Is IMX27 HSM (Hardware Secure Module) supported?

[txh3157]

Does iMX27 include hardware secure module (HSM) for factory to write X.509 cert/key? Is the SCC the right module to look into? If it is, how to enable it from Yocto BSP's setup?

Hello txh3157,

The iMX27 does not include the HSM, The HSM is treated as a further core and can be full run controlled. Furthermore, common debugging of the Host/HSM cores and FLASH programming are possible on processor: MPC57xx and MPC56xx.

It is not possible for us to change schematic. In the iMX Linux reference doc, does these commands working in iMX27: sm_init_keystore, sm_detect_keystore_units, sm_establish_keystore etc under CAAM module? Can SCC module to be used by application?

Thank you!
