Hi all i trying do transition from EL3 to EL2 exception ,but after ERET of EL3 mode it change the mode to EL2 , but as soon as when it will execute first instruction of EL2 , then It goes to Exception ...
This is happen for every secure to non secure transition in Armv8-A .
Please Guide if you know why this happen?
Thank you in advance.
Regards
Sanjay Kumar
NO after execution first instruction of EL2 mode, it is remains in EL2 mode only but it goes into unexpected handler..so i cant read EL3 regions registers.
