OTA Version Usage Notes

  1. Currently, the OTA files supported by the RTL8773E series watch include: APP_Config, VP_Data, dsp_app, dsp_sys, dsp_config, sys patch, stack patch, boot patch, APP, and User Data (configured to support OTA).

Note

  • After OTA, you can visually confirm whether the upgrade was successful through the version number.

  1. Method for Modifying Version Number

  • APP_Config and VP_Data need to have their version numbers changed in the McuConfig Tool, and flash_map.inimust be added for regeneration.

    Modify APP_Config and VP_Data Version Number

  • The version number of dsp_app and dsp_sys files is updated with the DSP version release, while the version number of dsp_config can be customized in the DSPconfig Tool under Customer Info.

    Modify dsp_config Version Number

  • The version numbers for sys_patch, stack_patch, and boot_patch are generated based on different code bases when Realtek releases the SDK.

  • The version number for the APP can be modified at the corresponding location in version.h, and if flash_map.ini is updated, the corresponding flash_map.h needs to be updated for compilation.

  • The User Data file can be set to support OTA during flash map allocation, and the version number can be set in Prepend Header for User Data.

  1. Definition of Version Number Fields

    //APP:
struct {
   uint32_t _version_major: 4;
   uint32_t _version_minor: 8;
   uint32_t _version_revision: 9;
   uint32_t _version_buildnum: 11;
} app_sub_version;

//PATCH(sys_patch, stack_patch, boot_patch):
struct {
   uint32_t _version_major: 4;
   uint32_t _version_minor: 8;
   uint32_t _version_revision: 15;
   uint32_t _version_reserve: 5;
} sub_version;

//dsp app/dsp sys/dsp cfg version:
struct {
   uint32_t  customer_info : 8;
   uint32_t  svn_version_revision: 8;
   uint32_t  svn_version_minor: 8;
   uint32_t  svn_version_major: 8;
}versionNew;

//Others:
struct {
   uint32_t _version_buildnum: 8;
   uint32_t _version_revision: 8;
   uint32_t _version_minor: 8;
   uint32_t _version_major: 8;
} xx_sub_version;

    One can refer to the structure T_IMG_HEADER_FORMAT member T_VERSION_FORMAT git_ver to obtain the version information of the corresponding image from the image header.
