RUN AS HARDWARE error

[Altera_Forum]

hello any one !! 

In my custom board,FPGA works well when I download *.pof by AS mode or *.sof by JTAG mode, but I get the error information as following when I "RUN AS HARDWARE" in NIOSII IDE.  Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00 Processor is already paused Reading System ID at address 0x02000908: verified  Downloading 01000020 ( 0%) Downloading 01010000 (98%)assertion "m_state == STATE_DEBUG" failed: file "nios2 debug.cpp", line 1695 Signal 6  any one give me some advices? thanks in advance

Jesse, thanks a lot for your advices!  

I am a new man for NIOSII, and how can I try it with "on_chip ram"? set it in SOPC builder?   Another, Something new take place in my work today? When I "run as hardware" , sometimes I can downloading, sometimes I get the above error information and sometimes I get the errors information as following:  Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00 Processor is already paused Reading System ID at address 0x02000908: verified  Downloading 01000020 ( 0%) Downloading 01010000 (96%) Downloaded 67KB in 1.9s (35.2KB/s)  Verifying 01000020 ( 0%) Verify failed  Leaving target processor paused  and the most case is the last one!! I check the PCB routing and it is ok but I can not sure if SDRAM is ok now.  I had asked for the answer from other forum; some people had the same error information as I have, but I can not get the answer from them.

I'm getting similar errors. I am using an Altera Eval kit, which works with many of the examples that came with it, no hardware problems at all.  

 If I build a "Hello World" app using one of the altera Nios II projects that came with it, then it works fine.   I am trying to build my own Nios II core test system (to use on my design when it is assembled) and I get the "m_state == STATE_DEBUG" error messages.
