AXI Video Direct Memory Access (VDMA) - Release Notes and Known Issues

This Release Note and Known Issues Answer Record is for the AXI VDMA and contains the following information:

For installation instructions, general CORE Generator known issues, and design tools requirements, see the IP Release Notes Guide (XTP025).

General Information

New Features

Description	Core Version
Resource optimization	5.04.a
Default value of C_MM2S_SOF_ENABLE and C_S2MM_SOF_ENABLE changed from 0 to 1	5.03.a
Improved behavior during frame size and line size mismatch errors with separate status bits for SOF_EARLY, SOF_LATE, EOL_EARLY, and EOL_LATE errors on the S2MM channel	5.02.a
S2MM channel will never halt on line size mismatch errors in all modes including non-flush and free-run mode	5.02.a
MM2S will output Start-of-Frame on TUSER(0) in all modes including free-run mode	5.02.a
Added two new GenLock modes called Dynamic GenLock Master and Dynamic GenLock Slave	5.01.a
Integer byte data width support on streaming interface of MM2S and S2MM channel	5.01.a
External frame sync and flush enable/disable made independent for both channels by enhancing C_USE_FSYNC and C_FLUSH_ON_FSYNC parameter definitions (maintaining full backward compatibility)	5.01.a

Resolved Issues

Description	Core Version
Genlock Source bit in control register not set by driver (Xilinx Answer 53331)	5.04.a
Incorrect addressing after size mismatch error (Xilinx Answer 52479)	5.03.a
Incorrect TIG propagation in EDK (Xilinx Answer 46044)	5.01.a
