how to debug elf

Hello everyone,

I have compiled my application into an ELF file, for example, "myapp_elf", following the instructions in this [issue.](https://github.com/apache/nuttx/issues/2323), After downloading it to the development board, I want to debug this "myapp_elf" file. What configuration options should I add to support debugging ELF files? I have referred to this link for debugging [methods,](https://cwiki.apache.org/confluence/display/NUTTX/Debugging+ELF+Loadable+Modules) but it is not very convenient to use and sometimes results in errors. Are there any other better alternatives?
