[meta-intel] [meta-java]: kernel modules are missing after integrate java support in baytrail bsp.

Hi Jackie,

That worked. Thanks for the help. My bad, I did not realize the '+' is missing.

Thanks.

I think you need to use += or _append when you add packages in your bbappend.

Thanks,
Jackie

Hi all,

Currently I am trying to enable java support for valleyisland-32 bsp(core-image-sato image option).


I have followed all the Usage Instructions as mentioned in the meta-java About page.

I have also created a ./meta-netcontiki/recipes-sato/images/core-image-sato.bbappend with the following content in it:




IMAGE_INSTALL = "busybox modutils-initscripts initscripts opkg udev sysvinit netbase base-files base-passwd \
                 ${ROOTFS_PKGMANAGE_BOOTSTRAP} ${CORE_IMAGE_EXTRA_INSTALL} \
                 openjdk-8 openjre-8 \
                 strace dropbear binutils \
                 classpath \
                 classpath-common \
                 classpath-examples \
                 classpath-tools \
                 "

The java build process is fine. The build process never returned any error message and the image boots up fine.

I noticed another strange issue here. I was not able to execute commands such as $ ifconfig and  $ lsmod.
Even the spidev0.0 is missing in /dev/ directory.

After spending some time root causing this issue, I noticed that some driver files and modules are missing in /lib directory.
A standard valleyisland-32 bsp without java have the following components in /lib/modules/3.14.39ltsi-yocto-standard/kernel :
arch     crypto   drivers  fs       lib      net      sound

But, upon enabling java support, the /lib/modules/3.14.39ltsi-yocto-standard/kernel path has only :
net

I also noticed the /sys directory for bsp with java enabled seems to be empty.

I integrated java (openjdk-7-jre) into Quark BSP sometime back, the image is working fine. No such flaw as mentioned above.

I have spent some time looking into this issue but I am clueless.

Am I missing any settings or configurations? Please guide me.

Thanks in advance.


Thanks.

Regards,
RAJ
