I have a BananaPi M3 device and I am trying to read from UART port some data coming with 4Mb baudrate. I have a harware connected to the UART that generated data with 4Mb baudrate. I made a short script in Python to read the data, but if I set up 4Mb as baudrate I don;t get anything, not even scrambled information. On lower baudrates like 115200 I get scrambled data.
The question is, how to determine what is the maximum baudrate that BananaPi supports on UART port OR how to increate it to support 4Mb baudrate?
Thank you
