Interrupt Callback for DMA in MPC(Multiple Parallel Conversion) not getting generated (DMA trig).

Hello,
(For (S32K396))
The below mentioned signals are connected to the respective ADCs as per the below table:

Signals	ADC	CL attributes	FIFO
SIN_P	ADC3_P2	List Start	FIFO 1
COS_P	ADC5_P0
SIN_Inv_P	ADC3_P1
COS_Inv_P	ADC5_P1	Last channel

Here, BCTU shall be triggered and data from the above ADCs shall be stored in FIFO1 which shall be further be accessed through DMA.

Currently through debugging it can be observed that BCTU is getting triggered, FIFO is getting updated, source and destination for DMA are as expected, interrupt is also enabled but interrupt callback mentioned in DMA is not getting trigger.

Please check the below doc.("Configurations.docx") for all the respective configurations.

Hello @AkhileshBelore,

Did you enable the DMA interrupt in the Interrupt driver?

SOLVED.
Had missed updating "Dma Mux Source"
