本人习惯于linux下做开发，平时的工作流程是vim写代码，make/cmake等工具配置gcc/clang工具链编译，uboot或openocd/pyocd烧录。顺着【AT-START-F405测评】linux下pyocd+cmake环境搭建并点灯+printf uart输出组建开发环境已经非常方便，下面说说APM32f411V特别的地方或者说需要在已有linux开发环境基础上再做什么即可搭建用于APM32F411V的开发环境。
pyocd的适用于APM32F411V的pack的安装
pyocd pack find apm32f411
0000716 W No matching devices. Please make sure the pack index is up to date. [pack_cmd]
在SDK解压top目录中写一份pyocd.yaml告诉pyocd到哪里找pack文件：
pack:
- ~/.local/share/cmsis-pack-manager/apm32/Geehy.APM32F4xx_DFP.1.0.4.pack
pyocd显示lockup，猜测大概率是由于板子未烧录任何固件导致的，先停下cpu打印下cpu寄存器看看
看看lr、rN、pc和xpsr这些寄存器的值基本上肯定是板子默认没固件的。不过这也说明pyocd可以和板子交互了
Makefile模板的编写
这次咱们选直接写Makefile。观察sdk目录，可以发现：驱动都在Libraries/APM32F4xx_StdPeriphDriver/目录中，Boards/Board_APM32F411_TINY/是板级资源定义和适配，而Libraries/Device/Geehy/APM32F4xx/Source/gcc目录是启动汇编代码和ld脚本，Examples目录是示例代码。这次咱们就以Examples/GPIO/GPIO_Toggle/为基础来点灯吧。
有了以上观察后书写完整Makefile如下：

编译过程发现sdk的一些问题
1.源码中apm32f4xx_sdio.h写成了apm32f4Xx_sdio.h，apm32f4xx_rcm.h写成了apm32f4Xx_rcm.h
对于区分文件大小写的文件系统来说编译会报错，修正补丁如下:

编译&烧录
make即可编译非常方便，烧录用如下命令：
pyocd load -e sector -t apm32f411ve build/apm32f411.bin
