The importconfig was the missing piece, and now it worked. Thanks a lot for your help.
uEnv.txt is not created by image-script as it is initially empty (using my u-boot builtin environment). uEnv.txt allows to override this but it has to be created.
Ah, ok, so, I can create one and override settings, thanks.
How do we list the u-boot builtin environment from Linux? Would you be able to give an example of what to put in uEnv.txt in order to insert some customer linux boot link parameters? For example, i wish to experiment with the āclk_ignore_unusedā kernel parameter.
in uboot itself you can use printenv, in linux there is a tool named fw_printenv, but i have tried it yet. else you can cat /boot/uEnv.txt if there is any (your own content), else builtin environment is created by the uEnv_*.txt in my uboot-repo
for r3 and the bootargs you can extend bootopts
which is added to bootargs by buildargs
so try to add this to your /boot/uEnv.txt
bootopts=$bootopts clk_ignore_unused=1
Hello. Hello. I am trying to defend the Access Point at the 5GHz Radio wlan1 at Ubuntu. If I start radio /usr/sbin/hostapd /etc/hostapd/hostapd_wlan1.conf Errors will come back:
/usr/sbin/hostapd /etc/hostapd/hostapd_wlan1.conf

I use default settings /etc/hostapd/hostapd_wlan1.con from Ubuntu Image. How to fix this?
I guess this depends on your country settings.

See iw reg get/set
It is strange. I have tried Debian Bookworm image with 5 GHz radio. The radio works fine there. I used the wlan1 config file from Debian in Ubuntu and in Ubuntu the radio returns errors.
Afair ubuntu the regdomain handling was a bit differentā¦i remember about issues setting them. What does iw reg get says and what about the log?

Yeah,so domain unsetā¦there are multiple ways to set it and some donnot work in ubuntu

Have you installed the regdomain package?
iirc the cfg80211 way was working (and manual iw reg set),but of course needs the regulatory.db
I tried iw reg set CZ but iw reg get still returns:

Have you installed the regdomain package?
Sorry, but I donāt know how to install the regdomain package. Google didnāt help either. I am trying to create a basic wifi router. I donāt want to use Openwrt because it simply freezes.
apt-get install iw wireless-regdb
Afair crda was not available on ubuntu and i used this
$ sudo nano /etc/modprobe.d/cfg80211.conf
options cfg80211 ieee80211_regdom=US
Found documentation of ubuntu way in my wiki
Hello, Would it be possible to include Docker support in the image? I got the error:
docker run hello-world
docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error setting cgroup config for procHooks process: bpf_prog_query(BPF_CGROUP_DEVICE) failed: invalid argument: unknown.
i have added the cgroups_bpf option to my kernel and currently rebuilding imagesā¦
can you confirm the wifi-regdomain way works?
edit: pipeline finishedā¦

You posted a link to Bookworm 6.6.36. There was no problem with the 5GHz AP. Here the AP works probably fine - I connect to it with a Raspberry Pi 5. Regdomains were problematic in Ubuntu. So I tried the new June 30 Bookworm 6.6.36 image. Docker works fine. I donāt know why wlan1 is not active after boot. I have to activate it in the boot process using
ExecStart=/usr/sbin/hostapd /etc/hostapd/hostapd_wlan1.conf
After boot, wlan1 and wlan0 wonāt connect wireless client until I do
systemctl restart systemd-networkd
I also added it to the boot process. Then it works. Perhaps it would like to solve these two shortcomingsā¦ Otherwise perfect job!
The link is for all images which are built automaticly for all boardsā¦ubuntu is now noble (24.04).
Hostapd for wlan1 can only start if the regulatory domain is set at this timeā¦but this should only needed for 5g (wlan1)ā¦2g4/wlan0 should work on boot
How to set up a regulatory domain?
