I'm doing a project with this device: 'xc7z010clg400-1'. The objective is to write into a RAM by ARM. I've already did the VHDL part into Vivado with the processing system, bram controller and the rest of the components. Now I have to program the microprocessor in the Vivado SDK with c language. But I've never used it and I don´t know how it works. Could you please give me an example of how to program a RAM in this case?
Thank you in advantaged :)

I want to write an image into the RAM by the ARM and display it into a screen, I've already program how to display it in the screen, but I don´t know how to write it into the RAM of my design.

Yes I've already implement a VGA_driver like in the photo and also I have the processing system, bram controller and everything. Now I have to program the microcontroller into Vivado SDK to write into the RAM.
Thank you in advance. :)

What resolution do you want to output via analog RGB ?
I'm sure that you need to implement DRAM controller (ex. MIG) as frame buffer except VGA (640x480).
Because of internal BRAM is not enough memory as frame buffer.
