXT_INT_LVL_0)

R Core: R5FSSx_corex_INTR_in_13 (DRA829_INTNO_VIM_graphical_EXT_INTN_glue_EXT_INTN_LVL_0)

Thanks and best regards,

Kenley

I believe by switching you mean that you are setting mux mode 0 for AC18 instead of mux mode 7?

I see R5FSS0_CORE0_INTR_IN_13 mapped to GLUELOGIC_EXT_INTN_GLUE_EXT_INT_LVL_0 but GIC500_SPI_in_37 is mapped to MMCSD2_EMMCSDSS_INTR_0 and not to the external interrupt.

Can you elaborate on the use case and provide more details? Do you want to interrupt the A72 and the R5F using an external interrupt and looking to confirm the interrupt numbers?

Regards

Karan

Hi Karan,

Thank you for your support!

Yes, the setting is in mode 0.
That's right, they want to interrupt A72 and R5F using external interrupts, so they would like to check the interrupt number.

Thank you in advance.

Best regards,

Kenley

Hi Kenley,

Apologies for the delay in reply. Is this still an open question?

If it is, then interrupt routing numbers can be found in this documentation: https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/j721e/interrupt_cfg.html

Kenley, Takuma

If the idea is to interrupt using the external interrupt instead of the GPIO. IMO, these interrupts are direct interrupts to cores and not routed via the interrupt router as mentioned in tisci doc..

For A72:
