Other Parts Discussed in Thread: TMS320C6457

Hello,

Device used : TMS320C6457
IDE : CCS v5.2

I have problem with EDMA3 Chain bit.

Chain bit in edma3 option register is getting set of its own for one perticular channel.

I tried to reset is in code forcefully.

But it's not getting reset.

but if i'm trying to reset it using emulator(debugger) then it's getting reset.
what could be the issue??

Thanks.

    Hi,

    Thanks for your post.

    I would suggest taking a look at Section 2.8 of the C645x EDMA UG below:

    http://www.ti.com/lit/ug/spru966c/spru966c.pdf

    Also, I believe, there is a edma chain example from C6455 CSL package and may be, you could download the same and try build & execute the project at the below project location:

    ~\csl_c6455\example\edma\edma_chain_example

    Thanks & regards,

    Sivaraj K
