Hi,

The design is working fine without any problems. I am having problems in running the DMA transfer (read and write) to the board and back.

Could you please share some steps how we can debug this issue. I tried understanding the Linux code and making some changes but nothing works.

As soon as I "Start DMA" by entering '1' and 'Enter' the application and the Linux OS stops responding.

Similarly in Windows when I click on start I get a PCie error shown in the figures attached above.

Thanks!

Regards,
