【RK3588 开发笔记——wifi蓝牙调试】_rk3588蓝牙调试

SDIO接口与PCIE接口无线模块二选一，若二者蓝牙共用同一个串口，则需要单独供电，不可同时上电。

SDIO 无线

SDIO 接口Wi-Fi：WL_REG_ON由sdio_pwrseq节点进行管理控制，不需要在wireless-wlan节点下面重复添加WIFI,poweren_gpio配置;

PCIE无线

PCIe配置有两个关键点：
一是对照原理图找到如下三个关键点：
PCIe接口的WiFi基本有两种：贴在板子上模块及M2接口，但它们关键点是一样的：
VBAT/VCC3V3 ：总的3.3V电源，确保正常；
WIFI_REG_ON ：芯片的复位/使能管脚，确保为高电平；
PCIE_PERST_L/PERSTO：芯片PCIe部分的复位管脚，DTS对应的PCIE节点下务必配置正确；
二是根据原理图正确配置Controller及phy。

参考docs\Common\PCIe\Rockchip_Developer_Guide_PCIe_CN.pdf

//Wi-Fi节点配置
wireless_wlan: wireless-wlan {
	compatible = "wlan-platdata";
	wifi_chip_type = "ap6275p";
	... ...
	//配置：WIFI_HOST_WAKE，如果有的话
	WIFI,host_wake_irq = <&gpio0 RK_PA0 GPIO_ACTIVE_HIGH>;
	status = "okay";
};
//添加WIFI_REG_ON的配置
wifi_regon: wifi-regon {
	compatible = "regulator-fixed";
	regulator-name = "wifi_regon";
	regulator-boot-on;
	regulator-min-microvolt = <1800000>;
	regulator-max-microvolt = <1800000>;
	enable-active-high; //LEVEL高有效，如果是低有效改为LOW
	gpio = <&gpioX RK_PXX GPIO_ACTIVE_HIGH>; //修改为对应的GPIO，LEVEL同上
	startup-delay-us = <5000>;
};
//PHY的节点，不同芯片名字不一样，有的叫做&combphy2_psq，实际名称参考上面的三个文档；
&pcieXXphy {
	status = "okay";
};
//控制器节点，具体接到哪个控制器节点
&pcixxx {
	/* 此项是设置 PCIe 接口的 PERST#复位信号；不论是插槽还是
	* 焊贴的设备，请在原理图上找到该引脚，并正确配
	* 置，否则将无法完成链路建立。
	*/
	ep-gpios = <&gpio3 13 GPIO_ACTIVE_HIGH>; //RK3399平台
	reset-gpios = <&gpio4 RK_PA5 GPIO_ACTIVE_HIGH>; //RK356X/3588平台
	/* 下面三个配置是可选项，用于配置PCIe外设的1V8/3V3供电；
	* 是板级针对PCIe外设供电需要控制使能的配置项
	*/
	vpcie3v3-supply = <&vdd_pcie3v3>;
	num-lanes = <4>;
	pinctrl-names = "default";
	pinctrl-0 = <&pcie_clkreqn_cpm>; //无需修改，按照平台默认即可；
	status = "okay";
};

蓝牙配置

/* 蓝牙节点 */
/* 注意下面关于UART的配置：uart4_xfer/uart4_rts/uart4_ctsn

* 应的uart写法，比如uart4_ctsn有些平台的名字为uart4_cts.
*/

导致原因：pcie接口模块与sdio接口模块共用电源、蓝牙开关以及串口，串口发送数据，两个模块同时接收导致数据异常，关闭其中一个模块电源恢复正常。

测试串口

将RX、TX短接，进行回环测试，

在adb root 、adb shell下执行：cat /dev/ttyS6 & echo 123 > /dev/ttyS6
