ESP32-C3使用WIFI_STA例程卡死在初始化(phy_init:)

Postby k_ying » Wed Mar 30, 2022 2:29 am

ESP32-C3使用的是官方MINI模块，但是板子是自制的，前段时间跑通了LVGL很高兴，昨天开始尝试WIFI。
事情最初是这样子的：
1. 使用IDF里的station模式例程做测试发现烧录完Monitor直接输出报错，没有芯片启动log信息。而且网上说辞不一，定位不了问题。
Code: [Select all] [Expand/Collapse]
  1. Exception in thread Thread-2 (_run_outer):
  2. Traceback (most recent call last):
  3.   File "/usr/lib/python3.10/threading.py", line 1009, in _bootstrap_inner
  4.     self.run()
  5.   File "/usr/lib/python3.10/threading.py", line 946, in run
  6.     self._target(*self._args, **self._kwargs)
  7.   File "/home/kying/esp/esp-idf/tools/idf_monitor_base/stoppable_thread.py", line 58, in _run_outer
  8.     self.run()
  9.   File "/home/kying/esp/esp-idf/tools/idf_monitor_base/serial_reader.py", line 51, in run
  10.     self.serial.open()
  11.   File "/home/kying/.espressif/python_env/idf4.4_py3.10_env/lib/python3.10/site-packages/serial/serialposix.py", line 338, in open
  12.     self._update_rts_state()
  13.   File "/home/kying/.espressif/python_env/idf4.4_py3.10_env/lib/python3.10/site-packages/serial/serialposix.py", line 708, in _update_rts_state
  14.     fcntl.ioctl(self.fd, TIOCMBIC, TIOCM_RTS_str)
  15. OSError: [Errno 71] Protocol error

2. 于是开始排查问题，在例程的nvs初始化后、wifi初始化之前加入延迟，烧录后Monitor成功看到BootLoader等log信息。
代码：
Code: [Select all] [Expand/Collapse]
  1. esp_err_t ret = nvs_flash_init();
  2.     if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
  3.       ESP_ERROR_CHECK(nvs_flash_erase());
  4.      ret =  nvs_flash_init();
  5.      }
  6.      ESP_ERROR_CHECK(ret);
  7.  
  8.     ESP_LOGI(TAG, "ESP_WIFI_MODE_STA");
  9.     printf("---------------- WiFi START! -----------------\n");
  10.     vTaskDelay(5000/portTICK_RATE_MS);
  11.     wifi_init_sta();

然后就卡住了，没有像网络教程那样有后面的输出，比如连接WiFi的ssid密码以及是否成功或尝试重连等。而且感觉芯片会卡死，关闭再启动Monitor又会回到不加延迟的报错OSError: [Errno 71] Protocol error，且不可再正常烧录，需要拉低IO9进入下载模式才行。
3. 参考了本论坛中/英板块可能类似的问题，擦除flash、关闭nvs等操作，大多结果都差不多，只不过擦除第一次可能多一句：
W (5634) phy_init: failed to load RF calibration data (0x1102), falling back to full calibration
但后面依旧卡死，没有log输出。起初网络上很多说这句Warnning是供电问题导致的，但我的设计使用的AMS1117-3.3供电理论支持1A MAX且加了10uf+0.1uf电容，我甚至后来拆了稳压芯片使用稳压源供电（USB仅提供Jtag调试）仍然有该行。后来论坛其他帖子和手册看到nvs擦除后就会回到full calibration，所以到头来大概不是供电问题。
目前排查的情况就是这些了，如我有什么疏漏的地方请告知我，有解决的可能思路请尽管提出，十分感谢各位。下一步计划是换一块模块看看情况，以及想请问这个phy init具体的情况，该配置是否可以更换版本，我看网上其他人log输出的版本不一样，会不会是该原因？

用另一块相同设计的备用电路板，焊上另一块新买的C3-MINI模块，烧录相同的代码、正常了 :o 应该只是之前那块射频莫名有问题...

又做了一版硬件，发现其实不是芯片的问题，是WiFi启动后不能用Jtag调试口IO18、IO19吗？我用串口调试才能收到后面的输出...
