TI DM3730 changes debuging serial port when linux starts

Hi Feihu,

The console port can be configured via bootargs environment variable in the u-boot. You should check the value of the console in the bootargs. If you are using console on the serial port 3 you should have configured something like this:

console=ttyS3,115200n8     but this should be check by printenv command executed in the u-boot prompt.

You must change ttyS3 to ttyS0.

You can find some useful descriptions and examples in the following articles:

Hi Cvetolin,

Thanks very much for your prompt reply. What you guide can change the serial port which is used to print information and debug the linux kernal.

However, by searching in the Internet, i know DM3730's bootloader involves the Xloader and Uboot  which both use the serial port,  so i should change

their codes. What's more, the serial port is also be used in the filesystem to print information. But  as a newer, i cannot do this step by step.

Thanks again and BR.
