The STKALIGN bit reset value in the Configuration and Control Register at address 0xE000ED14 has been inverted. The reset value is now 1, which means that the stack frame is 8-byte aligned by default. Configuration Control Register.


The generic uC/OS-II Cortex M3 port assumes that stack frame is 4-byte aligned, in order to be consistent
with the port you must cleat the reset value to ‘0’
