UART console line width limited to ~70 characters

[mdrmdr]

Hi,

 

I'm using Armbian 24.11.1 bookworm with a V6.6.62 64 bit Kernel on a NanoPi Neo2.

To debug, I have a UART/Serial-to-USB connector attached. Other end is on a Windows 11 box where I use Putty.

 

The setup works fine with one minor issue. During the print of the boot messages, suddenly the printed line width of lines with [ <status> ] is limited 70 columns.

It starts shortly after the Welcome to Armbian 24.11.1 bookworm! message and a "…" character is used to shorten the lines.

 

This part has normal line length:

Welcome to Armbian 24.11.1 bookworm!

[    4.922261] systemd[1]: Hostname set to <nanopineo>.
[    5.680204] systemd[1]: Binding to IPv6 address not available since kernel does not support IPv6.
[    5.689209] systemd[1]: Binding to IPv6 address not available since kernel does not support IPv6.
[    6.078395] systemd[1]: Queued start job for default target graphical.target.
[    6.107963] systemd[1]: Created slice system-getty.slice - Slice /system/getty.
[  OK  ] Created slice system-getty.slice - Slice /system/getty.
[    6.137033] systemd[1]: Created slice system-modprobe.slice - Slice /system/modprobe.

 

From the next output line on, most lines with [  OK  ] are shortened with "…":

[  OK  ] Created slice system-modpr…lice - Slice /system/modprobe.
[    6.165124] systemd[1]: Created slice system-serial\x2dgetty.slice - Slice /system/serial-getty.
[  OK  ] Created slice system-seria… - Slice /system/serial-getty.
[    6.191931] systemd[1]: Created slice user.slice - User and Session Slice.
[  OK  ] Created slice user.slice - User and Session Slice.
[    6.218740] systemd[1]: Started systemd-ask-password-console.path - Dispatch Password Requests to Console Directory Watch.
[  OK  ] Started systemd-ask-passwo…quests to Console Directory Watch.

 

What setting avoids this and allows the print of the full line with line wrap if too long?

I'd be already happy it it would be the same behavior as after login, where the line width as defined in Putty (120 characters) is used.

Is this just a general limitation of a UART console?
