How to enable CAAM in MCIMX6UL-EVK

ko-hey — Thu, 13 Oct 2016 01:43:24 GMT

Hi all

My customer want to test a CAAM function in i.MX6UL.
Because they plan to use the CAAM as a encription engine of openssl.

they tried to test CAAM by reference to following thread.
https://community.nxp.com/message/447685
Also they checked kernel configuration, libaf_alg and boot parameters.
However, the CAAM didn't work.

Can user test the CAAM function with MCIMX6UL-EVK ?
If yes, could you let me know how to test the CAAM in MCIMX6UL-EVK.

Here is their test environment

Board: MCIMX6UL-EVK
BPS: L4.1.15

Hello,

Please use the recent Linux BSP for i.MX6 :

Summary Page :

i.MX 6 Series Software and Development Tool|NXP

Chapter 50 [CAAM (Cryptographic Acceleration and Assurance Module)]

of “i.MX_Linux_Reference_Manual.pdf” describes CAAM driver options.

Section 9 (Security) of “i.MX_Linux_User's_Guide.pdf” shows how to test

CAAM driver.

Have a great day,

Yuri

If you check the kernel boot log, you will see the caam driver demo print out

Also you can see the CAAM hardware accelerate the ssh guide in BSP document i.MX_Linux_User's_Guide.pdf, which is a good test.
