I am trying to communicate my drone FCU to TX2 through UART2 (Auvidea J130) or UART1 (Developer Kit). Now it works on Developer Kit @115200 and @230400 (baud rate), while we need it to work @921600.
It says in TRM that there are two UART mode 16450 (default) and 16550. It seems there is no FIFO in 16450 mode. I want to know how to change the default 16450 mode to 16550 mode?
