pdbg sreset command fail

[liyi-ibm]

Latest pdbg (commit 92006e5) failed on sreset command. But earlier version (commit cb2595c) works.

root@rom277:~# pdbg --version
pdbg 1.0 (commit 92006e5)
root@rom277:~# pdbg -a sreset
No valid targets found or specified. Try adding -p/-c/-t options to specify a target.
Alternatively run 'pdbg -a probe' to get a list of all valid targets

Earlier version works:

root@rom277:~# pdbg --version
pdbg 1.0 (commit cb2595c)
