I’m installing Ubuntu 22.04 and it installs and runs fine. The only problem is that the boot process is not shown on the screen. This can be worked around by add console=tty0
to the command line. This uses the framebuffer I believe.
By default, I think the kernel reads bootarg
from the device tree and outputs the boot process via UART to one of the serial ports. However, I can’t see any output using Serial over LAN of the BMC.
So my questions are:
- Which
/dev/tty*
is the Serial over LAN port mapped to when the system is fully boot? - Which parameters should be supplied to
console
orearlycon
so that the boot process can be monitored using Serial over LAN.
