System semaphores

Hi all.
I want to insert a fault in the RTOS system to test how my app react to it: I have to insert in the part of the semaphore, but I don’t know which register to change or where to find it.
my goal is to flip some bits in a register that the system use to manage semaphore internal to the RTOS, not the application ones.
Is it possible?

I’m not sure I understand the question. The RTOS does not use
semaphores internally, the only semaphores are the ones used by the

Thank you for the answer. Since our project involves a fault injection on semaphores and, as you said, there are no semaphores used internally by the RTOS is it possible to modify the way the RTOS manages the semaphores of our application? In other words, is there any variable that holds, for example, the priority of the user semaphores and can be modified? If there is any, how can we access to it?
