用的芯片是hcwb392，CORTEXM4内核，512KB FLASH;188KB RAM。
自己移植的rtthread nano版本，链接文件是直接复制hc32f460的bsp的，gcc编译，编译结果如下：

用了CmBacktrace-v1.4.1,芯片一启动就报如下错误。

hard fault on handler

mem manage fault:

```

去除CmBacktrace后不会上电重启，但是会偶现HardFault错误。
当我屏蔽掉一些程序让编译出来的程序小于使用率的43%后，程序就能正常运行？芯片大flash和ram应该绰绰有余的呀？堆内存也有余，请教各位大佬知道是什么问题或者有什么解决思路？
