Hi,
What is the maximum baudrate which can be achieved in UART on an imx8mp processor which is running Linux? I read in the MRM that up to 4.8Mbps can be achieved with increasing the module clock settings.
Has it been tried in Linux? If so, what changes would I have to make ? (device tree, defconfig etc)
If that baud rate is not achievable, what is the highest which can be achieved?
Thanks
Regards
Hello,
As said here:

UART baudrate depende upon module clock of UART.
module_clock frequency must always be greater or equal to 16x the maximum baud rate.
You may refer to the same thread for device tree configuration.
