Core Data Management

MXOS System Core Data Management

To efficiently manage system core data, mxos defines a system core data structure: mxos_Context_t,

which is used to store system core data and provides a set of core data management API functions.

1. Core Data Managment API List

Core Data Managment API	Description
mxos_system_context_init	Initialize the core data used by the mxos system framework, and the system and application configuration is read from FLASH.
mxos_system_context_get	Read core data address
mxos_system_context_get_user_data	Get the application configuration data address
mxos_system_context_restore	Restore to the default configuration, the callback function will assign a default value to the application configuration data
appRestoreDefault_callback	The application sets a default value for the configuration parameters
mxos_system_context_update	Write configuration data managed by core data to FLASH

The main structure definition and function API interfaces are described below:

2. mxos_Context_t

Core data structure definition：

typedef struct _mxos_Context_t
{
  /*Flash content*/
  system_config_t           flashContentInRam;
  mxos_mutex_t              flashContentInRam_mutex;

  void *                    user_config_data;
  uint32_t                  user_config_data_size;

  /*Running status*/ 
  system_status_wlan_t      mxosStatus;
} system_context_t;

Among them：

flashContentInRam：System flash configuration parameter structure, please refer to： system_config_t
flashContentInRam_mutex： Flash operation mutex structure
user_config_data：User configuration data
user_config_data_size：User configuration data length
mxosStatus： mxos running state structure, please refer to ： system_status_wlan_t

3. system_config_t

The structure definition：

typedef struct {

  /*OTA options*/
  boot_table_t             bootTable;

  /*mxos system core configuration*/
  mxos_sys_config_t        mxosSystemConfig;

#ifdef mxos_BLUETOOTH_ENABLE
  mxos_bt_config_t         bt_config; 
#endif
} system_config_t;

Among them:

boot_table_t bootTable：bootloader Mode table information
mxosSystemConfig：System core configuration structure

4. system_status_wlan_t

The structure definition：

typedef struct
{
  system_state_t        current_sys_state;
  mxos_semaphore_t      sys_state_change_sem;
  /*mxos system Running status*/
  char                  localIp[maxIpLen];
  char                  netMask[maxIpLen];
  char                  gateWay[maxIpLen];
  char                  dnsServer[maxIpLen];
  char                  mac[18];
  char                  rf_version[50];
} system_status_wlan_t;`
