Bitbake (e.g. Yocto) suddenly hangs in the build step: parsing recipes. It does never reach 100%. How can I fix this ?
Delete the bitbake cache. E.g.:
rm tmp/cache/default-glibc/phyboard-mira-imx6-14/x86_64/*

Sometimes I run yarn (2) in the wrong directory, which can result in the download of thousands of files. Cleaning that up takes a lot of time.
Is there an easy way to prevent yarn from running in a certain directory?
I am using Windows, by the way. But an OS independent solution would be even nicer.
I found this solution:
In that directory create a subdirectory node_modules.
Remove the right to write in that subdirectory for the relevant user(s).
The result looks like this:
> yarn add cypress
yarn add v1.22.15
info No lockfile found.

An nothing is downloaded into that node_modules.
I'm learning Yocto project. Started creating an image for Raspberry Pi 4.
I ran bitbake rpi-basic-image and got an error:
fatal: repository '/PATH/yocto/rpi64-build/downloads/git2/github.com.ninja-build.ninja.git/' does not exist
but when i run bitbake -c menuconfig virtual/kernel everything dowloads and works fine.
I didn't find anything about it.
Can you share more of the build log? It looks like a previous download of ninja has been manually previously deleted, try deleting *ninja-build* in downloads/ and downloads/git/.

In yocto, I would like to review what will be built (packages and versions) in an image without actually building it (because it takes too much time). How could I achieve this?
bitbake -g core-image-minimal gives some information, but I would like something closer to the image manifest.
bitbake -e core-image-minimal does not give the list of all packages.
'bitbake -g core-image-minimal' will write a file 'pn-buildlist' which is a list of all recipes that are in the dependency tree.
I'm using Yocto for the first time for an ARM embedded system with a Xilinx Zynq.
I want to make some configuration changes that requires going in the menuconfig utility. Yocto documentation shows how to do it for the Linux Kernel
bitbake yocto-xlnx -c menuconfig
Which, for Xilinx, I turned into
bitbake linux-xlnx -c menuconfig
It works very well.
Now, I want to do the same with u-boot and change the .config file using the menuconfig utility. I can't find any way to do it in Yocto or Xilinx documentation. I tried the obvious like
bitbake u-boot-xlnx -c menuconfig
just to get an error message:
ERROR: Task do_menuconfig does not exist for target u-boot-xlnx
Any Idea how to get to u-boot menuconfig with Yocto?
Edit:
here are the layers I use

It's currently, as of 2.3 Pyro, not possible to run bitbake u-boot -c menuconfig as no-one has implemented that functionality for the U-Boot recipe. Please, file a bug if you'd have uses for this.
Normally, I'd recommend either of the following approaches:
bitbake u-boot -c devshell
Use of devtool.
Use the SDK.
All of these would not only allow you to run make menuconfig, but also to cross-compile U-Boot to verify your configuration.
I found the solution. It works for xilinx distribution. I did not test it for others but it's likely to be similar and it's likely to work for any other menuconfig of any package. It turns out that the full source package is located in my case at:
~/poky/build/tmp/work/zedboard_zynq7-poky-linux-gnueabi/u-boot-xlnx/v2016.07-xilinx-v2016.3+gitAUTOINC+95e11f6eb4-r0/build
I'll let you decode the "board, machine, version etc" coding in the folder string since it depends on each case, but just want to give the idea.
Using the terminal, just go to that folder then run just like in the old days:
make menuconfig
and voilà!
I guess when I get to configure busybox and things like that, it will just be the same.
I ran into the same problem.
I build u-boot-at91 for at91sam9x35, but it should be the same for other architectures as well.
Yocto still doesn't support
bitbake u-boot -c menuconfig
I managed to do it with the following steps:
In build directory run:
devtool modify u-boot-at91
This will automatically create the u-boot source files' external directory under: build/workspace/u-boot-at91.
cd build/workspace/u-boot-at91
run menuconfig using:
make menuconfig
If menuconfig doesn't show up you might have to run the do_configure task for u-boot and then retry:
bitbake u-boot-at91 -c configure
Perform required menuconfig changes in the UI and save the configuration in New.config file.
Copy the New.config file to override your target's defconfig file
(in my case at91sam9x5ek_spiflash_config) using:
cp New.config configs/at91sam9x5ek_spiflash_defconfig
Notice the defconfig suffix instead of config!
Push the change to your local git repository:
pushd build/workspace/sources/u-boot-at91
git add at91sam9x5ek_spiflash_defconfig
git commit -m "summary of changes made here"
git status
popd
Create the patch to override the default defconfig file:
devtool update-recipe u-boot-at91
This actually appends the following lines to your u-boot-at91.bb files:
SRC_URI = "git://github.com/linux4sam/u-boot-at91.git;protocol=https;branch=${UBRANCH} \
file://0001-summary-of-changes-made-here.patch \
and creates the patch file with relevant modifications to the recipe's directory.
8. Run BitBake:
bitbake u-boot-at91
or
bitbake core-image-minimal
The new u-boot binary will be built with the new configuration.
I'm trying to learn ember so I created a local git repository cloned from github so I could stay up to date with it. I've never used rake before so I also downloaded and installed that from http://rake.rubyforge.org/. Rake appeared to install correctly and when I ran rake --help I got the help options so I think it's all okay. So then in my command prompt, I did a CD to the directory that has the github files for ember. From my reading, since there's a Rakefile in the ember directory it sounds like I can just CD to that directly and run rake. But when I do that I get the following errors. I'm sorry but I have no experience with rake so I'm not sure what I am doing wrong... or if it's something in the build file?

You need to install bundler (so you can get all of the gems ember's rake tasks depend on).
gem install bundler
Then, inside your ember directory:
bundle install
