Because Linux raw SDK, a serial port in accordance with the resistance by the peripheral bus frequency set too low, lead to higher baud rate, I want to use a serial port driver doesn't support the

Now I put the CLK source code about the frequency of the peripherals increased (modified clock source frequency coefficient), to burn the kernel,

Restart, in print information, see the uboot phase (115000) print information is normal, when to enter "Starting the kernel... ", behind the print the code, that change the clock may play a role?

I want to ask, after into the kernel, consel serial port is artificial to initialize? How to do?

CodePudding user response:

After the statement, think not interact through putty, so urgent to get the print information is normal

I remember when it starts to add a parameter to change the kernel using the baud rate of the console=ttyS0, 115200
