Hi Lars,

Thanks for the reply. I have created fft IP using AXI-DMA for data transfer. But I am planning to use AXI-DMA using UIO. For this, I have to give physical address of the buffer to DMA. I have no idea how to convert virtual address to physical or how I will get physical address of the buffer. I have searched but failed to find complete example of the same. If you have any idea, please help me.

 

Thanks & Regards,

Atma
