How to disable console late?

How to disable console late?

[Holger Schurig]

On my i.MX6 I have CONFIG_CONSOLE_FULL and CONSOLE_ACTIVATE_NONE
defined. But still my serial is automatically activated as a console.

barebox:/ devinfo cs0
Bus: platform
Parameters:
  baudrate: 115200
  active: ioe

I'd rather active the serial port as a console only if a key is
pressed during power on. Based on the help text of
CONFIG_ACTIVATE_NONE, I actually thought that this would happen.

Any hints?


I could remove chosen/stdout-path from my DTS and put it in
on-the-fly? This sounds a bit ugly ...

Indeed you have to remove the stdout-path property from DTS. You don't
have to add it back, 'cs0.active=ioe' should do it. Note we currently
don't have persistent names for the console devices which means that
cs0 is whatever is probed first.

I need to check in my local tree but I’ve done this for input not output

For the secure boot support
