Hi all
 we  have got into an issue with the EDMA3  in our project ,we are trying to do QDMA link transfers . we are popullating the required param contexts in an local array structure and transfering them to the EDMA PaRams using IDMA CHANNEL 0  the params are getting transferred but at times the qdma links are not being triggered and the transfer is not taking place. the QEER REGISTER  is showing as 0000000F as it should be and the
QCHMAP associated with the qdma channel is also showing mapping correctly to the PaRam to be mapped and the trigger word but the
transfer is failing i,e suppose there are 5 links. after 3rd link updation the transfer is not taking place and the links are not being updated  can any 1  plz suggest me what is that i am missing to make my EDMA3 work and the ways to debug this , the PaRams i am using are from 78to 81 and 84 to 100. at the time the transfer is getting struck QER and QSER are  showing as 00000001 .
