    CYW43438 DHD Driver error

    YiLi_4742921

      Hi ,

       

      我使用的平台是IMX8,海华197模组,目前在调试WiFi的时候,驱动下载FW,NVRAM都是可以的,但是会卡在dhdsdio_htclk,请帮忙分析下,是什么原因导致的,谢谢。

      完整的log如下:

          Hi Leo:

           

            Which version of the kernel are you using now on imx8 ?   and is the imx release having a default bcmdhd release ?

            Hi Zhengbao,

             

            Kernel是4.14,我使用的DHD是15版本的,kernel里面有默认的bcmdhd。

            我现在是在IMX8开发板上面调试的,IMX8板子上面硬件上默认接的是AMPAK的模组,与SD卡共用一组SDIO,我现在是通过SD卡外接海华197模组验证DHD driver。

             

             

            BR,

              default DHD 可以跑起来吗? 我看下是否有针对imx的dhd的patch。

                Hi Zhengbao,

                 

                default DHD是可以跑起来的,我打包放在附件了,你看下。

                      Hi Zhengbao,

                       

                      太棒了,打上你给patch,目前可以生成interface了。完整的log如下,请帮忙看下这样部分error是否有影响。

                        这些fail 没有影响的,只是firmware 不支持这些功能。
