ARMmbed / DAPLink 项目
仓库地址 https://github.com/ARMmbed/DAPLink
Arm Mbed 应该属于Arm的机构或者是Arm资助的机构. 常用的 DAPLink 基本上都是从这个项目派生的. 仓库主要是使用 Keil, 对 GCC 的支持是 2020 年才正式合并进来的 #750.

Ubuntu 下使用 GCC Arm 编译
参考说明 How to Build
GCC Arm 工具链
下载地址
环境配置
安装python3
下载 GCC Arm 工具链, 并解压到合适的目录
导出项目, 在项目下创建 virtualenv
$ git clone https://github.com/mbedmicro/DAPLink$ cd DAPLink$ pip install virtualenv$ virtualenv venv
启用虚拟环境(因为要使用progen)
$ source venv/bin/activate
第一次运行(如果后面仓库有更新也需要运行)
(venv) $ pip install -r requirements.txt
编译
方式一
PATH=$PATH:/opt/arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/bin/;python tools/progen_compile.py -t make_gcc_arm --clean -v --parallel stm32f103xb_if
方式二
progen generate -t make_gcc_arm -p stm32f103xb_blPATH=$PATH:/opt/arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/bin/;make -C projectfiles/make_gcc_arm/stm32f103xb_bl
遇到的问题
用 gcc arm 10.3 可以顺利编译, 如果用 gcc arm 11.2 会报 SysTick 错误, 如果用 11.3 或 12.2 编译, 会报这样的错误

需要做以下的修改
- 编辑 vi source/daplink/sdk_stub.c
增加以下内容
__attribute__((weak)) int _write(int file, char *ptr, int len){ (void)file; //int DataIdx; //for (DataIdx = 0; DataIdx < len; DataIdx++) //{ // __io_putchar(*ptr++); //} return len;}__attribute__((weak)) int _read(int file, char *ptr, int len){ (void)file; //int DataIdx; //for (DataIdx = 0; DataIdx < len; DataIdx++) //{ // *ptr++ = __io_getchar(); //} return len;}__attribute__((weak)) int _isatty(int fd){ if (fd >= STDIN_FILENO && fd <= STDERR_FILENO) return 1; errno = EBADF; return 0;}__attribute__((weak)) int _close(int fd){ if (fd >= STDIN_FILENO && fd <= STDERR_FILENO) return 0; errno = EBADF; return -1;}__attribute__((weak)) int _lseek(int fd, int ptr, int dir){ (void)fd; (void)ptr; (void)dir; errno = EBADF; return -1;}
- 修改 records/tools/gcc_arm.yaml
在 ld_flags 下增加 -Wl,--no-warn-rwx-segment
之后就能顺利编译了
