Hi,

 

I have connected Orange Pi Lite over serial UART, but looks like the default settings are to not output the boot log to serial. You can only see U-Boot messages, then "Uncompressing Linux kernel" and after some time the login prompt comes.

 

What exactly do I need to change/configure to get the classic kernel boot log to serial console?

Increase loglevel, e.g. loglevel=9 for everything.

and also change "console=both" to "console=serial" ...
