Troubleshooting • CM4 wlan0 is not there after "upgrading" to bookworm

$

As in the title. I have a CM4 that I've simply installed directly using the Raspberry Pi Image, V1.8.5 (latest as far as I know). When I use the Raspberry Pi OS Lite (64-bit), there is no wlan when I look using ifconfig, or if there is, it has no uuid and definitely no IP address.

If I do exactly the same thing, but with Raspberry Pi OS (Legacy 64-bit) Lite, I find a wlan0 and all is well.

This: viewtopic.php?p=2124403&hilit=cm4+wlan0 ... m#p2124403 says that it's a Debian problem, not a Raspberry Pi OS problem, but either way, it's a problem.

I suspect that a combination of Bullseye and my code was leading to a memory leak, and that leak is definitely not there in Bookworm, but on the other hand, neither is the wireless!

All help welcome.

Bob
