在github搜到一个在NUCLEO-F429ZI开发板上移植ptpd的example因为和F407差别很小所以就打算用这个demo移植到手头的开发板上。因为目前只需要slave所以只调试了slave。据介绍master好像原作者没有充分测试过。

1.修改ETH引脚
projects/nucleo_ptpd_slave/src/hal_system.c中 HAL_ETH_MspInit 函数里有ETH引脚初始化 根据自己手头板子调整引脚初始化其实可以先用STM32CubeMX生成一个测试工程测试一下板子硬件是好的再移植是最正确的流程。关于ETH硬件测试工程可以参考我之前的博文
(GCC)从零开始的ETH开发--STM32F407ZGTX_我我我只会printf的博客-CSDN博客
这里记得在初始化完成后使用复位引脚复位PHY。还有原工程是F429现在改成F407需要修改头文件hal_system.h中 还有时钟类型需要根据实际修改一般都是外部晶振 2.修改makefile
F429和F407启动文件不同所以需要修改slave工程包含的makefile 其次删除newlib_stubs.c文件否则编译后的固件没办法使用。 还有修改宏定义 还有注意修改ld脚本文件这里我使用的是自己新建的ld文件 其他修改可有可无根据自己情况修改。makefile文件如下

}注意我使用的gcc版本是
gcc version 10.3.1 20210621 (release) (GNU Arm Embedded Toolchain 10.3-2021.08)
如果你是用同样的版本可以直接使用上述makefile否则可能出现编译失败错误。
3.修改串口
串口配置在console.c文件中因为我使用的串口和 USE_STM32F4_DISCOVERY 这个开发板串口相同所以我在上文宏定义的地方直接使用了USE_STM32F4_DISCOVERY宏定义如果你也按上文使用了USE_STM32F4_DISCOVERY宏定义但是串口又不相同请修改 以及中断名称 GCC下重定向printf请添加
int _write (int fd, char *pBuffer, int size)
{for (int i 0; i size; i){if(pBuffer[i] \n)console_putc(\r);console_putc((int)pBuffer[i]);}return size;
}
4.修改报文
注意此处修改只是我为了和电脑运行的ptp4l之间进行测试如果不修改报文ptp4l会认为报文异常。 还有slave和master之间稳定的限幅可以设置的大一点 5.代码编译
至此所有修改完成在slave工程目录下make即可 6.代码运行 ubuntu下使用
sudo ptp4l -E -4 -S -i ens40 -m
-i后跟网卡名称
