RMT ERROR : failed to get remote thread list

[Peter Skvarka]

I use arm-elf-insight version 6.6 and after success connect into OpenOCD
with JTAG,
I am trying to issue in gdb console:
"info threads"
after it there is displayed two dialog boxes:
"RMT ERROR : failed to get remote thread list"
and
"couldn't restore frame in current thread, at frame 0"

What does it mean this error ? How can I correct it ?

Thanks,
Peter
