 >-   When compiling user programs and required libraries, add the option  **-funwind-tables -rdynamic -g**  for stack backtracking.
 >-   The  **-mfloat-abi=softfp**,  **-mcpu=cortex-a7**, and  **-mfpu=neon-vfpv4**  options specify the floating-point calculation optimization, chip architecture, and FPU, which must be the same as the compilation options used by the libc library. Otherwise, the libc library file cannot be found during the link time.
