【TI毫米波雷达笔记】SOC外设初始化配置及驱动（以IWR6843AOP为例）

最基本的工程建立好以后
需要给SOC进行初始化配置

	SOC_Cfg         socCfg;     //SOC配置结构体Task_Params     taskParams; //任务参数SOC_Handle      socHandle;ESM_init(0U);               //与安全等有关，可略过/* Initialize the SOC configuration: *//* 初始化SOC配置结构体 */memset ((void *)&socCfg, 0, sizeof(SOC_Cfg));memset((void *)&MMWave_Global_Params,0,sizeof(MMWave_Global));/* 配置SOC配置结构体 *//* Populate the SOC configuration: */socCfg.clockCfg = SOC_SysClock_INIT;socCfg.mpuCfg = SOC_MPUCfg_CONFIG;/* require to UNHALT the DSS if this core is available in selected device */socCfg.dssCfg = SOC_DSSCfg_UNHALT;/* Initialize the SOC Module: This is done as soon as the application is started* to ensure that the MPU is correctly configured. *//* SOC初始化，必须在系统运行后尽快调用该初始化函数 */socHandle = SOC_init (&socCfg, &errCode);if (socHandle == NULL){System_printf ("Error: SOC Module Initialization failed [Error code %d]\n", errCode);return -1;}

这是最基本的配置模板
包含了SOC时钟配置
MPU初始化和DSS初始化

而如果需要用到毫米波雷达和安全功能
则需要对BSS进行上电并进行安全配置

/* Wait for BSS powerup */if (SOC_waitBSSPowerUp(socHandle, &errCode) < 0){/* Debug Message: */System_printf ("Debug: SOC_waitBSSPowerUp failed with Error [%d]\n", errCode);return 0;}/* Check if the SOC is a secure device */if (SOC_isSecureDevice(socHandle, &errCode)){/* Disable firewall for JTAG and LOGGER (UART) which is needed by all unit tests */SOC_controlSecureFirewall(socHandle,(uint32_t)(SOC_SECURE_FIREWALL_JTAG | SOC_SECURE_FIREWALL_LOGGER),SOC_SECURE_FIREWALL_DISABLE,&errCode);}

最后把soc的句柄放在一个全局变量中结尾开启BIOS

MMWave_Global_Params.handle.socHandle = socHandle;/* Debug Message: */System_printf ("Debug: Launching the MMW HWA Demo\n");/* Initialize the Task Parameters. *//* 创建一个任务用于测试 */Task_Params_init(&taskParams);//taskParams.priority = 3;      //优先级3MMWave_Global_Params.task.init = Task_create(MMWave_InitTask, &taskParams, NULL);/* Start BIOS */BIOS_start();return 0;
