Ubuntu 22.04 GCC Arm 12.2.rel1编译 DAPLink

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

• 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

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_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

1. 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;
}

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
