Board not booting if CONFIG_CRYPTO_DEV_FSL_CAAM enabled

[pratyushtomar]

We have a custom board which uses imx6ul processor. The board signed with keys using cst tool. If we enable CONFIG_CRYPTO_DEV_FSL_CAAM in deconfig then the board stops booting midway. But if we disable CONFIG_CRYPTO_DEV_FSL_CAAM in deconfig then board boots normally and and there is no problem in board functioning. Why does the board doesn't work on enabling CONFIG_CRYPTO_DEV_FSL_CAAM? We are official yocto available for imx6ul.

Hello,

   Please check if you have unlocked RNG in CSF script.

    Engine = CAAM

    Features = RNG

Have a great day,

Hello,

  Have You ever manged to use CAAM under Linux, using unsigned images? 

Regards,

Yuri.

No I have never used CAAM under linux using unsigned image. I don't need to use CAAM. Actually I need to  use key blob but I was facing problem unknown symbol sm_detect_keystore_units . I thought it might be because I have disabled CAAM in defconfig but I guess there is no relation between 2 problems. I am using following in defconfig file

CONFIG_CRYPTO_DEV_FSL_CAAM is not set
CONFIG_CRYPTO_DEV_FSL_CAAM_SM=y
CONFIG_CRYPTO_DEV_FSL_CAAM_SM_KEY_BLOB=y
CONFIG_CRYPTO_DEV_FSL_CAAM_SM_TEST=y
CONFIG_CRYPTO_DEV_FSL_CAAM_SECVIO=y
