S32K3 系列芯片在设计时引入了Life Cycle 的概念，在不同的 Life Cycle 时芯片有不同的权限，JTAG 调试端口的开启关闭也是通过该配置来进行控制的,对应的 Life Cycle  类型说明如下：

针对不同的LC 芯片对DEBUG 端口的访问权限是不同的。

芯片的生命周期的推进需要谨慎，一旦向前推进后无法再向后恢复为之前的状态，LC 推进过程如下：

HSE lib 中对LC 的宏定义说明如下

/*==================================================================================================

/** @brief    HSE secure lifecycle definition (OTP-ADVANCE-ATTR attribute; refer to #hseAttrId_t).

 *            Warnings:
 *            - The lifecycle is read/scanned by hardware during the reset phase. Hence, a reset is recommended
 *            after each LC write-advance operation.

从上述代码的注释中可知“The lifecycle can be advanced to OEM_PROD/IN_FIELD only if the #HSE_APP_DEBUG_KEY_ATTR_ID attribute was set before.” 在推进芯片的生命周期至OEM/IN_FIELD 前ADKP 必须先进性配置好方可推进生命周期。

secure debug 的配流说明如下

以下是HSE lib 也是按照上述的流程中推进LC 和 ADKP 的配置代码，使用HSE 固件的时候使用 HSE 的服务即可完成对应ADKP 和 LC的配置。

ASSERT(HSE_SRV_RSP_OK == srvResponse);
}
