Interfacing SGDMA with custom component

I am using the "using triple speed Ethernet" with DE2-115 board tutorial, and trying to connect my own component directly to SGDMA using Q-sys.

SGDMA is operating in stream to memory mode and my component is connected as a memory mapped slave to the m_write interface of the SGDMA.

My component successfully receives data but there is a problem with synchronization; the "write" signal of the "m_write" interface is not being asserted with write operation.

When I connect the same component to the nios2 data master as a memory mapped slave and write to its address It works perfectly fine.

I have tried to find a timing diagram for the SGDMA to understand how the m_write interface works but could not find it.

Thank you a lot
