Hello, Is it possible to set the speed of the UART3 to 921600 baud instead of 115000? How to do it? I need to connect to an arduino at that speed. I have tried with minicom but I can't get it. I have also tried to put the following command dtoverlay=miniuart-bt in /boot/armbianEnv.tx but it doesn't work either. to 115000 if I can connect well, therefore the port works correctly Is there any way?
