#1 ARM Builds » [Raspberry Pi 400] Why is wifi interface named wlan1 on the Pi400? » 2021-11-25 19:35:56

Hi there,
I use Devuan on both Pi4b and Pi400, in aarch64 mode.
In both cases, I manually load the bcrmfmac module when it's needed.
The problem is that the WIFI interface is named WLAN0 on the Pi4b but it's named WLAN1 on the Pi400, and that breaks some of my scripts.
So, what could be at play here? Any clues?
Thanks!

@ShorTie: Yes, but throttling shouldn't cause video to go off. That's a different issue.

Hi there,
I successfully run Devuan 4.0 arm64 on a Pi4b, but HDMI screen turns off and never comes back when all 4 cores are used for long compilation tasks. The screen goes off and never comes back.
Note that I use the full KMS graphics stack, so in config.txt I have:
dtoverlay=vc4-kms-v3dAnd in cmdline.txt I have:
video="HDMI-A-1:1280x720@60"Note that all hdmi_* config options are ignored in full KMS mode, since it uses the standard Linux KMS interface instead of the Broadcom-propietary video interface that those hdmi_* options are for.
This bug also happened on Raspberry Pi OS at some point, but it was eventually fixed:
https://github.com/raspberrypi/firmware/issues/1598
It has to do with throttling: throttling is happening, but it shouldn't cause video to be disconnected.
Also, is there a Pi4 arm64 kernel package I can update via apt-get? The image comes with a custom PREEMPT kernel, which is great, but I don't know how to update the kernel or the firmware (dtbs, etc).
Thanks!
