Function Documentation
◆ TZ_AllocModuleContext_S()
| TZ_MemoryId_t TZ_AllocModuleContext_S | ( | TZ_ModuleId_t | module | ) |
Allocate context memory for calling secure software modules in TrustZone
- Parameters
-
[in] module identifies software modules called from non-secure mode
- Returns
- value != 0 id TrustZone memory slot identifier
- value 0 no memory available or internal error
◆ TZ_FreeModuleContext_S()
| uint32_t TZ_FreeModuleContext_S | ( | TZ_MemoryId_t | id | ) |

- Parameters
-
[in] id TrustZone memory slot identifier
- Returns
- execution status (1: success, 0: error)
◆ TZ_InitContextSystem_S()
| uint32_t TZ_InitContextSystem_S | ( | void | ) |

- Returns
- execution status (1: success, 0: error)
◆ TZ_LoadContext_S()
| uint32_t TZ_LoadContext_S | ( | TZ_MemoryId_t | id | ) |
Load secure context (called on RTOS thread context switch)
- Parameters
-
[in] id TrustZone memory slot identifier
- Returns
- execution status (1: success, 0: error)
◆ TZ_StoreContext_S()
| uint32_t TZ_StoreContext_S | ( | TZ_MemoryId_t | id | ) |
