IWR6443: MSS support for EDMA CC1

Notozman

Part Number: IWR6443

Team,

Can you pls confirm that EDMA CC1 is able to be connected (for interrupt / completion events) to the MSS ? It seems only CC0 is included in the MSS VIM config but don't know if this is due to default software mapping or fixed hardware reasoning.

Thanks.

Hello

Only the TCs for CC0 and connected to MSS_VIM triggers.

Please see the IWR14xx/16xx/18xx/68xx/64xx Industrial Radar Family Technical Reference Manual (Rev. x)

Table 3-11 InterruptRequestAssignments

One way to work around this would be to use the DSP events to make DSP write soft interrupt to MSS.

Hope that helps.

Thank you,

Vaibhav

Thanks Vaibhav,

So you are saying that we cannot modify the allocated presented in table3-11 ?

The column heading in the table is "Default VIM Interrupt Channel" which might indicate that other options might be possible ?

Hi Greg

That is right. The name is misnomer. - these are hard wired lines from modules to VIM inputs.
