Starting debug server

Hello,

I was using DS5 fine for connecting to my Altera board and then today it just stopped working, even the examples do not work. So when trying to load the baremetal example, I get this error:

Starting debug server
Waiting for debug server to start accepting connections
processrunner.py:8: RuntimeWarning: Unable to determine _shell_command for underlying os: nt
import subprocess
RDDI-DAP-DS : ERROR failed to connect to RDDI DAP target
RDDI Error Code 4107 : Connection to target failed.
RDDI DLL = rddi-dap_altera_2.dll
RDDI CFG = C:\Users\mgriffit\AppData\Local\Temp\ds5_8070900945896429705.txt

exited with error code: 1

Any ideas what to try? What could have happened?

Hi,

Could you tell me what version and build of DS-5 you're running and and on what OS? It looks like something is going wrong in the code that builds up the command to launch the debug server.

Regards,
Mike

Hello,

I am using Windows 7 and Redhat, on both OSs it did not work. However I randomly changed the dip switches and then it started working again. Orginally, I had them as stated in the Altera Cyclone manual. Now I am not 100% sure why it works or which configuration I have Any extra knowledge would be welcome.

Thanks,

Hi, well I was thinking something was wrong with the runner scripts that may be OS or OS+environment dependent. However, your response leads me to conjecture that the switch settings on the board may have changed the configuration so that debug wasn't possible by the route you are choosing. The switches and DIPs on the Cyclone board I have can be used to enable JTAG or USBBlaster debug of the ARM cores in the system. The error message doesn't help us identify that though.

Regards,
Mike.
