dm8127平台，关于wifi模块（RT5370）异常自动卸载后又重新挂载的问题?

1642

问答对人有帮助，内容完整，我也想知道答案 0 您好！我在使用dm8127平台设备进行拷机的过程中，大概拷机5个小时左右就登不了web端（问题复现多次），后来检查发现是wifi模块出现了问题，导致wifi模块自动的卸载后又重新挂载并自动开启了DHCP功能来获取IP和网关，导致wifi的IP和网关改变登不了web端。多次测试发现是wifi驱动代码中检测到一个异常信号，wifi模块保护自动进行了自动卸载然后又加载模块的一个过程。我就想问一下大概是软件驱动问题还是硬件电路问题？谢谢串口打印如下： root@CSUN_IPNC:~# [host] MCFW_IPCBITS: Callback function:App_ipcBitsInCbFxn [host] MCFW_IPCBITS:App_ipcBitsRecvStreamFxn:INFO: periodic print..Bulk In Failed.
