Hello,
(For S32K39-37 (S32K396))
The below mentioned signals are connected to the respective ADCs as per the below table: 

SignalsADCCL attributesFIFO
SIN_PADC3_P2List StartFIFO 1
COS_PADC5_P0 
SIN_Inv_PADC3_P1 
COS_Inv_PADC5_P1Last 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.

Had missed updating "Dma Mux Source"

Hello @AkhileshBelore,

Did you enable the DMA interrupt in the Interrupt driver?
