2013.4 AXI DMA: Is a TLAST signal required with an S_AXIS_S2MM interface?

Description

Is a TLAST signal required for an AXI DMA controller?

Solution

Yes. The TLAST signal is used to identify end-of-packet on the incoming stream of data hence it is a requirement for axi_dma on the S_AXIS_S2MM.

This signal must be connected to guarantee correct functionality.
