Hi everybody.

 

I'm newbie in uClinux.

 

I have a BF533-EZ-Kit, without EZ-LAN module.

 

I send/receiver file to/from Host PC in 57600bps. Sometimes It take much time.

 

I want to  build my kernel that have default baud rate is 115200.

 

I've just look at menuconfig but can not find anything about baurate.

 

Can anyone help me??

 

Thankss

Message: 53323    review linux-2.6.x/Documentation/kernel-parameters.txt (the console= option) ... you control the serial console baud rate dynamically via the kernel command line

Message: 53327    uhh, no ... you should never modify the kernel sources like that.

 

the default settings in the serial driver are only the default.  if you set your console argument properly, the kernel will use 115200 baud.

 

the default u-boot command line also includes examples for how to set your console.
