您好，请教一下，我在尝试使用pp4fpgas-cn-hls/boards/Pynq-Z1/notebooks/00-Tutorial.ipynb中间huffuman编码的ip在block diagram上面连接的时候，碰到两个问题(critical warning)：

Interface connected to S_AXIS_S2MM does not have TLAST port 对于两个dma模块在validate时候都碰到这个问题，我在网上查了下似乎并没有非常统一的解决方案，请问这里是将TLAST连接到哪里的啊？
Bus Interface property TDATA_NUM_BYTES does not match between /huffman_0/symbol_histogram_value_V(2) and /axi_dma_1/M_AXIS_MM2S(4)
这个我试了下似乎可以用axi width converter解决，但是我看这个图片中间似乎并没有出现这个位数转换的问题，请问是不是有什么其他的设置需要注意的？
谢谢！
