Wi-Fi Bluetooth for Linux

Hi Sir,

我在调试43455的时候,在加载FW出现error,导致DHD 加载失败。

我使用的环境是IMX.8的平台,arm64,Linux4.18,DHD版本125.15~125.19都有验证过,海华197(43438),288(43362),256(43455)EVK,其中197,288都可以正常工作,256在以上所有版本驱动都出现FW加载失败的问题,理论上来说43438与43455共用同一版驱动没有问题的,也怀疑过可能是256EVK本身的问题,用FMAC验证256EVK是可以正常工作的,所以现在比较疑惑,请帮忙分析下,谢谢。

以下是256加载驱动时的dmesg log,其中一份是通过256EVK的SD口供电,另一份是256EVK的USB口供电。

SD口供电dmesg:

Hi Zhengbao,

我更换了kernel版本3.14验证,256可以正常run起来。

所以,目前看起来在4.14.98的kernel上出现异常,我今天把256EVK寄给你,帮忙看下是否可以提供对应的patch。

BR,

Leo

有加进去的,43438可以正常工作,43455还是同样的错误。
