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,
