cvxx 3 Posted August 10, 2020 Share Posted August 10, 2020 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?
