const功能接口注册问题

}
REGISTER_CMD(get_time, cmd_get_time, get_time);// __GUNC__环境需要实现功能注册必须建表。
// 屏蔽原先接口
#define REGISTER_CMD(...)
// 新建关联表

};USB_OTG问题
移植是需要删除一下文件
usbh_msc_fatfs.c
usb_conf_template.h特殊函数替换

}IAP相关问题
bootloader工程flash最好也修改限制自身的大小限制
MEMORY
{RAM (xrw) : ORIGIN 0x20000000, LENGTH 128KCCMRAM (xrw) : ORIGIN 0x10000000, LENGTH 64KFLASH (rx) : ORIGIN 0x08000000, LENGTH 64K
}bootloader跳转问题
// __GUNC__环境编译后得到的hex及bin文件无法满足以下条件
if ((tmp 0x2FFE0000) 0x20000000) // 检查栈顶地址是否合法.
目前没有找到更好的办法做注释处理。
u32 tmp 0;
s8 iap_load_app(u32 appxaddr)
{// if ((tmp 0x2FFE0000) 0x20000000) // 检查栈顶地址是否合法.{jump2app (iapfun) * (vu32 *)(appxaddr 4); // 用户代码区第二个字为程序开始地址(复位地址)__set_MSP(appxaddr); /* 设置栈顶地址 */// MSR_MSP(*(vu32 *)appxaddr); // 初始化APP堆栈指针(用户代码区的第一个字用于存放栈顶地址)jump2app(); // 跳转到APP.}return 1;
}application需要修改三处
// 第一处 LD文件
MEMORY

}// 第二处 makefile文件
// 增加USER_VECT_TAB_ADDRESS宏定义

下载可以借用sergger - jlink驱动在makefile文件添加如下

1驱动的安装位置
2JKS_DIR定义的位置这个直接索引编译后的hex文件
浮点数打印及格式化问题
makefile文件中去除-specsnano.specs
# LDFLAGS -specsnano.specs注意去除后编译大小将增加40K代码空间
关于VSCODE编写代码高亮、索引、宏定义关联问题
在.vscode文件夹下根据需要添加目录索引及相关宏定义即可 4. 关于二次开发
二次开发新建的文件存放于user对应的目录下即可无需修改makefile文件。
4. 编译、下载、清除
