How to write data into DDR3 SDRAM-HPS!

Hi everyone! I create Qsys to connect SDRAM/FPGA that saves data of camera with HPS. I will read this data by arm through H2F AXI Bridge and send it to VGA. I use 2 components: "Frame Reader" and ...

It is definitely possible. However, you need to use the HPS-FPGA axi bus and not the lightweight axi bus for higher data throughput.

Hi WH2011!

I think I will use 3 bridges:

+ Lightweight axi: this only use to control Frame Reader

+ HPS-FPGA Bridge: I will use this bridge to read data from DDR3-FPGA to save to DDR3-HPS

+ FPGA-HPS Bridge: Frame Reader will be connected with this bridge to read data from DDR3-HPS and output to VGA

Now, I am doing this project, but I have a problem when using arm to read data from DDR3-FPGA and Frame Reader read data from DDR3-HPS and output to VGA.

Do you give me a direction for me

Sorry if I disturb you!
