need help for niosII 9.1 flash programmer

Hi,

I'm in the process of migrating a SOPC design to QSYS (using Quartus II version 11.1sp1). Doing so, I was checking that things are working as they should. When using the Flash Programmer inorder to program the flash memory device, I was getting the Error code 4 message when using the Flash Programmer:

Using cable"USB-Blaster[USB-0]",device 1,instance 0x00

Resetting and pausing target processor:FAILED

Leaving target processor paused

"Error code:4 for command:..."

It turned of that in my case "faulty" connections in QSYS was causing the error message. I had connected the NiosII Processor's "jtag_debug_module_reset" to several reset ports for IP's in the QSYS design, (including the Generice tri-state controller/conduit pin sharer/conduit bridge IP modules).

Removing these connections made the error message go away. Perhaps this can be of help to others getting the same error code
