DE0-Nano-SoC and VIP Frame Buffer II application

Hi Mats Bjorkvist,

Good Day.

Apologize for the delayed response.

I believe this could possibly due to the Go bit gets deasserted by default when enable run-time control.

You may refer to chapter 16.7. Frame Buffer Control Registers of the Video and Image Processing Suite User Guide that states " Setting this bit to 0 causes the IP core to stop the next time control information is read. When you enable run-time control, the Go bit gets deasserted by default. If you do not enable run-time control, the Go is asserted by default. "

Thank you for your patience.
