Dear freescale team.

 

I have questions about CAAM in i.mx6qsabreauto board.

 

I changed linux kernel to work in non-secure mode. of course, modified CSU to access peripherals in non-secure kernel.

 

But it occurs caam errors when booting kernel.

 

I think that i need to configure "Job Ring MID Register (JRMIDR)", "DECO MID Register (DECOxMID)"  in the guide of IMX6DQ6SDLSRM_security.pdf

 

i really don't know how to configure it well. it's not easy to understand the pdf guide file.

 

if i'm right,  is thers some  reference code?

 

And i saw "ls1021x_config_caam_stream_id()" in u-boot.

 

It says for supporting for initializing CAAM's stream id.

 

I'm not sure but the function is for adjusting JRMIDR, DECOxMID values?

 

Thank you.
