BeagleBone SDIO WIFI pinmux問題

wen ting

Other Parts Discussed in Thread: AM3352

我在BeaglebBone Black( SDK-PROCESSOR2.00.02.11版本 )上使用RTL8723BS的WIFI模塊，ifconfig -a发现没有wlan0设备，ifconfig wlan0 up回應No Such Deivce，我有額外安裝廠商給的rtl8723bs-master Drvier，開機也有init進去，目前感覺是SDIO pin mux有出錯，我是用的是mmc2(軟體為mmc3)，以下為我修改的兩個dts，能幫我看看是否哪裡設定錯了嗎? 感謝。

am335x-bone-common.dtsi檔案有新增的程式碼 :

&am33xx_pinmux {

mmc3_pins: pinmux_mmc3_pins {
               pinctrl-single,pins = <
                       0x44 (PIN_INPUT_PULLUP | MUX_MODE3)     /* gpmc_a1.mmc2_dat0, INPUT_PULLUP | MODE3 */
                       0x48 (PIN_INPUT_PULLUP | MUX_MODE3)     /* gpmc_a2.mmc2_dat1, INPUT_PULLUP | MODE3 */
                       0x4C (PIN_INPUT_PULLUP | MUX_MODE3)     /* gpmc_a3.mmc2_dat2, INPUT_PULLUP | MODE3 */
                       0x78 (PIN_INPUT_PULLUP | MUX_MODE3)     /* gpmc_ben1.mmc2_dat3, INPUT_PULLUP | MODE3 */

                       0x8C (PIN_INPUT_PULLUP | MUX_MODE3)     /* gpmc_clk.mmc2_clk, INPUT_PULLUP | MODE3 */
               >;
       };

}

建议把相关PINMUX寄存器打印出来，有助于定位原因

Probe()函数有执行了么?

能請問什麼是Probe()函數嗎?
似乎沒有执行到類似的函數，我應該到哪裡去設定嗎?感謝。

Probe()就是探针函数

在驱动程序注册的时候，会有一个match的过程，将驱动和设备两个匹配。在匹配的过程中会调用probe()

你好，我遇到了同样的问题，我使用的是wl1835，下面是设备树配置，现象为wl1271_probe无法执行，似乎驱动没匹配上设备，请问该如何处理？

使用是自己的驱动吗

你的環境是使用Ti-SDK嗎? 你上驅動的詳細步驟與過程?
基本上步驟就是改SDIO的Device tree，然後上正確的WiFi驅動就可以了，需要特別注意的是kernel menuconfig下面三個選項有沒有記得on :
[*] cfg80211 – wireless configuration API
[*] cfg80211 wireless extensions compatibility
[*] Generic IEEE 802.11 Networking Stack (mac80211)

你是使用BBB wireless板子嗎或是分別獨立的BBB+wl1835 evm?
如果是後者，BBB+wl1835，記得走線不要過長，小於10cm，以免影響SDIO訊號。

你好。。你能把SDIO的Device tree的正确版本让我参考一下么？

被这个问题困扰了很久。

能否提供您現在用的SoC與SDIO網卡相關型號，以及SDK版號?

建議您先去量測看看SDIO的CMD與CLK信號，我當初的問題後來查出是因為CMD訊號驅動不足，主要原因是PCB上Layout走線過長。
您的SDIO接線不知目前是使用何種連接方式?
若為杜邦線，建議使用5cm長度去測試
若為PCB layout，建議不要超過15cm，且訊號不要跨版
或者可以參考SDIO接口硬體規範，加上上拉電阻增強驅動

希望有幫助到您 Thanks

我使用的是AM3352，内核版本4.1.158，WIFI芯片为beagle core WF111
硬件的走线PCB在5cm左右应该没有问题，并也具备了上拉电阻
我用示波器在CMD与CLK上均看不到信号
我认为是我的Device tree没有写对，导致系统找不到我挂载的wf111驱动程序，无法形成关联。
这是我的device tree配置：
wifi_pins: wifi_pins_default {
pinctrl-single,pins = <
0x44 (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_dat0.mmc0_dat3 */
0x48 (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_dat1.mmc0_dat2 */
0x38 (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_dat2.mmc0_dat1 */
0x3c (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_dat3.mmc0_dat0 */
0x8c (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_clk.mmc0_clk */
0x88 (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_cmd.mmc0_cmd */
/*0x160 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* spi0_cs1.gpio0_6 */
/*0x048 (PIN_INPUT_PULLDOWN | MUX_MODE4) /* MDIO.mmc0_cd */
>;
};

&mmc3 {
status = "okay";
/* vmmc-supply = <&wlan_en_reg>;*/
bus-width = <4>;
pinctrl-names = "default";
pinctrl-0 = <&wifi_pins>;
ti,non-removable;
#address-cells = <1>;
#size-cells = <0>;

unifi: unifi@1 {
compatible = "unifi";
reg = <1>;
/*interrupt-parent = <&gpio3>;
interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;*/
/*ref-clock-frequency = <20000000>; /*38400000*/
};
};

其中unifi为驱动名

我看你的設定應該沒什麼大問題，我猜是Wi-Fi Driver那邊沒掛好
給您參考我最後的設定:
&mmc3 {
dmas = <&edma_xbar 12 0 1
&edma_xbar 13 0 2>;
dma-names = "tx", "rx";
status = "okay";
vmmc-supply = <&vmmcsd_fixed>;
bus-width = <4>;
max-frequency = <25000000>;
pinctrl-names = "default";
pinctrl-0 = <&mmc3_pins >;
ti,non-removable;
ti,needs-special-hs-handling;
cap-power-off-card;
keep-power-in-suspend;

#address-cells= <1>;
#size-cells = <0>;
};

mmc3_pins: pinmux_mmc3_pins {
pinctrl-single,pins = <
0x44 (PIN_INPUT_PULLUP | MUX_MODE3)
0x48 (PIN_INPUT_PULLUP | MUX_MODE3)
0x4C (PIN_INPUT_PULLUP | MUX_MODE3)
0x78 (PIN_INPUT_PULLUP | MUX_MODE3)
0x88 (PIN_INPUT_PULLUP | MUX_MODE3)
0x8C (PIN_INPUT_PULLUP | MUX_MODE3)
>;
};

建議您檢查看看$(Kernel)/deivers/net/wireless目錄下有沒有對應的WF111驅動

以及Kernel的menuconfig是否enable相關功能如下:
Networking support ->
wireless ->
[*] cfg80211 – wireless configuration API
[*] cfg80211 wireless extensions compatibility
[*] Generic IEEE 802.11 Networking Stack (mac80211)
Device Drivers ->
Network device support->
[*] Wireless LAN->
[*] Realtek 8189F SDIO WiFi

這是我使用 Realtek RTL8723BS網卡的設定，WF111我沒使用過，或許有需許差異可能要查看看相關手冊

我尝试使用了你刚才发的设备树配置，仍然没有生效，已经找不到问题了。
内核配置我检查过与你所说的相符
驱动我可以确定已经挂载好了，在/sys/bus/sdio/drivers目录下有unifi项目，而在/sys/bus/sdio/devices目录下找不到设备
wf111芯片手册告诉我是sdio驱动缺失
但SD卡是可以使用的，软件问题只能是设备树没有匹配
也可能硬件还有问题没有被发现。
我可能要放弃这块芯片了
谢谢你的帮助
