SMC(Secure Monitor Call) for SMP on NXP S32V234

[tom_yeon]

Hi, This is tom.

I'm porting vxWorks BSP on top of NXP S32V234.

I tried to call SMC to wake the secondary CPUs, but the system reboots right after calling SMC.

See the log1 for u-boot information.

1. I wonder the boot code supports SMC standard.

2. Is there any other way to wake the secondary CPUs for S32V234?

thanks

Hi tom.yeon@windriver.com‌,

Right know we support only the Vision SDK in NXP Model-Based Design Toolbox for Vision and we don't have enough expertise on hardware related problems.

We recommend you to ask about this error in S32 Design Studio‌ community, they should know more about the S32V234 hardware.
