SDMA access in A7 and M4 cores of the imx7s

Hi All,


I need to use SDMA on imx7s SoC for both cores Cortex A7 and Cortex M4.


- I think I need to use RDC on M4 to access this peripheral. I have question about Linux on A7, does current FreeScale Linux repository have RDC used for SDMA?


- SDMA generate interrupt when any script execution is completed. Does this interrupt received by both cores?

I need to access SAI1 from M4 and SAI2 from A7 through SDMA. Is it possible?


Best Regards,
