Where did you get the DHD driver for kernel 4.15?

有前面驱动load时候的完整log 吗? SDIO 接口是否已经工作正常。

如果KSO 这部分功能有异常, 可以考虑将dhdsdio_clk_kso_enab skip掉来测试下看是否可以正常跑起来。

没有。用逻辑分析仪抓了下,看上去是SDIO通信问题,前几天想找平台原厂(AT91SAMA5D27)帮忙看下,一直没联系上。
请问你们以前遇到过类似问题吗?

你有办法在其他稳定的平台上用相同的dhd+模组 来做测试吗? 这样可以排除一些问题。

insmod没有问题,并且可以通过ifconfig -a 查看到wlan0节点,执行ifconfig wlan0 up时出现上面问题!
