Hi,

I don't believe its a compilation failure, as the counter + FIFO + DMA transfer design are compiling without any error. I would like to report that now I am not getting the API failure that I mentioned before. I could resolve that by the driver re-installation.

But I still not able to get the counter data (at the DDR4) that I am creating in the counter. A video of output is attached. the data I am expecting at the DDR4 is the counter output that counts from 0. It would be great if you could have a look to see what can cause this. If needed I can give access to my working directory to you.

Thank you.
