[Android6.0][RK3399] PCIe 接口 4G模块 EC20 调试记录

https://blog.csdn.net/hnjztyx/article/details/72495433
S5P4418 android 5.1 EC20 R2.0 PCIE接口调试记录

步骤：
1、使用Firefly的AIO-3399【RK3399】开发板，在Android11下调通加USB底板的移远4G模块EC20。
2、将移远mini-PCIE接口的4G模块EC20接入Firefly的AIO-3399，Android11启动之后不能同构4G上网。也没有/dev/ttyUSB2这个设备节点！
3、使用AIO-3399J的DTS【Android10】替换默认的挖掘机的DTS之后，更新的内核可以让移远的EC20通过4G上网。
4、将AIO-3399J的DTS【Android10】合并/替换到挖掘机的DTS之后，更新的内核也可以让移远的EC20通过4G上网。
步骤：根据经验，将AIO-3399J的DTS文件对应到相应的挖掘机的DTS文件之中。
对于：AIO-3399J 和 挖掘机都有的DTS项目，直接使用 AIO-3399J的DTS项目覆盖挖掘机的DTS项目。
对于只在 AIO-3399J 出现的项目，合并到挖掘机对应文件的最后面。
对于只在挖掘机DTS中的项目不处理！

1、
现在可以确认：问题出在DTS设备树的配置部分了！
现在开始比对AIO-3399J和挖掘机的DTS的异同。
Z:\firefly\rockchip-excavator

rk3399-opp.dtsi
rk3399-sched-energy.dtsi
rk3399-vop-clk-set.dtsi
rk3399.dtsi

干掉同名的文件，差异的文件有：
Z:\firefly\rockchip-excavator
rk3399-excavator-sapphire.dtsi
rk3399-sapphire-excavator-edp-avb.dts
rk3399-sapphire-excavator-edp.dtsi
rk3399-sapphire.dtsi

Z:\firefly\rockchip-firefly

rk3399-firefly-aio.dtsi
rk3399-firefly-core.dtsi
rk3399-firefly-demo.dtsi
rk3399-firefly-port.dtsi

很容易/根据经验/很艰难地比对文件，可以知道：
rk3399-firefly-aio.dts 合并到 rk3399-sapphire-excavator-edp-avb.dts
rk3399-firefly-aio.dtsi 合并到 rk3399-sapphire-excavator-edp.dtsi
rk3399-firefly-core.dtsi 合并到 rk3399-sapphire.dtsi
rk3399-firefly-demo.dtsi  望文生义/根据名字，忽略掉，本文件不处理！
rk3399-firefly-port.dtsi 合并到 rk3399-excavator-sapphire.dtsi

放心，第一次合并/干的时候肯定会出现没有加全/遗漏的问题！
就会出现内核编译不过的问题！那就请根据经验修改吧！

2、等你终于编译通过了，单独更新boot.img之后，就kernel/boot了，但是HDMI显示器黑屏，进不了Android11系统的UI界面！

3、根据经验可能是某一个文件更改之后出现的问题，
很容易/根据经验/很艰难地定位文件，可以知道：
【问题出在这里，整个文件不要合并了！】
rk3399-firefly-aio.dts 合并到 rk3399-sapphire-excavator-edp-avb.dts

【合并一下的3个文件，解决编译的问题！】更新的内核也可以让移远的EC20通过4G上网。
rk3399-firefly-aio.dtsi 合并到 rk3399-sapphire-excavator-edp.dtsi
rk3399-firefly-core.dtsi 合并到 rk3399-sapphire.dtsi
rk3399-firefly-demo.dtsi  望文生义/根据名字，忽略掉，本文件不处理！
rk3399-firefly-port.dtsi 合并到 rk3399-excavator-sapphire.dtsi

4、查找PCIE/PCIE0根据经验更新代码块即可。

        uart0_gpios: uart0-gpios {
            rockchip,pins =
                <2 RK_PC3 RK_FUNC_GPIO &pcfg_pull_none>;
        };
        bt_reset_gpio: bt-reset-gpio {
            rockchip,pins =
                <0 RK_PB1 RK_FUNC_GPIO &pcfg_pull_none>;
        };
        bt_wake_gpio: bt-wake-gpio {
            rockchip,pins =
                <2 RK_PD2 RK_FUNC_GPIO &pcfg_pull_none>;
        };
        bt_irq_gpio: bt-irq-gpio {
            rockchip,pins =
                <0 RK_PA4 RK_FUNC_GPIO &pcfg_pull_down>;
        };
    };
    
    pcie {
        pcie_drv: pcie-drv {
            rockchip,pins = <0 13 RK_FUNC_GPIO &pcfg_pull_none>;
        };

        pcie_3g_drv: pcie-3g-drv {
            rockchip,pins = <2 6 RK_FUNC_GPIO &pcfg_pull_up>;
        };
    };
};

5、虽然改动居多，但是查找PCIE/PCIE0根据经验更新代码块即可。
rk3399-firefly-aio.dtsi 合并到 rk3399-sapphire-excavator-edp.dtsi
    tc358749x: tc358749x@0f {
        compatible = "toshiba,tc358749x";
        reg = <0x0f>;
        //power-gpios = <&gpio2 6 GPIO_ACTIVE_HIGH>;
        power18-gpios = <&gpio2 9 GPIO_ACTIVE_HIGH>;
        power33-gpios = <&gpio2 5 GPIO_ACTIVE_HIGH>;
        csi-ctl-gpios = <&gpio2 10 GPIO_ACTIVE_HIGH>;
        stanby-gpios = <&gpio2 8 GPIO_ACTIVE_HIGH>;
        reset-gpios = <&gpio2 7 GPIO_ACTIVE_HIGH>;
        int-gpios = <&gpio2 12 GPIO_ACTIVE_HIGH>;
        pinctrl-names = "default";
        pinctrl-0 = <&hdmiin_gpios>;
        status = "disabled";
    };

