Subject: How to enable output to serial console at run-time?
Date: Thu, 2 Nov 2017 16:39:36 +0100 [thread overview]
Message-ID: <3c348fe1-1474-6c19-691d-8130d4bd0d32@molgen.mpg.de> (raw)
Dear Linux folks,
If I want to output the Linux kernel messages to the serial console, but
the `console=ttyS…` line is missing on the Linux command line, is there
a way to activate that during run-time by, for example, using the sysfs
interface?
Kind regards,
Paul
