I have an issue which I really cannot understand. I have a traffic generator connected to a AXI Stream Data FIFO which is connected to a AXI DMA. AXI DMA is connected via the interconnect to the HP port. I am reading the data in the Data FIFO by connected its data_read line to my custom IP which just reads the data. The problem is that the amount of data transferred is not correct with every transaction. The traf_gen sends data in 16 data bursts, and whatever length I give in simple_dma_transfer() function, the data copied is always 16. I am not sure why is that.
