Hi everybody
Can anybody tell what is the correct way to check wheather "Transfer Count" in
an EDMA has reached zero. I am using DSK TMS320C6713. I am transfering values
from "gBufRcv[32]" to "gBufXmt[32]" using EDMA. I know when transfer completes,
".cnt" field should go to zero but I dont know what is the proper way to check.
Any help is very much appreciated.
Kind Regards

Dear Anser,
the only correct way to check if a EDMA transfer is complete is using a
TCINT interrupt. You can either use an interrupt routine, or poll the CIPR.

Hi,
you can refer the memory map registers. fetch the value ofrespective address and extract the particular number of bit and check are they zero or not. otherwise u can use CSL APIs where u can directly use macros to fetch the paticular part of register and check it.
