How to access SEMA42 address on S32G3 ?

xiuli_sun · ‎09-15-2023

Hi,

I am enabling LLCE on S32G3 with vxWorks. When I enable Rx intertupt, I need to write the sema42.

But when I write it, it will lead to my board reboot and I am sure the address is right.

Then I check in the reference manual, it says that the "You can access these registers only in Supervisor mode. User accesses terminate with an error." chapter 17, Page 766.

So how should I make the driver to work in Supervisor mode?

Looking forward to your replay.

Thanks a lot!

Hi xiuli sun

Okay, that's good. I conformed that Linux BSP does not contain any driver or information where SEMA42 IP is used.

I think supervisor mode is arm related. let me ask to our internal team if any information regarding this. I will update here
