In Yocto Project to access the busybox menuconfig system:

bitbake -c menuconfig busybox

bitbake busybox

bitbake fsl-image-fb

01. Execute the command menuconfig on the package busybox. This allows customization of busybox applets

02. Run all the tasks for package busybox

03. Create the final image, in this case the frame buffer image, see tmp/deploy/images for outputs.

It's good to add it in a project specific layer and save it there with a busybox_<version>.bbappend instructing bitbake to check the layer's path for overrides. This allow for later reuse of the changed configuration and also store of it under a SCM system (as GIT, for example).

Hi Otavio,

Could you elaborate on how this is best done with the Busybox Yocto build.

I am trying to enable 'init' within BusyBox which isn't enabled by the default configuration.

I have tried the following:

1. Run menuconfig  and enable 'init' configuration option.

     bitbake -c menuconfig busybox

2. Create a patch file for the of the changes to the '.config' file

     diff -Naur .config.old .config > busybox-enable-init-config.patch

3. Add the patch file to my custom board layer in the busybox.bbappend file and copy the patch file into the appropriate location.

     SRC_URI_append = " file://busybox-enable-init-config.patch"

This then fails to build:

ERROR: Command Error: exit status: 1  Output:

Applying patch busybox-enable-init-config.patch

can't find file to patch at input line 3

Perhaps you used the wrong -p or --strip option?

The text leading up to this was:


|--- busybox-1.23.1/.config.old 2015-11-26 14:59:46.616876464 +1000

|+++ busybox-1.23.1/.config 2015-11-26 15:41:16.032997933 +1000


No file to patch.  Skipping patch.

This fails because the .config file doesn't exist at this stage of the build.

How should I apply my required changes to the Busybox configuration? Which file needs to be changed?

New Yocto Project releases allow the use of "config fragments" to change busybox settings.

You can add fragments and append them in SRC_URI. One example:
