I am attempting to issue a soft reset to the Video Scaler via the AXI Lite Interface. However, the core appears to still be outputting video and does not seem to reset properly at all.
The software reset is bit 31 of the Control register located at 0x0000.
This is a known issue that the software reset in the Video Scaler v7.00.a, v7.01.a and v8.0 only resets the AXI4-Lite Interface.
This issue has been resolved in the Video Scaler v7.01.a Rev2 patch for ISE Design Suite and EDK tools.
This issue has been resolved in the Video Scaler v8.1 for the Vivado tools.
To perform a proper full reset of the core, you must drive core_aresetn Low.
