Dear all,
I have this strange baudrate issue in the product using i.MX8QM with Android 9.
ttyLP3 (UART3) default baudrate is 9600.
I run stty command setting it to 19200.
/ # stty -F /dev/ttyLP3
speed 19200 baud; line = 28;
However, the baudrate on uart bus measured from oscilloscope is only 5760 (please check the attachment below).
Please try to test other baudrate using oscilloscope
