    Hi,

    Thank you for your fast reply.

    I am not sure if a transfer on the same channel is in progress. The IPNC code only define the EDMA channel in the line 27 of the file vaLink_priv.h.

    However I find the use of EDMA in the function VaLink_algCopyFrames() in line 2388 of the file vaLink_alg.c.

    If it monopolize the EDMA source?

    Could you give me some suggestions for using the EDMA in IPNC code.
