大家好,
我正在将一个 C++ 项目从
STM32H7 EVAL 板移植到 STM32H7 Nucleo 144。
该项目使用CubeMX 生成项目,然后我移植所有源代码并设置c/c++/linker 目录、符号和设置。
该项目使用 FreeRTOS,当在库实例上调用 new() 时,RTOS 的一个线程将在默认错误处理程序 (_exit()) 中进入无限循环。其他线程继续运行正常。
链接器将用户数据放在 RAMD1 中,因为它是最大的部分,我需要空间。
我检查/尝试过的一些事情:
- 库使用与项目相同的 C++ 版本 (C++ 14) 编译
- 启用硬件 FPU(库使用浮点数)
- 链接器脚本中的最小堆栈和堆就足够了
- RTOS 线程分配的堆栈/堆大小足够
- RMD1 部分启用时钟
- 尝试在链接器中将数据对齐到 4 字节和 8 字节
- 128 / 4096 字节 malloc() 页面大小
逐步执行说明,我可以看到这是导致问题的行。
这是我的链接器脚本,以防有任何帮助

该库被认为是好的,并且已经在不同硬件上的同一个 IC 上运行。
非常感谢任何帮助!
