5.2 密码长度

  1. 演示代码 – boot_configwithPassword.h；密码
    #define PASSWORD_WORD_LEN                                                  (4U)
#define DebugAccess_Password0                                      (0x00000001)
#define DebugAccess_Password1                                      (0x00000002)
#define DebugAccess_Password2                                      (0x00000003)
#define DebugAccess_Password3                                      (0x00000004)
  2. 演示代码 – boot_configwithPassword.h：BCR_Config 结构中的密码
    /* Bootcode user configuration structure */
typedef struct
{
    /*! Configuration signature */
    uint32_t bcrConfigID;
    /*! Enable/disable AHB-AP, ET-AP, PWR-AP.
     * One of @ref BCR_CFG_DEBUG_ACCESS */
    BCR_CFG_DEBUG_ACCESS debugAccess;
    /*! Enable/disable SWD port access. One of @ref BCR_CFG_SWDP_MODE */
    BCR_CFG_SWDP_MODE swdpMode;
    /*! The factory reset mode. One of @ref BCR_CFG_FACTORY_RESET */
    BCR_CFG_FACTORY_RESET factoryResetMode;
    /*! Non Main Flash Static Write Protection.
    * One of @ref BCR_CFG_NON_MAIN_STATIC_PROT */
    BCR_CFG_NON_MAIN_STATIC_PROT staticWriteProtectionNonMain;
    /*! Programs static write protection of first 32K bytes.
     * One bit corresponds to one sector, LSB is Sector 0. Setting a bit
     * to 0 disables write, setting a bit to 1 enables write Possible values:
     *    - 0x0 to 0xFFFFFFFF */
    uint32_t staticWriteProtectionMainLow;
    /*! Programs static write protection of first 32K bytes.
     * One bit corresponds to eight sectors. Setting a bit
     * to 0 disables write, setting a bit to 1 enables write Possible values:
     *    - 0x0 to 0xFFFFFFF0 */
    uint32_t staticWriteProtectionMainHigh;
    /*! Reserved */
    uint32_t reserved;
    uint32_t password0;
    uint32_t password1;
    uint32_t password2;
    uint32_t password3;
    //Can add password length if needed
} BCR_Config;
  3. 演示代码 – boot_configwithPassword.c：将 BCRConfig_origi 变量更改为配置 Nonmain
    PLACE_IN_MEMORY(".BCRConfig")
const BCR_Config BCRConfig_origin =
{
    .bcrConfigID          = 0x3,
    .debugAccess          = BCR_CFG_DEBUG_ACCESS_DIS,
    .swdpMode             = BCR_CFG_SWDP_EN,
    .factoryResetMode     = BCR_CFG_FACTORY_RESET_DIS,
    .staticWriteProtectionNonMain  = BCR_CFG_NON_MAIN_STATIC_PROT_DIS,
    .staticWriteProtectionMainLow  = CFG_DEFAULT_VALUE,
    .staticWriteProtectionMainHigh = CFG_DEFAULT_VALUE,
    .reserved = 0xFFFFFFFFU,
    .password0 = DebugAccess_Password0,
    .password1 = DebugAccess_Password1,
    .password2 = DebugAccess_Password2,
    .password3 = DebugAccess_Password3,
};
  4. 演示代码 – check_password.c：Para_init 函数
    void Para_init(void)
{
    AHPAccess = false;
    BCRConfig_update.bcrConfigID          = 0x3;
    BCRConfig_update.debugAccess          = BCR_CFG_DEBUG_ACCESS_DIS;
    BCRConfig_update.swdpMode             = BCR_CFG_SWDP_EN;
    BCRConfig_update.factoryResetMode     = BCR_CFG_FACTORY_RESET_DIS;
    BCRConfig_update.staticWriteProtectionNonMain  = BCR_CFG_NON_MAIN_STATIC_PROT_DIS;
    BCRConfig_update.staticWriteProtectionMainLow  = CFG_DEFAULT_VALUE;
    BCRConfig_update.staticWriteProtectionMainHigh = CFG_DEFAULT_VALUE;
    BCRConfig_update.reserved = 0xFFFFFFFFU;
    BCRConfig_update.password0 = DebugAccess_Password0;
    BCRConfig_update.password1 = DebugAccess_Password1;
    BCRConfig_update.password2 = DebugAccess_Password2;
    BCRConfig_update.password3 = DebugAccess_Password3;
}
  5. 演示代码 –check_password.c：Nonmain_check 函数
  6. mspm0_cs_dap_init_V2： Password_LENGTH
    #define PASSWORD_LENGTH                                                  (4U)
  7. mspm0_cs_dap_init_V2：GEL_MSPM0_C_PasswordAuth(autoReset) 函数。密码长度已更改，无法将 CCS GUI 用作人机界面，因此用户需要在 CCS 脚本中添加实际密码，并发送调试器进行传输。
