| Firefly,RK3568的开发板，Android11，linux4.19，原本开发板上是正基的AP6275S的WiFi模组，按照原本代码里的dtsi配置，WiFi模组是可以正常工作的 现在我把开发板上的AP6275S模组换成RTL8822CS模组，这两个模组是pin to pin的，所以我个人认为是不需要修改dtsi的 但是现在的情况是，RTL8822CS模组在开发板上电后，测量这三个关键脚的电压，vbat:3.3v,vddio:1.8v,WL_REG_ON:0v，所以就是WiFi的使能脚没有拉上去，因此模块没有被正确识别到 然后我把dtsi里面的reset-gpios = <&gpio3 RK_PD5 GPIO_ACTIVE_LOW>;屏蔽掉之后，WL_REG_ON变成1.8v，说明WiFi的使能脚被拉上去了，按理说这种情况下WiFi模组是可以被识别到sdio节点了，但是我cat /sys/bus/sdio/devices，仍然为空，没有识别到节点 正常可以识别到的AP6275S模组，开发板上电过程过会有这样的打印：[ 1.298662] mmc3: new ultra high speed SDR104 SDIO card at address 0001 换成RTL8822CS模组之后，有这样的报错：[ 1.013139] mmc3 mmc_send_io_op_cond err: -110 另外，这是设备树中关于WiFi模组部分的定义 rk3568-firefly-roc-pc.dtsi： &sdio_pwrseq { status = "okay"; reset-gpios = <&gpio3 RK_PD5 GPIO_ACTIVE_LOW>; post-power-on-delay-ms = <100>; }; /* used for wifi */ &sdmmc2 { status = "okay"; }; &wireless_wlan { wifi_chip_type = "ap6275s"; status = "okay"; }; rk3568-firefly-port.dtsi： sdio_pwrseq: sdio-pwrseq { compatible = "mmc-pwrseq-simple"; clocks = <&rk809 1>; clock-names = "ext_clock"; pinctrl-names = "default"; pinctrl-0 = <&wifi_enable_h>; /* * On the module itself this is one of these (depending * on the actual card populated): * - SDIO_RESET_L_WL_REG_ON * - PDN (power down when low) */ post-power-on-delay-ms = <200>; reset-gpios = <&gpio3 RK_PD5 GPIO_ACTIVE_LOW>; }; wireless_wlan: wireless-wlan { compatible = "wlan-platdata"; rockchip,grf = <&grf>; wifi_chip_type = "ap6398s"; pinctrl-names = "default"; pinctrl-0 = <&wifi_host_wake_irq>; WIFI,host_wake_irq = <&gpio3 RK_PD4 GPIO_ACTIVE_HIGH>; status = "disabled"; }; &sdmmc2 { max-frequency = <150000000>; supports-sdio; bus-width = <4>; disable-wp; cap-sd-highspeed; cap-sdio-irq; keep-power-in-suspend; pinctrl-names = "default"; pinctrl-0 = <&sdmmc2m0_bus4 &sdmmc2m0_cmd &sdmmc2m0_clk>; sd-uhs-sdr104; mmc-pwrseq = <&sdio_pwrseq>; non-removable; status = "disabled"; }; 这是什么原因导致，以及我该怎么定位问题点，怎么解决？ 127|:/ # dmesg | grep mmc [ 0.000000] Kernel command line: storagemedia=emmc androidboot.storagemedia=emmc androidboot.mode=normal androidboot.dtb_idx=0 androidboot.dtbo_idx=0 androidboot.verifiedbootstate=orange androidboot.serialno=a71618cb25982e2f console=ttyFIQ0 androidboot.baseband=N/A androidboot.wificountrycode=CN androidboot.veritymode=enforcing androidboot.hardware=rk30board androidboot.console=ttyFIQ0 androidboot.verifiedbootstate=orange firmware_class.path=/vendor/etc/firmware init=/init rootwait ro loop.max_part=7 androidboot.selinux=permissive buildvariant=userdebug earlycon=uart8250,mmio32,0xfe660000 androidboot.boot_devices=fe310000.sdhci,usbhost/fd000000.dwc3/xhci-hcd.5.auto,fd880000.usb,fd800000.usb,fe2b0000.dwmmc,fc800000.sata,3c0800000.pcie,3c0000000.pcie [ 0.878005] dwmmc_rockchip fe000000.dwmmc: IDMAC supports 32-bit address mode.
