I there any guide for using CAAM as crypto engine in OPTEE

[jiankang]

Dear NXP engineers,

I want to using CAAM as the default crypto engine in OPTEE

is there any guide can help me doing it ?

Thanks a lot!

hello bulat_a,

For imx8qm serials, does it support CAAM in OPTEE ?

as I checked,  CFG_NXP_CAAM was force set as false...

else ifneq (,$(filter $(PLATFORM_FLAVOR),$(mx8qm-flavorlist)))
$(call force,CFG_MX8QM,y)
$(call force,CFG_ARM64_core,y)
$(call force,CFG_IMX_SNVS,n)
CFG_IMX_LPUART ?= y
CFG_DRAM_BASE ?= 0x80000000
CFG_TEE_CORE_NB_CORE ?= 6
$(call force,CFG_NXP_CAAM,n)
$(call force,CFG_IMX_OCOTP,n)

thanks.

Hi Jiankang

by default CAAM is used as crypto engine in OPTEE, also may be useful

Hi @jiankang 

layer for yocto:

https://source.codeaurora.org/external/imx/meta-imx-optee/

implementation optee from nxp

https://source.codeaurora.org/external/imx/imx-optee-os/tree/core/drivers/crypto/sub.mk?h=github/mas...

set 

CFG_NXP_CAAM

to have CAAM as a crypto engine
