Dear NXP team.

 

I have some question how to control CAAM H/W.

 

I have ls1021A-IOT board and i.mx6qsabreauto.

 

LS1021A-IOT board boot and CAAM work well with non-secure mode .

 

And i.mx6qsabreauto board boot with secure mode.  So i changed linux kernel to boot with non-secure mode.

 

of course, modified the CSU_CSL17(CAAM) register to 0x00ff00ff so that CAAM can be accessible in both non-secure and secure worlds.

 

But CAAM is not working and I can not see value of caam register in non-secure mode . all of them(caam register values) are 0.

 

I really don't know why and what i should modify...

 

I could see ls1021x_config_caam_stream_id() code in u-boot code of ls1021a-iot.

 

Question.

     1. I also need to add kinds of ls1021x_config_caam_stream_id() for i.mx6qsabreauto?

     2. could you explain about ls1021x_config_caam_stream_id()?

 

Have a great day.
