Usually, I use uart for my stm32 to communicate with my PC(ubuntu),

I set 115200 baudrate, and use a USB to TTL tool(PL2303HX

In PC, use the minicom to get data from stm32,


But now, I have to transmit much more data, I need more than 1Mbps speed,

I found some article say that stm32 can set to 2Mbps even 4Mbps,

I thought I can just set a more fast baudrate like, such as 1152000 for both PC and stm32,

but I found I cannot get correct data,


I have no idea where can I fix it?  is there any limit for uart?

Or is there any way for me to communicate for stm32 and PC with high transmit speed ?
