I have defined two main function for two flash/RAM region in Cortex M3, In first Main function (1st Bank) Region I configured MPU and Exception handlers before Jumping to 2nd Main function (2nd Bank) we call unprivileged. But in 2nd main function MPU is in privileged mode so if i try to call __svc function giving me memfault exception. how to achieve this scenario to get __svc call to SVC handler which is in First bank(1st Main) function.
