CRDA is a udev helper for communication between the kernel and - userspace. CRDA is no longer needed as of kernel v4.15 since commit 007f6c5e6eb45 («cfg80211: support loading regulatory database as firmware file») added support to use the kernel’s firmware request API which looks for the firmware on /lib/firmware. Because of this CRDA is legacy software for older kernels. So it looks like you need to install package/wireless-regdb instead of CRDA.
Thanks for the hint! Sorry, that it took me so long to test it and reply. Please see the new patchset https://lists.buildroot.org/pipermail/buildroot/2024-March/688611.html BTW, why are there WiFi drivers in the first place? The readme for the board refers only to the "nic,model=virtio" (https://github.com/buildroot/buildroot/blob/master/board/pc/readme.txt) So adding a bunch of network firmware seems pretty arbitrary to me. Is there any particular reason for this? Or maybe all this can be considered as legacy and removed?

Central Regulatory Domain Agent is used by the Linux kernel cf80211 wireless subsystem. Currently this package is not enabled and kernel complains with the following message on every boot: """ platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 cfg80211: failed to load regulatory.db """ Add CRDA package to fix the issue.
