发送文件“字库图片取模工具使用说明.pdf”，由于分包的原因，最后一个包长度不足补0了，接收到文件比较结果一致，重命名为pdf可以正常打开

Was this test on one IC (two channels) or two (one channel per IC) ?

What was the time taken to send 10MB ?

AI8H8K64U, AI8H2K12U, 2IC
Any time taken (seconds) numbers for
AI8H8K64U => AI8H2K12U
and
AI8H2K12U => AI8H8K64U ?
It seems the UART-DMA that is available in the AI8H8K64U should allow faster sustained baud data rates, than AI8H2K12U I would be curious to know AI8H8K64U(DMA) => FT2232H ? Average Data rate possible at 8MBd & 6MBd ? and FT2232H => AI8H8K64U(DMA) ? What Baud Rates does it drop characters ?

使用官方固件测试，不开源，不清楚是否使用了DMA

没使用 DMA, 应为有些有 DMA, 有些没 DMA