&vopl {
    status = "okay";
    assigned-clocks = <&cru DCLK_VOP1_DIV>;
    assigned-clock-parents = <&cru PLL_VPLL>;
};

&pcie_phy {
    status = "okay";
};

&pcie0 {
    status = "okay";
};

修改为：
&vopl {
    status = "okay";
    assigned-clocks = <&cru DCLK_VOP1_DIV>;
    assigned-clock-parents = <&cru PLL_VPLL>;
};

&vdd_pcie3v3 {
    gpio = <&gpio0 13 GPIO_ACTIVE_HIGH>;  //change with power led
};

&vcc3v3_3g {
    gpio = <&gpio2 6 GPIO_ACTIVE_HIGH>;
};

&pcie_phy {
    status = "okay";
};

&pcie0 {
   ep-gpios = <&gpio4 RK_PD1 GPIO_ACTIVE_HIGH>;
   status = "okay";
};

&rt5651_sound {
    status = "okay";
};

&pinctrl {
    cam0 {
         cif_pwr: cif-pwr {
            rockchip,pins = <1 22 RK_FUNC_GPIO &pcfg_pull_up>;
         };
    };
    
    pcie {
        pcie_drv: pcie-drv {
            rockchip,pins = <0 13 RK_FUNC_GPIO &pcfg_pull_none>;
        };

        pcie_3g_drv: pcie-3g-drv {
            rockchip,pins = <2 6 RK_FUNC_GPIO &pcfg_pull_up>;
        };
    };
    
    lcd-panel {
        lcd_panel_reset: lcd-panel-reset {
            rockchip,pins = <4 RK_PD6 RK_FUNC_GPIO &pcfg_pull_up>;
        };
    };

    hdmiin {
        hdmiin_gpios: hdmiin_gpios {
        rockchip,pins =
                <2 RK_PA5 RK_FUNC_GPIO &pcfg_pull_none>,
                <2 RK_PA6 RK_FUNC_GPIO &pcfg_pull_none>,
                <2 RK_PA7 RK_FUNC_GPIO &pcfg_pull_none>,
                <2 RK_PB0 RK_FUNC_GPIO &pcfg_pull_none>,
                <2 RK_PB1 RK_FUNC_GPIO &pcfg_pull_none>,
                <2 RK_PB4 RK_FUNC_GPIO &pcfg_pull_none>;
        };
    };
};

6、最后很容易/根据经验/很艰难地定位文件，可以知道是这里的问题【电源的配置】：
rk3399-firefly-core.dtsi 合并到 rk3399-sapphire.dtsi
Z:\3TB\76Android11.0\kernel\arch\arm64\boot\dts\rockchip\rk3399-sapphire.dtsi
&i2s2 {
    status = "okay";
};

&io_domains {
    status = "okay";

    bt656-supply = <&vcc_3v0>;
    audio-supply = <&vcca1v8_codec>;
    sdmmc-supply = <&vcc_sdio>;
    gpio1830-supply = <&vcc_3v0>;
};

&pmu_io_domains {
    pmu1830-supply = <&vcc_3v0>;
    status = "okay";
};

修改为：
&i2s2 {
    status = "okay";
};

&io_domains {
    status = "okay";

    bt656-supply = <&vcc1v8_dvp>;        /* bt656_gpio2ab_ms */
    audio-supply = <&vcca1v8_codec>;    /* audio_gpio3d4a_ms */
    //sdmmc-supply = <&vcc_sd>;        /* sdmmc_gpio4b_ms */
    sdmmc-supply = <&vcc_sdio>;
    gpio1830-supply = <&vcc_3v0>;        /* gpio1833_gpio4cd_ms */
};

&pmu_io_domains {
    pmu1830-supply = <&vcc_3v0>;
    status = "okay";
};

7、使用USB底板的EC20能够上网需要修改的部分：
缘起：使用友善之臂的Android11可以让EC20上网，但是同样的修改步骤，Toybrick的Android11不能让EC20上网。
最后确认是selinux的问题！

RK3568 Android12 移远4G模块EM05-CE 调试心得

4、适配Android部分的时候主要是利用了rk已有的4g modem框架，打开BOARD_HAS_RK_4G_MODEM属性，并将librk-ril.so 替换为Quectel的ril库，这样会少走一些弯路。
5、我用的ril库版本为Quectel_Android_RIL_Driver_V3.3.78，这个版本才能适配Android12。之前用过3.3.57和3.3.62版本的库，加载时都会报错：

rk3399添加EC25E/EC20...模组

搞来搞去搞了很久，差点放弃走人的时候，发现竟然是这点事。。。辛酸史如下：
android6.01-----kernel4.4.36-----编译环境ubuntu16.04
一、kernel driver
内核有4种驱动方式，usb serial、CDC ACM、Gobinet、QMI WWAN，本文选用的是usb serial和QMI WWAN两种驱动。

（4）打开dongle功能
/device/rockchip/common/BoardConfig.mk
BOARD_HAVE_DONGLE ?= true

（5）检查
logcat -b radio -v time    //查看log
getprop init.svc.ril-daemon    //检查ril守护进程Runing
cat init.rc | grep ril-daemon    //检查ril-daemon服务是否生效
getenforce         //检查SELinux是否开启，命令关闭
getprop gsm.version.ril-impl  //检查ril版本，出现Quectel_Android_RIL_SR01A41V17,如未出现ril库没有添加上，或者检查phone进程
