Hi ,
I was working on a armv7l architecture platform and was trying to run webruntime related library, but it was crashing _armv7_tick(). So, I did GDB on the wrt binary and below are the logs:

0x2e2b76ec <+4>: bx lr
End of assembler dump.
It seems that either the architecture platform is not able to identify the instructions or some other reason, due to which it fails.
Has anyone faced similar problem? Could anybody suggest some solution or patch which can solve this issue?
Thanks,
Jay
