Console stopped during installation (redirected to VGA?)

Hi everyone

I got a brand new Qotom Q20331G9 C3758R and tried to install OPNsense, but I noticed that the serial console stops at EFI framebuffer information. I tested the serial and VGA installer with the same result. The system has VGA as well as a Console port.

If I connect to the serial com port with PuTTY, the console stops working with the following output:

I also tried to hit 3 on the boot menu and set the following variables, but with the same result:
set boot_multicons=YES
set boot_serial=YES
set comconsole_speed=115200
set console=comconsole
boot


The available consoles are efi, comconsole, nullconsole, spinconsole

After a few minutes, I can connect over the WebUI on the LAN port with 192.168.1.1. I also tried to set the primary console to the serial console under System Settings Administration and deactivated the virtual terminal driver. But also, with this setting, the PuTTY console doesn't respond.


I am new in the Linux/FreeBSD world and have no clue about the bootloaders. The boot continues and, I guess, is redirected to the VGA. Still, I currently don't have a VGA Cable and Adapter to HDMI available. Did I miss a setting in the BIOS or during the installation to have the console continue on the Console port?

have you checked you BIOS settings? Usually it's named something like "console redicrection" or similar

Thanks for your reply.

In the BIOS under Serial Port Console Redirection is the following set:
COM0 (Pci Bus0,Dev26,Func0)
Console Redirection [Enabled]

Then, there are multiple options for Console Redirection Settings and Legacy Console Redirection Settings.

Furthermore, under Serial Port for Out-of-Band Management/Windows Emergency Management Services (EMS) is the Console Redirection [Disabled]

However, that's the BIOS Console Redirection, the way I can currently select the boot device, right? If I turn off the COM0 redirection, do I retain the possibility of entering the BIOS via the USB Console connection?

I also get to the installer's splash screen on the console and can select everything there. But after that, it stops with the EFI framebuffer information.

Hi everyone

So, after testing a lot, I got it to a point where it is passing the EFI framebuffer information.
Quite a noobie mistake. I had to set the port speed to 115200 in the Windows Device Manager as well as in PuTTY and I only had it configured in PuTTY.

However, now I am stuck at Mounting filesys. What could be my mistake?

Dual Console: Serial Primary, Video Secondary
Mounting filesys


none I can see. CAM errors are related to storage. Either controller, cable or disk. A problem on one or more.

Hi there, make sure that the image you are loading has serial console enabled.


Hi there, thanks for all your help!

I used the serial installer but also organised a VGA cable in the meantime. Interestingly, the VGA installer gets through, and I could install OPNsense but have yet to get the console running even if I configure the console under System > Settings > Administration. I wonder why I can install OPNsense via VGA but not via serial console, and it stops after initialising the two consoles with:

...
Dual Console: Serial Primary, Video Secondary
Mounting filesys


I must have done something wrong, but I have less knowledge of FreeBSD/Linux to debug the setup. Maybe it also has to do with the China hardware and I should just accept it as it is... however, I like to tinker and solve such problems to get the full potential and everything running as it should ;)

Could it maybe also have something to do with boot configuration, perhaps something along this:

OK set boot_multicons="YES"            #What this does is allow multiple consoles. IE. Screen and Serial Port
OK set boot_serial="YES"               #This is the only line needed. This is the trigger
OK set comconsole_speed="115200"       #This setting is actually the default so it is not needed in most cases
OK set console="comconsole,efi"        #This sets the multi console interfaces for EFI BIOS

Or even redirecting the UART configuration?

OK set hw.uart.console="mm:0xfedc9000,rs:2"

Hi everyone!

So I have tested more and discovered the console only works on the eficonsole. However, I am still stuck on the same stage: "Mounting filesys" while on the VGA port on the same boot it outputs at this stage "Mounting filesystem" and continues booting without issue.

I noticed grey and white outputs on the VGA Port, and the console connected with PuTTY only spits out those lines written in white but not grey.

Maybe this helps to find my misconfiguration?

you should not need to modify these boot options to get a working console via VGA unless using serial or embedded images. Maybe you should also consult the vendor.

The VGA console is working perfectly fine, I try to get the com console working over RJ45 -> USB, therefore the EIF Console.

Right ok. All those values you have been fiddling with will only apply to the primary console. This is why I say you don't need them.
If you want to ALSO have a secondary console, you need to go back to System | Settings | Administration and try the different values in "Secondary Console".
Looking at the log:
Dual Console: Serial Primary, Video Secondary
Mounting filesys

The last message is Mounting filesys but probably was the last before the buffer was directed by the line above to the both consoles. As to what value it should be is a question for the vendor if you can't figure it out by trial and error.
p.s. my guess is it would need to be either VGA or serial for common setups.

I'm currently in the same situation as @nydidric, same hardware. I did manage to get beyond "EFI framebuffer" with

set comconsole_port=0xe060

and only serial enabled. Dual console didn't work. With serial and VGA connected (yes, VGA is working even it's set to boot only serial console) I get slightly different output. The serial stops at "Mounting filesys", but VGA also stops. Unfortunately I forgot to make a note on the last line and will post it later today.

I'll report back after some more tests and I hope we will figure it out.

Perhaps I found something. I took the information from the device
uart2: <Intel Denverton UART> port 0xe060-0xe067 mem 0xdf519000-0xdf5190ff irq 16 at device 26.0 on pci0

On boot I pressed "5" to get "Dual (Video primary)" (because everything else is not working) and then "3":

set hint.uart.0.flags=0x00
set hint.uart.1.flags=0x00
set hint.uart.2.flags=0x10
set hint.uart.2.at="pci"
set hint.uart.2.port="0xe060"
set hint.uart.2.irq="16"


It's booting with VGA and console output, but:
On the VGA output I can see every message (white and some grey) and login after boot. On the serial output all grey messages, e. g. >> Invoking start script 'newwanip' are missing and I can't login after boot.

Is anyone with more experience able to solve this?

I tried many different combinations and I can't get it to work 100%. Why is it, that I can't get some output to the comconsole? What am I missing?

It's now booting with efi (had an error, that vidconsole doesn't exist) and comconsole, but it misses those ">> Invoking ..." lines completely on the console output. :o

Can you install, though? What happens once you explicitly enable the serial console in the UI?
