ADDRERRF bit getting set on PKA init

Hello,

I am trying to use the PKA module on a STM32U5 controller. I have configured the clock at 160Mhz and also initialized the Ring. However, when I try to initialize the PKA, it runs into ADDRERRF = 1, I was expecting ofcourse INITOK to be 1. Does anyone have Idea what am I missing here or what might be causing the ADDRERRF?

 

Thanks,

Abhi

Trying to clarify to avoid misunderstanding. I meant both the bits ADDRERRF and INITOK are set to 1 after I call the init function. I see in the debugger that the RNG is running.

Hello @abhisheksirsikar 

Are you using the HAL library?

yes. I just ignored the error bit and everything works as expected. But I couldn’t figure out why the error bit is getting set
