I have here invalid value to LR when any normal ISR was happened. every Isr get the same behavior.
how can I know LR Value in this case to get the previous code line which was executed before this interrupt.
and why in call stack "exception Frame" appeared in a normal isr ? and where the previous call stack view before isr in call stack window?
Sorry for slow reply, I only noticed this question now.This is correct behavior, and is different to older Arm processors:http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0552a/Babefdjc.html
