一、基本信息
1.模块：ESP32-WROOM-32X-TestBoard v1.1(ESP32-WROOM-32U)
2.使用例子:
例子1：/home/tony/esp/esp-idf/examples/wifi/scan
例子2：/home/tony/esp/esp-idf/examples/wifi/smart_config
例子3：/home/tony/esp/esp-idf/examples/wifi/power_save
3.使用menuconfig配置freertos
二、问题

为什么，试了3个例子，都是同样问题，出现：
Base MAC address form BLK0 of EFUSE CRC error， efuse_crc = 0x23; calc_crc = 0xf5
abort() was called at PC 0x400d1a13 on core 0
烦请帮忙提供解决办法，谢谢。

你是使用的小米的模组吗？

需要确认模组来源，方便的话请提供一下照片。
为了能正常使用板子的其他功能，暂时的 workaround 为使用用户侧的 mac，可以在 app_main 的开始添加以下代码：
Code: Select all
uint8_t mac[6] = {0x12, 0x34, 0x56, 0x78, 0x90};
esp_base_mac_addr_set(mac);

我用小米模块ESP-WROOM-32x-Testboardv1.1,板载ESP-WROOM-32D模组，用flash_download_tool_v3.8.5,烧写helloworld程序，
报错[2020-08-14 17:52:09,335][ESP8266Loader_spi[1]][espDownloader.py][line:562][ERROR]: ESP32 Chip efuse check error esp_check_mac_and_efuse.

这是什么情况呢？

我的小米模组 esp-wroom-32d 也是同样的问题。

Code: Select all
//1
esp_netif_init();
esp_event_loop_create_default();
esp_netif_create_default_wifi_ap();
wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
esp_wifi_init(&cfg);
esp_event_handler_instance_register(WIFI_EVENT,
ESP_EVENT_ANY_ID,
&wifi_event_handler,
NULL,
NULL);
//2
esp_wifi_set_mode(WIFI_MODE_AP);
wifi_config_t wifi_config = {
.ap = {
.ssid = EXAMPLE_ESP_WIFI_SSID,
.ssid_len = strlen(EXAMPLE_ESP_WIFI_SSID),
.ssid_hidden = 0,
.channel = EXAMPLE_ESP_WIFI_CHANNEL,
.password = EXAMPLE_ESP_WIFI_PASS,
.max_connection = EXAMPLE_MAX_STA_CONN,
.authmode = WIFI_AUTH_WPA_WPA2_PSK},
};
esp_wifi_set_config(ESP_IF_WIFI_AP, &wifi_config);
esp_wifi_start();
我把官方的例子换成了这个，不会报错了，但是手机搜索不到ssid。

感觉这个应该还是内部出错了，只是没有报出来而已。
用espefuse 工具查出来mac
Code: Select all
espefuse.py get_custom_mac -p /dev/ttyS3Connecting........_____..
Detecting chip type... ESP32
espefuse.py v3.0
Custom MAC Address version 103: 00:00:00:07:8c:91 (CRC 0x00 invalid - calculated 0x57)
但是芯片上标记的mac 地址是04:cf:8c:21:80:63
我碰到的错误
Code: Select all
I (633) wifi:wifi driver task: 3ffbab54, prio:23, stack:6656, core=0
