TRNG DA14531

如果我重新加载并启动固件，我总是得到相同的输出。在我看来这是不应该的。

代码:

Void user_app_init(Void) {arch_printf("\r\n\r\nuser_app_init\r\n");//使用从TRNG获取的随机位初始化随机数生成器种子init_rand_seed_from_trng();//用trng随机数初始化标准c rand()函数//测试:通过随机数生成器循环测试随机数生成器…(uint8_t我= 0;我< 10;i++){//获得16字节随机数字的AES-128键(uint8_t i=0;我< ENC_DATA_LEN;i++){generated_challenge[i] = rand()%0xFF;} user_app_format_data("CHALLENGE"， generated_challenge, 16); } app_param_update_request_timer_used = EASY_TIMER_INVALID_TIMER; // Initialize Manufacturer Specific Data mnf_data_init(); // Initialize Advertising and Scan Response Data memcpy(stored_adv_data, USER_ADVERTISE_DATA, USER_ADVERTISE_DATA_LEN); stored_adv_data_len = USER_ADVERTISE_DATA_LEN; memcpy(stored_scan_rsp_data, USER_ADVERTISE_SCAN_RESPONSE_DATA, USER_ADVERTISE_SCAN_RESPONSE_DATA_LEN); stored_scan_rsp_data_len = USER_ADVERTISE_SCAN_RESPONSE_DATA_LEN; default_app_on_init(); }

控制台输出:
