ARM & Leon3 processors in the same design

Hi all,

I am using the template design(leon3-digilent-xc7z020) for ZedBoard. Normally, this template instantiates a Leon3 in the programmable logic (FPGA) side of the device and connect the Leon3 to the ARM processor through the ahb2axi bridge.

I was able to create a bitfile and program the board.
Now, my goal is to test the communication between ARM and Leon3.

To do this, I want to know how to write a C program to test the transfer of data between the ARM CPU and the leon3 via DDR3 interface and the Bridge in the FPGA fabric.

Could you give me a C example or a link to help me.

Many thanks!

May be you could make a breakpoint in modelsim when u have a transaction b/n the processors. The other option is to moniter the amba bus and look at the values to say wether they are what u are looking for or not. About the c code, im working on a similar topic and have not reached that level yet. Good luck!

Hello!

You can use the leon3 in a zedboard (leon3-digilent-xc7z020)?

I need your help.
