Hello all, I am trying to stream data from a Custom IP, right now it's just a counter running at 8MHz, to a FIFO, to DMA. This is an image of the design. But the DMA and FIFO only ask (TREADY/WREADY) for data about 0.2 MHz. I'm sure it's because my code is only getting 4 bytes at a time from DMA, so even in a simple loop it's not fast enough. My question is hopefully an easy one: with something like XAxiDma_SimpleTransfer(&AxiDma,(u32) RxBufferPtr, MAX_PKT_LEN, XAXIDMA_DEVICE_TO_DMA); I should be able to have an array of size MAX_PKT_LEN ready to use (I'm just trying to
