Is it possible to compile barry with debug information and run within GDB so that we can see which source line is causing an unaligned read? Do you get a similar error when running a different sample or tool (such as 'btool -l')? Are you using the 0.17 code or building from the git repository? If the latter then what's the head commit ID? I've certainly managed to have the channel support (which usbclient uses) working successfully on ARM hardware. I can't remember if I had alignment checking enabled or disabled though and I've not used usbclient on ARM ever. > Please suggest me, what could be the problem for getting above error. It's most likely that an unsigned char* is being cast to a large type and then dereferenced. If you get GDB working then it should be immediately obvious from the line where the unaligned access comes from. > Additionally pls explain me how to build a barry shared libraries. I've always just configured and made barry as normal and always got shared libraries from it. Did you explicitly disable shared libraries from being build for some reason?
