connman is working until I install openjdk-7-jre and reboot afterwards. During the reboot I get message:

[FAILED] Failed to start Connection service.
See 'systemctl status connman.service' for details.

and

root@colibri-vf:~# systemctl status connman.service

Has anyone an idea to solve this problem?

Hi PrS

Welcome to the Toradex Community.

Could you provide the Software version of your module? Which carrier board are you using?

I’m using the Colibri Eval board.

root@colibri-vf:~# uname -a
Linux colibri-vf 4.4.88-2.7.4+ge0f2806 #1 Thu Oct 5 03:26:05 UTC 2017 armv7l GNU/Linux

Best, PrS

Thanks for the information. Could you send the complete dmesg log in a text file? How did you install openjdk? Thanks.

I install it, as described at your homepage:

wget -P /etc/opkg/ http://feeds.toradex.com/extra/2.5/conf/all/extra.conf
opkg update
opkg install openjdk-7-jre

Attached I send you the dmesg log file. link text

Best, PrS

hi, this openjdk-jre is for the bsp 2.5. For Bsp 2.7, you need to compile yourself an image with openjdk-7-jre doing OpenEmbeddedBuild and add Java support as described here.

Hi,
I tried it many time to compile my own image with Java, as described at the links, but I always get the following error, when I try to attach Java to the image:

ERROR: libecj-bootstrap-native-3.6.2-r5.0 do_unpackpost: Function failed: do_unpackpost (log file is located at /home/cholzner/oe-core/build/tmp-glibc/work/x86_64-linux/libecj-bootstrap-native/3.6.2-r5.0/temp/log.do_unpackpost.16917)

I attached it in local.conf

PREFERRED_PROVIDER_psplash-support = "psplash-angstrom"

+ IMAGE_INSTALL_append = " openjdk-7-jre"

At the descriptions for compiling an own image, linux version 2.8 is used, but Java for version 2.6. Could this be the problem?

Best,

PrS

Yes, you certainly can’t mix and match versions. Make sure to use somewhat recent proper rocko branch for a rocko aka BSP 2.8 build.

Now it is working, thanks!

Perfect. You are welcome.
