TMS320C6678: Emif16 interrupt

Part Number: TMS320C6678
Other Parts Discussed in Thread: TMS320C6748

Hi,

How to generate a emif16 interrupt to the DSP. I have read this article section 3.10

http://www.ti.com/lit/ug/sprugz3a/sprugz3a.pdf

But how to map emif16 interrupt to DSP, i didn‘t find input event both in figure7-32&7-38&7-39 in TRM. Only EASYNCERR system interrupt could be found. Please help analyze in detail.

Hi,

You should also configure the CIC: www.ti.com/.../sprugw4a.pdf

The following wiki provides quite useful information for configuring interrupts on Keystone devices:

Hi,

Thank you for your reply. But what i want to know is the event number related to emif interrupt which could map to cpu interrupt. I could find the interrupt name in tms320c6748 datasheet. So what abut tms320c6678?

Hi Nancy,

I think it is event #61 in Table 7-41 CIC3 Event Inputs (Secondary Events for EDMA3CC0 and HyperLink) (Sheet 3 of 3):
61 DDR3_ERR DDR3 EMIF Error interrupt

Let me check that further.

Hi,

You are checking about the EMIF16 interface. The interrupt is "EASYNCERR" in C6678 datasheet, "128 EASYNCERR EMIF16 error interrupt".
