  1. hello Yes i am using PS for doing this and i have POSIX support on linux just i want the interface of DDR to ethernet port. and i am planning to create two thread which can run simultaneously with shared memory and in one I will write the data into DDR and other will read the data from that and at the same time writing process is going on on another allocated buffer on DDR and so on.
  2. Thank you for your king reply, I mean by continuous is packet by packet. When one packet transferred another should start.
  3. Hello, I have completed cyclic DMA in scatter gather mode. In that data goes from PL to DDR of PS so now i want to transfer from DDR to network port continuously. when dma is transferring data in first buffer simultaneously data from second buffer have to send on network port and so on. thanking you,
  4. Thank you for your response. I am now successfully able to implement this scatter gather mode of DMA in linux. and now trying to transfer that data from DDR to host PC via network port can anybody help me to transfer continuous data ???? thanking you, princy
  5. Hello I have implemented DMA in simple register mode on linux i am using zedboard. i am attaching the source code file (dma_normal_final_29_12_counter_axis_test)for that. Now i want cyclic DMA in scatter gather mode please help me. I am taking reference of this above source code and PG021 document for AXI DMA IP but it give me error msg in ststus register and my data is not transmitting. for scatter gather mode i have made this (scatter_gather) type of code. please check it out and give me suggestion. please help me. thanking you, dma_normal_final_29_12_conter_axis_test.txt scatter_gather_dma.rtf
