Sorry to reply late, I’ve seen this chapter about “Disable Console over UART”
But…I’m not try to improve the kernel boot time with remove UART.
My scenario is our product will try to design a Carrier Board. In our design so far, since we will use the UAR0/UART1 to design as Console.
But the UART2 will deign to connect with another Micro-Processor for communication.
But there is only the UART2[debug] will print the whole message since power-on( that indicate it will show the whole booting message which include cboot, Kernel…etc).
the UART1 print the message after kernel finish system initial and login.
We just want to confirm “Is that possible to configure the UART0/1 to act as the UART2(print message since power on)”
