Segmentation fault while executing mender

General Discussions
1

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

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
4

Hello Mirzak,

Thank you for replying.

I am producing the output you requested,

$ readelf -A /usr/bin/mender

/usr/bin/mender: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=f98599d13fd87825f50e6faa2991f4ceb0077c19, stripped

Its an issue with enabling GO binary. I have rectified it by enabling GO_CROSS_CGO_ENABLED?=“1” in local.conf and used the version of go_cross_arm 1.8.1. The segmentation fault is now solved.

Thank you for the help.
