3.9 Change Kernel Console
If you want to use another UART port as the kernel console, you can follow the
steps below to adjust the configuration.
modify the file target/linux/ramips/dts/LINKIT7688.dts and chang
chosen {
bootargs = "console=ttyS2,57600";
};
to this (e.g. change to UART0 and 115200 baudrate):
chosen {
bootargs = "console=ttyS0,115200";
};
This will then change the kernel console from UART2 to UART0 and its
baudrate from 57600 to 115200.
Now build the firmware and upload it to the board through the Web UI or the
USB drive.
