[meta-xilinx] Busybox options on 2016.2 meta-xilinx/meta-petalinux

That helped very much!  Thank you!   

 

I needed to add that into PACKAGES in the busybox.inc file.

Regards,

Katie

Hi,

 

"${@plnx_enable_busybox_package('dos2unix',d)}" should output "busybox-dos2unix".

So, you probably need to include the package "busybox-dos2unix" to your rootfs image.

 

To make sure the binaries are in that package - they should be in the busybox's workdir/packages-split/busybox-dos2unix/...

 

Regards,

Oleg

Hello,

 

I have a question about Busybox as it pertains to meta-petalinux layer / meta layer in the Xilinx/Yocto 2016.2 code.

 

I am using Petalinux 2016.2, and I have downloaded the Yocto source for this as per 

 

http://www.wiki.xilinx.com/Getting+Started+With+Yocto+using+Repo+to+build+RPM+Packages

 

I’m trying to build packages to use for the package feed for my Petalinux roofs.  To this point, I’ve built a couple of new packages (pax, tcpdump, nodejs) and I have been able to pull them into my rootfs in Petalinux.  I see them in the rootfs configuration and have enabled them.   

 

But now I need to turn on an additional feature in busybox and I am struggling.  I do not seem to be able to change any options with the busybox located in the Petalinux 2016.2 tools, so I am trying to enable this in the Yocto source and hoping to pull in that package to use.     

 

However, I am specifically having trouble enabling dos2unix in busybox for the Xilinx/Yocto 2016.2 release.  It seems that whatever I do, during the do_compile stage of busybox building, I see this snippet in the logs:

 

redefined by fragment .config.disable.apps:

 

and even when I have (via menuconfig) previously set dos2unix to y, both dos2unix and unix2dos are being unset and are not available in the rootfs after it is built.

 

Can anyone list the steps that I should be doing in order to enable a new function in Coreutils in Busybox, as it appears to be more involved than just using menuconfig and / or the steps below.

 

Here are the things I have tried in addition to “bitbake -c menuconfig busybox; bitbake busybox; bitbake petalinux-image”:

 

Adding a .cfg file with CONFIG_DOS2UNIX and CONFIG_UNIX2DOS both set to =y, this .cfg file is included in a SRC_URI_append in a .bbappend file in the meta-petaliux layer.  This file does show up in the work directory after I build, so it seems it is being included.

 

In the meta-petalinux layer, I have added the following lines to busybox_%1.bbappend:

PACKAGES =+ "${@plnx_enable_busybox_package('dos2unix', d)}"

INITSCRIPT_PACKAGES =+ "${@plnx_enable_busybox_package('dos2unix', d)}"

 

INITSCRIPT_NAME_${PN}-dos2unix = "dos2unix.${PN}"

INITSCRIPT_PARAMS_${PN}-dos2unix = "start 67 S ."

 

And at the end of 

def plnx_features_to_busybox_settings(d):

    pkgfeatures = {

 

I have added:

        "busybox-dos2unix" : [

            "CONFIG_DOS2UNIX", \

            "CONFIG_UNIX2DOS", \

        ],

 

 

But it isn’t working.  Busybox builds, but still no dos2unix.

 

I must be doing something wrong, or missing a step somewhere, so any help or point out another example to look at is much appreciated!

 

Thanks,

Katie
