https://e2e.ti.com/support/processors-group/processors/f/processors-forum/648324/processor-sdk-am335x-usb-wifi-card-hotplug-error

器件型号：PROCESSOR-SDK-AM335X

我使用了 rt818etv 无线网卡测试、并使用了 SDK (ti-sdk-am335x-evm-07.00.00.00)集成驱动程序、重复热插入后报告了以下错误。

因此、我还在最新的 SDK (ti-processor-sdk-linux-rt-am335x-evm-04.01.00.06)中对其进行了测试、tt 仍会导致内核崩溃

我应该怎么做？

    日志应该是无害的。 内核日志发生后，您是否对网卡有任何功能问题？ 如果不是、则可以忽略日志。 如果您发现任何功能问题、请描述症状并提供任何日志。

    [报价用户="LL shuor"]发生此错误时，终端重复上述错误，网络断开连接。[/quot]

    对于 Processor SDK v4.1.0.6、该错误应仅发生一次、但不会重复发生。 请勿使用 Sitara SDK v7.0进行测试、该版本非常旧、TI 不再提供支持。

    您能否确认 Processor SDK v4.1.0.6是否发生此错误？

    我使用的是 Sitara SDK v7.0、因为 wayland Weston 问题未得到解决(此问题已转交给同事)、我们无法使用 SDK v4.1.0.6、但我将使用 SDK v4.1.0.6对此进行测试
