上一篇写到make menuconfig报错，继续开整。
make menuconfig需要/device/soc/*下面有对应的Kconfig文件。
直接去gitee下载stm32的配置文件拿来参考用。
先提取Kconfig文件，后面再添加其它文件。https://gitee.com/openharmony/device_soc_st/tree/OpenHarmony-v3.2-Beta5/
https://gitee.com/openharmony/device_soc_st/tree/OpenHarmony-v3.2-Beta5/
soc下的目录结构如下：
└── soc└── st├── Kconfig.liteos_m.defconfig├── Kconfig.liteos_m.series├── Kconfig.liteos_m.soc└── stm32f4xx├── Kconfig.liteos_m.defconfig.series├── Kconfig.liteos_m.defconfig.stm32f4xx├── Kconfig.liteos_m.series└── Kconfig.liteos_m.soc
Kconfig.liteos_m.soc会在菜单里添加st这个SOC_COMPANY
还会扫描子目录下的Kconfig.liteos_m.soc，
在stm32f4xx子目录下面的这个文件又向菜单添加SOC_STM32F407
Kconfig.liteos_m.series扫描子目录下的同名文件，
在stm32f4xx子目录里的这个文件又向菜单添加SOC_SERIES_STM32F4xx
再次测试make menuconfig还是会报错：
warning: <choice> (defined at arch/arm/Kconfig:34) defined with type unknown根据错误提示并找不到问题在哪，
最后发现Makefile需要/vendor/demo/hello/kernel_configs/debug.config文件，空文件就行。
进入Platform选择 Soc和stm32f407。
Compat菜单下，选择newlibc
配置完菜单后，配置保存在.config，并生成config.h文件，
同时还会向/vendor/demo/hello/kernel_configs/debug.config写入一部分配置内容。
再次编译看看报什么错：
[OHOS INFO] ERROR at //kernel/liteos_m/BUILD.gn:140:18: Unable to load "/home/openharmony/device/board/demo/BUILD.gn".根据错误，添加BUILD.gn
# /device/board/demo/BUILD.gn
# https://kerndev.blog.csdn.net/import("//kernel/liteos_m/liteos.gni")
module_name = get_path_info(rebase_path("."), "name")
module_group(module_name) {modules = [ "demo_board" ]
}
再次测试，继续根据错误提示，添加以下文件：
/home/openharmony/device/soc/st/BUILD.gn
/home/openharmony/device/soc/st/stm32f4xx/BUILD.gn
/home/openharmony/device/board/demo/demo_board/BUILD.gn
/home/openharmony/vendor/demo/hello/BUILD.gn
/home/openharmony/device/soc/st/stm32f4xx/sdk/BUILD.gn
/home/openharmony/device/soc/st/stm32f4xx/sdk/Drivers
/home/openharmony/device/soc/st/stm32f4xx/sdk/hals然后再次编译错误是：
[OHOS ERROR] ../../../device/soc/st/stm32f4xx/sdk/Drivers/STM32F4xx_HAL_Driver/Src/stm32f4xx_hal_i2c.c:302:10: fatal error: stm32f4xx_hal.h: No such file or directory
[OHOS ERROR] 302 | #include "stm32f4xx_hal.h"
[OHOS ERROR] | ^~~~~~~~~~~~~~~~~
[OHOS ERROR] compilation terminated.这个问题就是BUILD.gn里面没有正确配置include的路径。
打开bsp/BUILD.gn抄一段config()：
config("public") {defines = ["STM32F407xx","STM32F40_41xxx",]include_dirs = ["include","//device/soc/st/stm32f4xx/sdk/Core/Inc","//device/soc/st/stm32f4xx/sdk/Drivers/STM32F4xx_HAL_Driver/Inc","//device/soc/st/stm32f4xx/sdk/Drivers/CMSIS/Device/ST/STM32F4xx/Include","//foundation/systemabilitymgr/samgr_lite/interfaces/kits/samgr",]ldflags = ["-Wl,-T" + rebase_path("ld/STM32F407IG_FLASH.ld"),"-Wl,-u_printf_float",]libs = ["c","m","nosys",]
}这里面有defines预定义2个宏，include_dirs添加头文件路径，
ldflags定义链接脚本路径，libs添加要链接的基本库。
再次编译报错，还要添加/device/demo/demo_board/liteos_m/bsp/include/target_config.h文件。
[OHOS ERROR] ../../../kernel/liteos_m/kernel/include/los_config.h:40:10: fatal error: target_config.h: No such file or directory
[OHOS ERROR] 40 | #include "target_config.h"
[OHOS ERROR] | ^~~~~~~~~~~~~~~~~
[OHOS ERROR] compilation terminated.再次编译报错：bool没定义，这个问题就不是我们的配置问题了，
把源码里的bool改为int，或者在源码内#include <stdbool.h>
[OHOS ERROR] ../../../kernel/liteos_m/components/fs/vfs/vfs_fs.c:214:43: error: unknown type name 'bool'
[OHOS ERROR] 214 | static int VfsPathCheck(const char *path, bool isFile)再次编译找不到STM32F407IG_FLASH.ld文件，按提示添加这个文件。
最后再次编译通过：
