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

Switching between multiple DISTROs without "contamination"
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

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

Seems a bit excessive to buy hardware just to handle a particular corner case. Most of OE/Yocto code is plain C, not even C++. My rig only has 8GB but doesn't run into memory issues during big GUI bui
