Everything you need to know is in that referenced wiki page:
https://cwiki.apache.org/confluence/display/NUTTX/Debugging+ELF+Loadable+Modules
I don't know anything about QEMU or RISC-V. But assuming that NSH is
your init application...

Not sure if we need some sort of debug agent in KERNEL build so that it can hel
Yes! For kernel mode each program has its own main() implementation, not
the definition.

It isn't possible to have a unique main() symbol, otherwise we will have a
duplicated symbol, also even if the compiler accepted that, how could NuttX

This is old and does not specifically address kernel mode, but I think most of
the debug tips do apply in kernel mode too. The load address is a constant for
kernel ELF modules so at least that part doesn't apply. But the rest probably
does.

Hi Yf Liu,
I don't know if this minidump server works on 64-bit and with QEMU, but
about the other question how to setup breakpoint in the NSH user space
program, just set the break point to the nsh_main if you want to debug the
NSH itself or set it to program_main to put the breakpoint to some use
