We're trying to modify and existing FPGA program running on the FPGA portion of the Cyclone V to send data to the HPS portion of the Cyclone V, but cannot find any helpful documentation.
I am pretty new to the Cyclone V SoC, so my knowledge is limited on how this would be done. I'm guessing I need to use the FPGA-to-HPS bridge to write data to a memory buffer? Are there any examples out there for this process that do it with something other than LEDs?
You can refer to the datamover example:
it shows how to transfer data between FPGA and HPS. The design files were removed since it was using an older version of Linux Kernel. I am working on migrating the design to higher kernel. Once done, I will send you the design files.
Thanks for your reply. Do you have any time estimate on when the migration to the higher kernel will be completed?
Is it correct to say that with the info provided at the link, we would be able to use the design files as a sort of template to configure our own program to write data from the FPGA to HPS?
