Hi

  1. 软件环境：jp5.0.2

  2. 硬件环境：
    a. xaiver nx TF card,无cd检测信号，不支持热拔插。
    b. TF卡供应是外部3.3V供电，拉死。

  3. 设备树添加如下：

sdmmc3: sdhci@3440000 {
320         mmc-ocr-mask = <0x0>;
321         //cd-inverted;
322         //cd-gpios = <&tegra_main_gpio TEGRA194_MAIN_GPIO(Q, 2) 0>;
323         //nvidia,cd-wakeup-capable;
324         mmc-ocr-mask = <0>;
325         //cd-inverted;
326         non-removable;
327         vmmc-supply = <&p3668_vdd_sdmmc3_sw>;
328         status = "okay";
329     };


   4. 日志如下

   5. 问题
  请问这个是什么问题？
2

請在這個forum搜尋sdmmc3有關連的topic.

4

您好！

  操作方法，我也是按某些论坛上说的去做的。
5

那請問你的always-on 加在哪？

6

always-on是必需要加的对吧？这个是针对sd电源部分的？像我这边无cd脚的是需要加？

7

您说的是设备树的这个部分吗？
nvidia,vqmmc-always-on;

8

對. nvidia,vmmc-always-on是針對電源的部份. 當然你的vmmc-supply那個regulator也要是always-on的設定.

cd-gpio是card detection用的 沒有要用hotplug的話就不需要.

nvidia/platform/t19x/jakku/kernel-dts/common/tegra194-p3668-common.dtsi

sdmmc3: sdhci@3440000 {
320 mmc-ocr-mask = <0x0>;
321 //cd-inverted;
322 //cd-gpios = <&tegra_main_gpio TEGRA194_MAIN_GPIO(Q, 2) 0>;
323 //nvidia,cd-wakeup-capable;

325 nvidia,vqmmc-always-on;
326 //cd-inverted;
327 non-removable;
328 vmmc-supply = <&p3668_vdd_sdmmc3_sw>;
329 status = “okay”;
330 };

nvidia/platform/t19x/jakku/kernel-dts/common/tegra194-fixed-regulator-p3668.dtsi

p3668_vdd_sdmmc3_sw: regulator@103 {
39 compatible = “regulator-fixed”;
40 reg = <103>;
41 regulator-name = “vdd-sdmmc3-sw”;
42 regulator-min-microvolt = <3300000>;
43 regulator-max-microvolt = <3300000>;
44 regulator-always-on;
45 //gpio = <&tegra_main_gpio TEGRA194_AON_GPIO(CC, 0) 0>;
46 //enable-active-high;
47 };

设备树这么设定，结果还是一样的

nvidia,vqmmc-always-on 跟 nvidia,vmmc-always-on是兩個不同property.

11

sdmmc3: sdhci@3440000 {
320 mmc-ocr-mask = <0x0>;
321 //cd-inverted;
322 //cd-gpios = <&tegra_main_gpio TEGRA194_MAIN_GPIO(Q, 2) 0>;
323 //nvidia,cd-wakeup-capable;
324 mmc-ocr-mask = <0>;
325 nvidia,vqmmc-always-on;
326 nvidia,vmmc-always-on;
327 //cd-inverted;
328 non-removable;
329 vmmc-supply = <&p3668_vdd_sdmmc3_sw>;
330 status = “okay”;
331 };

加了后目测是一样的结果

12

please remove nvidia,vqmmc-always-on.

13

please also try to use jetpack4 to validate the hardware first.

14

确定是硬件问题了，谢谢
