[U-Boot-Users] switching serial console on or off

[Konstantin Kletschke]

Hi Folks!

Again I wonder if it is possible to switch off the serial console in
u-boot and only switching it on for debugging purposes so its free for
other applications in the daily work.

I wonder if it is possible to determine a level of a GPIO pin and set
(okay, this will work for sure) an env variable on that. This decides
wether the serial console is enabled or the linux kernel gets booted
silently. 

Is something like that possible?

Kind regards, Konsti
