I am trying to integrate Mender to i.MX6 Sabresd board and am able to generate mender binaries in the RootFS. I am able to boot the board but while executing the mender binary, I am getting a segmentation fault error. Details, **Yocto** : Morty **Kernel** : 4.1.15-2.0.0+g30278ab **Mender version** : 1.5.0 Below are the logs, **$ mender** Segmentation fault **$ ldd /usr/bin/mender** linux-vdso.so.1 (0x7ea14000) libpthread.so.0 =\> /lib/libpthread.so.0 (0x76edf000) libc.so.6 =\> /lib/libc.so.6 (0x76df1000) /lib/ld-linux-armhf.so.3 (0x76f04000) **$ gdb mender** GNU gdb (GDB) 7.11.1 Copyright © 2016 Free Software Foundation, Inc.

Hi @shivashankar, Welcome to Mender Hub, I can not think anything immediate why you would have this problem and the only thing that I can think of is that something went wrong during cross-compilation. We have integrated on a similar platform before and also morty, ``` https://hub.mender.io/t/compulab-cl-som-imx6/138 ``` I would try to re-build the mender client by running, ``` bitbake -c cleansstate mender && bitbake mender ``` To see if it solves the problem, otherwise I would start checking the built in properties of the compiled binary, e.g ``` $ readelf -A /usr/bin/mender ``` and ``` $ file /usr/bin/mender ``` ---
