hello,
I'm working on imx8 serial products.
I try to build OPTEE from branch:lf-5.10.y_2.0.0
but TEE boot up failed with the error below:
UE/TC:0 0 sc_seco_start_rng:101 Unable to start RNG or get RNG status
E/TC:0 0 sc_seco_start_rng:102 sc_error code is: 7
E/TC:0 0 caam_hal_rng_instantiated:20 RNG instantiation failed
E/TC:0 0 crypto_driver_init:56 caam_rng_init() (1)
E/TC:0 0 crypto_driver_init:172 CAAM Driver initialization (0xffff0000)
E/TC:0 0 Panic at core/drivers/crypto/caam/caam_ctrl.c:173 <crypto_driver_init>
E/TC:0 0 TEE load address @ 0xfe000000
E/TC:0 0 Call stack:
E/TC:0 0 0x00000000fe008f50+
error code 7 indicates CAAM didn't power on.
so how can I power on CAAM in OPTEE or somewhere else ?
thanks a lot.
