assembly - 为 ARM 发布交叉编译 FreeRTOS 程序
问题描述
我想为我的目标构建 FreeRTOS 可执行文件，该目标是具有 AM335X ARM Cortex-A8 处理器的 beaglebone black。我正在运行 Windows，但我使用的是运行 linux debian 10 的虚拟机，这是我交叉编译的。uname -a提供：
Linux debian 4.19.0-13-amd64 #1 SMP Debian 4.19.160-2 (2020-11-28) x86_64 GNU/Linux
我是 FreeRTOS 的新手，所以如果我以错误的方式处理这个问题，请告诉我。我的计划是用 C 编写一个 FreeRtos 程序并交叉编译它，然后简单地将可执行文件发送到 beaglebone 并运行可执行文件。我成功地尝试了一个 Hello world 程序，所以我认为它应该可以使用 FreeRTOS 程序。我想让它在两个不同的编译器上工作，因为我想测试两者。第一个是 arm-linux-gnueabihf-gcc，第二个是裸机版本，称为 gcc-arm-8.2-2019.01-x86_64-arm-eabi。我的项目可以在这里找到：https ://github.com/frank2597/FreeRTOS_BBB.git作为快捷方式，我的编译器选项设置可以在这两个文件中找到：
https://github.com/frank2597/FreeRTOS_BBB/blob/master/source/CMakeLists.txt
https://github.com/frank2597/FreeRTOS_BBB/blob/master/source/toolchain.cmake
我正在使用 Cmake 生成 makefile。两个交叉编译器都无法使用我的 testing.c freertos 程序进行编译。当我使用 arm-linux-gnueabihf-gcc 编译器时，我收到各种警告和一些未定义的引用，但编译器达到 100%，make命令的错误如下所示（由于字符限制，无法发布详细输出）：

我正在努力弄清楚这两个编译器有什么问题，我不确定我是否缺少编译器标志，缺少一些源文件，或者可能只是使用了错误的编译器。理想情况下，我希望两者都工作，但感谢您对任一问题的帮助。我还应该说我的项目基于这个似乎实现了一种稍微不同的方法，尽管它对我不起作用：https ://github.com/kryochronic/AM335X-FreeRTOS-lwip.git 如果让我知道你需要任何额外的信息。谢谢您的帮助。
额外信息：我在我的 github 项目中添加了详细的输出。对于 arm-linux-gnueabihf-gcc：https ://raw.githubusercontent.com/frank2597/FreeRTOS_BBB/master/make-output-arm-linux-gnueabihf.md
对于裸机版本 gcc-arm-8.2-2019.01-x86_64-arm-eabi：https ://raw.githubusercontent.com/frank2597/FreeRTOS_BBB/master/make-output-arm-eabi-gcc.md
