Function stack tracing and broadcom6838 functions are implemented in the broadcom6838 development environment.
In the development of embedded devices, the kernel provides good support for function stack tracing of kernel modules, but function stack tracing at the user layer does not provide good support. Collecting and learning function stack traces on the Internet mostly describe the implementation mechanism of the INTER architecture supporting stack frames, or directly provide glibc ready-made
