Hi All,
I want to connect my Radxa Rock Pro board to another computer through serial port. The data communication is true when baud rate is less than 115200. When I set baud rate to 230400, 460800 or 921600 the communication fails and nothing transmit nor receive.
I have done my tests in both Linux and Android operating system, but the result was the same.
How can I resolve this problem?
In page number 1101 of the following datasheet, there is a table that shows how to config uart baud rate. But I do not know how to use it in user space of the Linux or Android?
