Hi

I am working on Vybrid platform to enable RTIC feature. When I wrote those registers, the value I read back was always zero. Even I used U-boot. For example:

I wrote : CAAM_RTIC_BASE_PTR->RWDOG = 0xffff;

              CAAM_RTIC_BASE_PTR->RTHR = 0x1;

Then the value I read back was :

              CAAM_RTIC_BASE_PTR->RWDOG = 0x0;

              CAAM_RTIC_BASE_PTR->RTHR = 0x0;

Somebody can tell me why?

Thank you

Hello Dongsheng,

Ensure that, RTIC is not in Run-time mode before writing to those registers as they are read only while in Run-time mode. Use RSTA register to find out the state of RTIC.

Hi

Yes, before I wrote these registers. I checked RSTA register. It is always zero. Actually every registers are always zero. Even I read and wrote them with U-boot.

Thank you
