Re: Raspberry Pi Zero W - Defective WiFi chip

Well, I don't play around with Raspberry Pis because I have to, but because it's fun for me and I like to learn new things. I'd rather spend hours soldering a Raspberry Pi together in my free time than going to work for an hour. ;) I wasn't able to find a good source for the chip though. I think the...

Re: Raspberry Pi Zero W - Defective WiFi chip

Well, I don't think that I can return it for a replacement because too much time has passed since I bought it.
I have some equipment that might come in handy (a reflow station for instance) and I have some experience with SMD soldering. Is the WiFi chip available for consumers?

Raspberry Pi Zero W - Defective WiFi chip

I have a Raspberry Pi Zero W that apparently has a defective WiFi chip. If I put the SD card in another Pi Zero W (same version), the WiFi works just fine. Bluetooth seems to work though... at least a Bluetooth device is showing up. For the WiFi there is no device showing up. I have tried reinstalli...

Camera live stream with Pi Zero W using cvlc throws errors

I am trying to stream the video taken by the Pi camera live and in HD over the network, but I keep getting errors setting it up. I am using a Raspberry Pi Zero W with a Pi camera that is connected to the flat cable connector thingy. The camera's LED lights up and the device shows up in /dev/video0. ...

Re: Can't find `arch/arm/boot/dts/overlays` when building kernel

Hey it's me again, I already gave up and concluded that the official build instructions must be incorrect or the kernel sources are broken. I tried to use the non-rt rpi-4.14.y branch and it seems to have booted into the desktop environment, but both mouse and keyboard don't seem to work. Here is wh...

Re: Can't find `arch/arm/boot/dts/overlays` when building kernel

No, I'm actually building the kernel on an x64 build server inside a debian based docker container. (Well, for the last screenshot I actually ran the docker container on my local x64 Fedora machine so that I could mount the SD card to the container and install everything directly onto it.) So yeah, ...

Re: Can't find `arch/arm/boot/dts/overlays` when building kernel

First of all, PREEMPT_RT is already enabled by default so we don't need to enable that manually. Yes, I already realized that . :D I tested -rt branch in the case of aarch64 before. I noticed there was a warnning message: Failed to start Load Kernel Modules. in your case. I recommend you can instal...

Re: Can't find `arch/arm/boot/dts/overlays` when building kernel

I still can't get it to work. Here's the latest kernel image: https://gitlab.com/T-vK/rpi-rt-kernel-build-project/-/jobs/55360707/artifacts/raw/rpi-rt-kernel.tar.gz (as before, the kernel7.img is in the boot folder). This is how I copied it over: export KERNEL=kernel7 sudo cp /run/media/fedora/boot/...

Re: Can't find `arch/arm/boot/dts/overlays` when building kernel

No success so far. As soon as I put the kernel on my Pi, it will fail somewhere in the boot process. So I tried to flash a fresh install of Raspbian, but again the rt-kernel breaks it. I also tried to flash the pre-built kernel that is provided in this guide : http://download.frank-durr.de/kernel-4....

Are these cheap USB HDMI capture cards compatible with the Pi?

I recently found a guide on how to create an ambilight for any TV using a Raspberry Pi, an analogue cinch capture card, an HDMI to cinch converter and an HDMI Y cable. The whole thing was really pricey and I wonder if it wouldn't be way easier and cheaper to just buy one of these $14 no-name USB cap...

Re: Can't find `arch/arm/boot/dts/overlays` when building kernel

Thank you so much PhilE!
I managed to successfully build both, the image and the deb packages.

image build output | image download
deb packages build output | deb packages download

Now I just need to test it. :)

Re: Can't find `arch/arm/boot/dts/overlays` when building kernel

Awesome! Does running `make bcm2709_defconfig` result in the desired .config or do I have to manually go through `make menuconfig` to set `Preemption Model` to `Fully Preemptible Kernel (RT)`?

Can't find `arch/arm/boot/dts/overlays` when building kernel

I'm currently working on a project that automatically builds the Raspberry Pi kernels as real-time kernels. Everything seems to work as expected so far. But it looks like I'm missing a directory after the build process. $ cp -r /linux/arch/arm/boot/dts/overlays $INSTALL_MOD_PATH/boot cp: cannot stat...
