Hello I need some help to understand this behaviour.
When I run my code (FreeRtos) step by step , into the vPortSVCHandler we call a function with BX R14 , but R14 is shown to be 0xFFFFFFFD .....
Can somebody tell me why ?
We get in this function with a SVC 0 call....
The call is correctly performed to ITaskStartup ....
Thanks
Either the value was directly loaded into the register, or the value was indirectly loaded into the register, or the value was the result of some manipulation.

Hello Franc ,
Thanks for this link : in fact it's quite normal, it is an Exception entry EXC_RETURN value.
I didn't know.
It will improve my knowledge of the Cortex .....
Best Regards.
