I have followed the steps mentioned in Cross compiling for BMC (ARM) of the README for Building on a x86 server and then did rsync of the binary to the Witherspoon BMC.

Then executed the ./pdbg -a probe command in the Witherspoon BMC shell.

root@witherspoon:~# pwd
/home/root
root@witherspoon:~# ls
pdbg
root@witherspoon:~# ls -l
total 396
