I've done changes according to you suggestions.
But still getting same issue....
Ok. Could you send the output again (the pc value has probably changed), and send me your 'ned' binary so that I can look up what instruction is at that location.

Could you switch to ARMv7 here as this is the corresponding version for a Cortex-A9.

I have gone through the code flow for "ned" and I found that the exception is raising while loading ned.lua script, At certain point luaK_prefix() is trying to call codearith() but failed to call codearith(). both the function are located at l4re/pkg/lua/lib/contrib/src/lcode.c
I'm able to get print statement which I placed before calling the codearith() in luaK_prefix(), But not printing the statement which I placed inside the codearith()
Can you please get me out from this issue.
Please check whether this persists after recompiling for ARMv7. If not, I'd like to know which instruction/code is at 0x1021984.
