I'm running a microblaze MCS on a Spartan-6 connected to XSDK via a Digilent USB Cable, all populated on a Digilent Cmod S6. For debugging GDB+XMD is used as TCF System Debugger won't work (Message: Download error; Context not found for: ...). XDSK is latest official Spartan-6 supporting Version 14.7 and running on a Windows 7 PC.
After increasing timeouts for GDB (remotetimeout set to 300), XMD Stratup Launch timeout (set to 200000) and XMD Startup Transaction timeout (set to 240000) debbuging is very slow, but possible for very small programms. If the programm size reaches up to about 6500 Byte I'm getting always an XSDK timeout error "Target request failed: Target is not responding (timed out)".
Is there any timeout left I haven't already increased? Any other suggestions to get debugging running again - either with GDB or with TCF?
I've also tried to us the latest XSDK-Version running under Linux OS, but there XSDK complians it is unable to find "mb-ar"...
