ARMmbed / DAPLink 專案
倉庫地址 https://github.com/ARMmbed/DAPLink
Arm Mbed 應該屬于Arm的機構或者是Arm資助的機構. 常用的 DAPLink 基本上都是從這個專案派生的. 倉庫主要是使用 Keil, 對 GCC 的支持是 2020 年才正式合并進來的 #750.

Ubuntu 下使用 GCC Arm 編譯
參考說明 How to Build
GCC Arm 工具鏈
下載地址
- 10.3 https://developer.arm.com/downloads/-/gnu-rm
- 11.x 及之后的版本 https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads
環境配置
安裝python3
下載 GCC Arm 工具鏈, 并解壓到合適的目錄
匯出專案, 在專案下創建 virtualenv
$ git clone https://github.com/mbedmicro/DAPLink
$ cd DAPLink
$ pip install virtualenv
$ virtualenv venv
啟用虛擬環境(因為要使用progen)
$ source venv/bin/activate
第一次運行(如果后面倉庫有更新也需要運行)
(venv) $ pip install -r requirements.txt
編譯
方式一
PATH=$PATH:/opt/arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/bin/;python tools/progen_compile.py -t make_gcc_arm --clean -v --parallel stm32f103xb_if
方式二
progen generate -t make_gcc_arm -p stm32f103xb_bl
PATH=$PATH:/opt/arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/bin/;make -C projectfiles/make_gcc_arm/stm32f103xb_bl
遇到的問題
用 gcc arm 10.3 可以順利編譯, 如果用 gcc arm 11.2 會報 SysTick 錯誤, 如果用 11.3 或 12.2 編譯, 會報這樣的錯誤

需要做以下的修改
- 編輯 vi source/daplink/sdk_stub.c
增加以下內容
__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
之后就能順利編譯了
