Errors building Clocked Video Output

Hi formjk,

Thanks for following up. The compile errors must be some weird artifact in one of my projects. I can successfully hook up an SGDMA to a Clocked Video Out with or without a framebuffer in between and build the whole thing in a separate new project.

I'm now studying the Avalon ST Video spec to figure out whether I really need a custom component or not. It seems that the signals are all there and it's a matter of sequencing and formatting the data correctly.

As to the framebuffer - I was hoping to just go straight from the SGDMA to the video out but you mention that it might not work due to throughput. Does the framebuffer have a faster way to master its way to the memory than the SGDMA? In that case, do I still need the SGDMA or can I just have the CPU fill the memory at the base address set up for the frame buffer?

Thanks,

Andrew
