Attempting to build with ubuntu 24.04

Hello, it’s been a while since posting, (2022 by the looks of it), my clear-fog base has been running along nicely since my 2022 build. but I’d like to upgrade it to upgrade to noble 24.04 - i know it’s not supported yet by solidrun. I’ll happily contribute back when i’ve built.

I’ve trying to build against develop-SDK12 and develop-SDK12-mainline trees.

My current attempt, fails after writing the ubuntu filesystem. (that seems to complete).

Creating journal (8192 blocks): done
Copying files into the device: done
Writing superblocks and filesystem accounting information: done

There is discussion of a very similar looking issue caused by a bug but i think it might going down a rabbit hole after reading into to it.

I’m using docker build env.

Any pointers to look into would be greatly appreciated.
[edit] As i’m reading it may be related to the bug in qemu-system-aarch64
Kind regards

[UPDATE]

Seems like it was related to the, or a related, bug in qemu-system-aarch64. I’ve compiled the most recent version from https://gitlab.com/qemu-project/qemu master.

QEMU emulator version 9.2.50 (v9.2.0-945-ge8aa7fdcdd).

previous version was what ever was used in docker. it also occured on qemu-8.2.2 from noble apt respository.

I’m continuing with the build at least.

as a bit of an update to this. I managed to successfully build ub24.04 with kernel6.13-rc7. I had to hack the musdk/modules/cma and pp2 code to get it to compile.

however, eth1 link will not come up, it’s succesfully loaded in PHY/SGMII link mode. i’m not sure if it’s related to my above hack to get it to compile. But i wanted to try a pre-built image to compare.
