Building HAOS image with Serial Port Support

Development
1

Hello all,

I have been trying to install Home Assistant OS on my APU.3C4-based PC (PC Engines apu3c4 product file). Note the board has no graphics card port. I managed to write the downloaded 8.4 release image to its disk. I would like to use its serial port so I can control the machine from my laptop, but I am not getting anything on the port that is connected to my laptop running Debian GNU/Linux (the stable Bullseye release). Because of that, I don’t know what is going on when I boot from SSD that has the image written over it.

How do I make HAOS to give something on the serial port? I believe I should change the kernel arguments to include console=ttyS0,115200n8 as that has worked for other OSes I installed on the machine. However, I do not know how to do that with the officially released 8.4 image.

What I attempted is to build a generic_x86_64 HAOS image by cloning https://github.com/home-assistant/operating-system/, checking out the 8.4 tag, then modifying ./buildroot-external/board/pc/generic-x86-64/cmdline.txt to read console=ttyS0,115200n8, and finally running sudo scripts/enter.sh make generic_x86_64. Unfortunately, this results in the following error:

...

What do I do to resolve this image build issue, or more generally - how to get the serial port working for HAOS?

Hi @mdimjasevic ,

can’t help you with the error directly. But I want to do the same. I think we have to add serial console support in kernel as well:

I’ve changed the kernel config: buildroot-external/board/pc/generic-x86-64/kernel.config

...
CONFIG_USB_SERIAL_CONSOLE=y
CONFIG_SERIAL_CONSOLE=y
...

Then I’ve run scripts/enter.sh make generic_x86_64-config and afterwards scripts/enter.sh make generic_x86_64. Now it’s compiling for an hour already.

This didn’t work for me. I think there has to be modified more for the apu.

Hi all:

I had the same problem (my system is Debian 11 64bit in Virtual Box).

Reference: Getting Started with Home Assistant Operating System Development | Home Assistant Developer Docs, to Build ova.

do: “sudo scripts/enter.sh make O=output_ova ova” failed, console information:

for image in $(ls -S /build/images/*.tar); do
	docker load --input "${image}"
done
...

then check directory “/build/images/*.tar”, tar files exists.

I have no idea about this program, Hope for help.
