+## 板级系统移植 + +### SoC芯片平台HDF驱动移植 + +驱动适配相关文件放置在`device/soc/st/common/platform`中，所有的驱动都是通过`HDF`机制加载，本章节以`gpio`为例进行详细说明。 + +#### GPIO驱动适配 + + +1. 在`//device/soc/st/common/platform/gpio/BUILD.gn`文件中，描述了stm32mp1xx `gpio`驱动的编译适配。如下： + + ``` + module_switch = defined(LOSCFG_DRIVERS_HDF_PLATFORM_GPIO) --- 如果打开HDF的GPIO配置开关，才进行如下编译。 + module_name = get_path_info(rebase_path("."), "name") + + hdf_driver("hdf_gpio") { + sources = [ + "stm32mp1_gpio.c", ---gpio驱动源文件。 + ] + include_dirs = [ ---依赖的.h路径。 + "." , + "../stm32mp1xx_hal/STM32MP1xx_HAL_Driver/Inc", + ] + } + ``` + +2. 在`//device/soc/st/common/platform/gpio/stm32mp1_gpio.c`文件中，描述了stm32mp1xx `gpio`驱动的源码适配。 +首先，按照`OpenHarmony`的`HDF`驱动框架加载驱动基本适配框架，如下： + + ``` + struct HdfDriverEntry g_GpioDriverEntry = { + .moduleVersion = 1, + .moduleName = "HDF_PLATFORM_GPIO", + .Bind = GpioDriverBind, + .Init = GpioDriverInit, + .Release = GpioDriverRelease, + }; + HDF_INIT(g_GpioDriverEntry); --- 通过HDF_INIT 加载GPIO驱动。 + ``` +3. 在//device/soc/st/stm32mp1xx/sdk_liteos/hdf_config/gpio中添加gpio硬件描述信息文件gpio_config.hcs,在该文件中添加驱动私有配置信息。 + ``` + root { + platform { + gpio_config { + controller_0x50002000 { + match_attr = "st_stm32mp1_gpio"; + groupNum = 11; + bitNum = 16; + gpioRegBase = 0x50002000; + gpioRegStep = 0x1000; + irqRegBase = 0x5000D000; + irqRegStep = 0x400; + } + } + } + } + ``` +4. 配置产品加载驱动，产品的所有设备信息被定义在源码文件//vendor/bearpi/bearpi_hm_micro/hdf_config/device_info/device_info.hcs中。 + + 平台驱动请添加到platform的host中。 + + > ![icon-note.gif](public_sys-resources/icon-note.gif) **说明：** + > moduleName要与驱动文件中定义的相同，deviceMatchAttr要与驱动私有配置信息文件gpio_config.hcs中定义match_attr的相同。 + + + ``` + root { + ... + platform :: host { + device_gpio :: device { + device0 :: deviceNode { + policy = 2; + priority = 10; + permission = 0644; + moduleName = "HDF_PLATFORM_GPIO_MANAGER"; + serviceName = "HDF_PLATFORM_GPIO_MANAGER"; + } + device1 :: deviceNode { + policy = 0; + priority = 10; + permission = 0644; + moduleName = "HDF_PLATFORM_GPIO"; + serviceName = "HDF_PLATFORM_GPIO"; + deviceMatchAttr = "st_stm32mp1_gpio"; + } + } + } + } + ``` +5. 完善驱动代码，gpio_config.hcs的配置信息会在GpioDriverInit中加载。 + ``` + static int32_t GpioDriverInit(struct HdfDeviceObject *device) + { + + int32_t ret; + struct Mp1xxGpioCntlr *stm32gpio = &g_Mp1xxGpioCntlr; + + dprintf("%s: Enter", __func__); + if (device == NULL || device->property == NULL) { + HDF_LOGE("%s: device or property NULL!", __func__); + return HDF_ERR_INVALID_OBJECT; + } + //获取属性数据 + ret = Mp1xxGpioReadDrs(stm32gpio, device->property); + if (ret != HDF_SUCCESS) { + HDF_LOGE("%s: get gpio device resource fail:%d", __func__, ret); + return ret; + } + ... + } + ``` + +### OpenHarmony子系统适配 + +`OpenHarmony`子系统适配只需要在`config.json`中增加对应子系统和部件，这样编译系统会将该部件纳入编译目标中。 + +#### 启动恢复子系统适配 + +启动恢复子系统需要适配`bootstrap_lite`、`syspara_lite`、`appspawn_lite`、`init_lite`四个部件。请在`vendor/bearpi/bearpi_hm_micro/config.json`中新增对应的配置选项。 + +``` + { + "subsystem": "startup", + "components": [ + {
