Couldn't write/read CAAM registers in imx6

[ma_sreelakshmi]

Hi

I want to use CAAM for random number generation...But i couldn't write/read to CAAM job ring registers.. I tried with other CAAM registers but same...I came to know that i need more permissions to write to those registers...(correct me if i am wrong)

Can anyone suggest me what are the permissions we need to write/read in CAAM registers...?

i am a beginner in CAAM

Thanks in advance

Hi Sreelakshmy

very simple caam tests can be found in sdk:

rt-thread/caam_test.c at master · RT-Thread/rt-thread · GitHub 

or linux:

imx_sec_apps - i.MX Security Application Examples
