WebThe AXI4-Stream FIFO doesn’t correctly set the TKEEP bits to null out the padding of the final beat. I definitely set the precise length of the packet in the TLR, though the GEM is definitely NOT clearing any WSTRB bits on the AXI-MM side. It’s a pretty minor problem all told, since ultimately the goal is to parse IP packets in PL, which ...
