          我跟到这个函数后在注册微信图片_20230518094403.png
          这个函数根本没有执行 那要是wl_regon配置错了 也会出现这个现象吗

              @yuhudnehao 这个问题表示SDIO通讯失败,有这些可能:

              1. 检查各路电源电压是否正确
              2. 检测模组的各个reset是否有被正确拉高,wl_reg_on, bt_rst
              3. 检查32K时钟是否正常
              4. 检查SDIO各个IO是否有上拉电阻
              5. 检查SDIO是否进行了扫卡
              6. 更换芯片或者样机进行测试
