It means that the compiler converted your code to an instruction that the hardware does not support. This could however be something simple like disabled floating point operations. see infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0363g/… –Guru Prasad Mar 26 '15 at 17:27 add a comment| active oldest votes Know someone who can answer?
