TS201S EZ-KIT VDK ISR

Hi
           
Is any body is having idea how to can interrupts in VDK for using LinkPort  DMA.
I did test data communication using DMA in the LinkPorts,

referenced by example code "Producer_Consumer_MP" except for Multicore process & message.

when I sarted this code it did not enter the ISR function and driver open funtion.

I don't know What is problem.


with regards,

Nathan

    Hi Nathan,

              Sorry for the delay in getting back on this. I have not tested the link port DMA codes using VDK based application any time. I have gone through your application code and it looks o.k. I will try to test this code on the EZ-KIT and see what happens.

    Mean time I will give you some suggestions to debug the problem from Link port point of view:

    1. Can you check for the Link port register values after running the code? Have the DMA started?

    2. Do you see any data words in the transmit/receive buffers?

    3. Are there any error conditions set?

    4. If possible probe the link port signals as well.

    Best Regards,

    Jeyanthi
