openssh not working since updating to kernel 5.15
Bumped against similar issues with ssh servers (also dropbear) and the problem turned out to be a "lack of entropy". It takes the ssh server up to several minutes to initialize on an embedded system,

systemd: how to enable auto-loading kernel modules
Guess you'll have to provide more than just "It doesn't work" if you want any serious assistance. The source code would help. Also telling us whether the drivers actually probe if you load them manual

Likely there's a problem with the underscore. Recipes (and packages) with an underscore don't work properly because it's used as a version separator. Rename "my_module" to "my-module". Having said tha

Switching between multiple DISTROs without "contamination"
Hi Nicolas, I guess part of your problem is that DISTRO does not end up in any package grouping, unlike MACHINE and ARCH and so. So if OE/Yocto does The Right Thing, this means that it will have to re

Quick answer: Don't build multiple distros in one build directory. You might get away with setting TMPDIR = "tmp-${DISTRO}" to give each its own. But I'd rather advice to set up two separate builds an

Customizing SERIAL_CONSOLES
I'd suggest adding some "bogus" things to your machine-extra.conf, because I don't think the file will actually be used (or even parsed) anywhere. You can override SERIAL_CONSOLES in your DISTRO confi

Make psplash wait for the framebuffer to be ready
Ah, just writing to the list appeared to have helped. For the dependency to work, you need both a "Requires" and an "After" directive, i.e. [unit] ... Requires=sys-devices-platform-gpu-graphics-fb0.de

what to include in a "hardware bringup image"?
I tend to use a reasonably standard image, usually the one that will evolve into the product, and once the network (usb, ethernet or wifi) is up, use "opkg install" to grab whatever else I need from m

Compiling and packaging libraries
The simplest solution is to use autotools or Cmake for your project. That will automatically "do the right thing" to get the library properly installed and registered. Even if your project is just one

We're sharing the sstate-cache on plain Ubuntu LTS machines, all installed from wherever, and no issues with low hitrates. Even if the build server was running something like ubuntu 14 and "my" machin

initramfs with mdev: No match for argument: busybox-mdev
My guess is that your busybox isn't configured to produce mdev. Run "bitbake -c menuconfig busybox" and enable it (and save the config fragment for later)

What are the key factors for yocto build speed?
I tried compiling octave on an ARM board with 1GB of RAM (because octave is virtually impossible to cross-compile). There was one C++ in there that triggered a huge memory load of about 1GB, thus fail
