I believe you need to change console to ttyS0 with v4.14.x.
Yes that solved it (see the bottom part of my earlier mail :-)), but was
unexpected, as in the past the console used by the iLO MP of the rp3440
was always ttyS1.
Possibly, console argument is no longer needed
on command line.
I believe it is needed to configure the console in any case. Without
"console=" argument palo will add what is configured the default for a
1. HP machines can use either a serial or a graphics boot console.
Palo now figures out which one you are using and adds the
appropriate "console=" to the end of the boot command line. It is
only added if you don't already have "console=" in your boot
...(e.g. ttyS1 for rp3440 since ) and if you manually delete the
console argument when interacting with IPL to really get rid of it, the
console output stops after the kernel disables ttyB0:
[ 0.001572] Console: colour dummy device 160x64
[ 0.002947] console [tty0] enabled
[ 0.003082] bootconsole [ttyB0] disabled
But interestingly the machine this time continued to boot and was
reachable via network later on.
You can probably access system via network after boot completes.
No, as mentioned earlier that didn't work out when the console was
configured to ttyS1 by palo. I waited several minutes and the machine
was not accessible via network in this case.
Not sure if console output on a serial port of an rp3440 or related
machines needs to be "consumed" by a terminal to continue. But I've seen
something similar on my rp2470 (with GSP), where I needed to hit the
enter key multiple times to continue the boot process, each time another
few messages would appear on my terminal, but no output and no progress
if I I didn't hit the enter key. Systemd was already running at this
time. Strange behaviour.
Make sure palo 1.99 is installed and you have run palo at least once to update palo config on disk.
Palo 1.99 is installed.
