CCS/TCI6638K2K: Can EDMA be used in SWI code

Hi All,

 I have a problem with edma used in SWI code.

 I need to reduce time in UE code so i am using EDMA . When I use edma in task code,it works fine. i am using Edma at three places for continuous buffer transfer in SWI code. Edma configurations are

Edma_CC =1 ,DMA Channel = 1, PaRAM =1 , Manual Trigger and source DDR memory & destination  L2SRAM. if i use Edma in code i am facing issue with UE attach and attach is not consistent.

-> one Edma data copy working but not consistence.

->  another two places, Edma creating issue.

But for every transfer i am checking TPCC_IPR register and it shows data transfer completed.and EMR register is zeros.

when Edma use in SWI code, is there any dependency?

Hope for your reply,

Thanks,
