Using the amba bus on arm (embedded)

Former Member
Former Member over 10 years ago

Hello,

I ran the linux from the Zedboard itself, and there I'm writing code c for example to get data from the Ethernet.

Now I want to send this data I have got to the amba bus (in order to process this data in Vivado. I meant I want to send this data to the amba bus and to get it from the amba bus in Vivado(in Fpga).
My question is how do I do this in c?
How I send this data to the amba? Is there any library to work with the bus which have the function, for example : senddata(data) and ect.

Thank you very much.

    Hi,

    When you create an AXI Lite connection in a hardware peripheral and connect it to the ARM processor through the GP ports it automatically assigns an address range to your peripheral.  If you are in standalone mode you can write directly to this address to write to your peripheral.  The ZynqGeek blog post on this is very old now, but it covers some of the basics which may be useful:
