LogiCORE IP Video Scaler v7.01.a - Why are the Horizontal Shrink Factor (HSF) and the Vertical Shrink Factor (VSF) registers zero when the AXI4-Lite interface is selected?

Description

Why are the Horizontal Shrink Factor (HSF) and the Vertical Shrink Factor (VSF) registers zero when the AXI4-Lite interface is selected?

Solution

This is a known issue that affects the Video Scaler v7.00.a and v7.01.a.

This can be worked around by updating the Horizontal Shrink Factor (HSF - 0x100)and the Vertical Shrink Factor (VSF 0x104) registers using the AXI4-Lite interface,after the core is released from reset.
