Log日志：wifi.zip

3568的底板是我们根据官方文件自己设计的。
wifi模组换成了wilc1000, wifi_rst高电平有效
目前现象是启动后无法发现sdio设备, 日志有报错

mmc3 mmc_send_io_op_cond err: -110

硬件组有测量电压是正常的
请帮忙分析一下可能是什么原因？

wilc1000 要打开对应驱动 CONFIG_WILC1000，dts 配置也不能套用 bcmdhd 模组的

3

即使不加载驱动， 只要WIFI_REG_ON（我们原理图上标注的WIFI_RST）拉高， sdio总线上也应该发现设备吧?
目前我们的情况是 /sys/bus/sdio/devices/ 下面没有设备

4

目前能识别了，软件上主要有两点：

  1. pmu_io_domains 修改电压3v3
vccio6-supply = <&vcc_3v3>;
  1. sdio_pwrseq 配置 GPIO_ACTIVE_LOW
reset-gpios = <&gpio3 RK_PD5 GPIO_ACTIVE_LOW>;

这个跟使能状态恰好是相反

同时硬件同事也修改了部分电阻

5

识别还是有一点问题，之前mmc加了很多打印日志，去掉打印后就不识别了
但是 sdmmc2 中降低频率，就会识别成功

&sdmmc2 {
    // max-frequency = <150000000>;
	max-frequency = <100000000>;
    status = "okay";

加载驱动也会报错
