Hi everyone! Please help me.. i have a project with a custom axi slave design that implements multiple memory ranges 256 words each . A master ( my processor in figure) can write burst data to the example slave and read the data back. The problem is that i don't find the API or the instructions to program the ARM processor inside the zynq 7000 to work in burst mode!
Can someone help me??
thanks!!
Best regards!
As far as I remember from my past (short) experience with Zynq systems, one way to do this is using the DMA engine included in the PS. You should be able to program the DMA specifying burst size, length, dst address and so on.
Do you remember in particular what should i do ?
I don't recall precisely which Xilinx APIs I used, but the C code linked at this code should help you out:
