Function Documentation

◆ ifx_se_mpc_config_rot_mpc_struct()

ifx_se_status_t ifx_se_mpc_config_rot_mpc_struct	(	const ifx_se_mpc_rot_cfg_crc_t *	mpc_config,
		void *	ctx
	)

Initializes the MPC by setting the PC, NS/S and RW/R/W permissions for RRAM memory region.

This function allows to configure only one MPC structure: RRAM Host port with permissions for PC>1. Can be called by PC=2 only and does not allow to modify MPC configuration for the regions PC=2 does not have access to.

Parameters

[in]	mpc_config	The pointer to the MPC configuration structure.
[in]	ctx	The pointer to the SE syscall context that contain a special syscall data (IPC release callback etc).

Returns: IFX_SE_SUCCESS for success or error code

◆ ifx_se_mpc_lock()

ifx_se_status_t ifx_se_mpc_lock ( void * ctx )

Locks the MPC configuration.

This function allows to lock only one MPC structure: RRAM Host port
