Arm 如何将DFU支持添加到u-boot?
我试图将DFU支持添加到我在项目中使用的u-boot中,因为我发现它没有启用DFU支持 我使用的是飞思卡尔u-boot(从git://git.freescale.com/imx/uboot-imx.git)我检查了标签“rel_imx_4.1.15_1.1.0_ga”,这是我需要处理的标签 问题是,通过u-boot文档,我可以看到必须启用DFU。我在.h文件中添加了以下内容Arm 如何将DFU支持添加到u-boot?,arm,usb,u-boot,dfu,Arm,Usb,U Boot,Dfu,我试图将DFU支持添加到我在项目中使用的u-boot中,因为我发现它没有启用DFU支持 我使用的是飞思卡尔u-boot(从git://git.freescale.com/imx/uboot-imx.git)我检查了标签“rel_imx_4.1.15_1.1.0_ga”,这是我需要处理的标签 问题是,通过u-boot文档,我可以看到必须启用DFU。我在.h文件中添加了以下内容 #define CONFIG_USB_FUNCTION_DFU #define CONFIG_CMD_DFU #defin

但我得到了以下错误:

我注意到,如果我从.h文件中删除#define CONFIG_CMD_DFU,它编译得很好,但如果我在u-boot shell中输入=>DFU,它会显示:
Unknown command 'dfu' - try 'help'
所以问题是*你知道我还需要添加什么才能在我使用的u-boot中启用DFU吗
谢谢

基本上,链接问题可以通过下一种方式解决。要找出缺少的定义,您可以查找缺少的函数的实现位置,然后查找Makefile
启用了相应的源文件以进行构建的位置,并从该Makefile
中确定要定义的选项,因此,相应的对象文件被构建,并且在链接阶段所需的功能已经就位
