I want to use some of the device tree overlays that the official Raspberry Pi kernel offers: disable-wifi and disable-bt. These overlays are not available in the Debian or mainline linux kernel.
I tried the following, found in the Raspberry Pi Linux kernel documentation:
Code: Select all
git clone --depth=1 --branch rpi-5.10.y https://github.com/raspberrypi/linux
cd linux
KERNEL=kernel8
make bcm2711_defconfig
make -j4 dtbs
sudo cp arch/arm64/boot/dts/overlays/*.dtb* /boot/firmware/overlays/
sudo cp arch/arm64/boot/dts/overlays/README /boot/firmware/overlays/
Code: Select all
sudo cp arch/arm64/boot/dts/broadcom/*.dtb /boot/firmware/
Then I added the lines
Code: Select all
dtoverlay=disable-wifi
dtoverlay=disable-bt
How can I disable wifi and bluetooth such that the chips are not even switched on?
Sincerely, Procyon
