I would like my startup script to cat messages to ttyS1, as well as to 
the console (ttyS0). Basically for the purpose of informing users that 
the firmware cannot execute for some reason (we don't like to give 
access to the console). I was trying to avoid including stty or 
setserial, but if this is the accepted way to configure the serial port 
it's not a big deal ;-)

Interesting...I also tried manually entering a value here, but it 
didn't seem to have any effect. Maybe it just isn't used?

Thanks for your response!

[U-Boot] Question about baud rate

2011-11-14 Thread djantzen
Hi,

I'm using a board similar to canyonlands with a ppc460ex. The baud rate 
for ttyS0 is set to 115200 by the console= bootarg, but I'd also like to 
set ttyS1-3 to 115200 also.

For each of the three uarts, the device tree has the following line:

current-speed = <0>; /* Filled in by U-Boot */

How do I go about configuring u-boot to fill these with the baud rate I 
choose?

Sorry for the silly question!

Thanks,
Dan
