Re: SIOCSIFADDR error

Altera_Forum · ‎08-24-2005

This is a custom board. I have taken everything out except for the Flash and SDRAM. It is actually a fairly simple system, flash, sdram, and an ethernet port. I don't use tightly_coupled_memory (have not familiarized myself with it yet), and my data cache line size is 4 Bytes, exception pointer is set to SDRAM.

I am out of ideas. I also can not load the kernel into RAM from the IDE, I'm forced to burn the Flash each time I make a change. I get the following message from the IDE console. Do I have a JTAG problem? I'm using a USB Blaster "Rev B".

Doug,

Did you ever figure out your problem?

I am also developing a custom board. I also get the mysterious error:

assertion "m_state == STATE_DEBUG" failed file "nios2debug.cpp", line 1695 signal 6

What does this message mean? I just opened an SR with Altera, but have been stuck with this for a couple of weeks now....

My conditions are as follows:

I get this error just by reversing the order of how I open my tools. If I open a shell to load my hardware before opening IDE I get the error.

If I open IDE before opening my SDK shell I DO NOT get error. The result is reproducible with some of my boards. Other boards will hang with the message:

nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

or not respond to further commands.

I am in a jam because my boards have been manufactured and assembled and are ready for production , and now this error shows up.

Baycool,

Nope, I never did figure it out. I do know that I can connect to my board through the ethernet port with out any problems. Everything works fine here, I can telnet in, ping it, and the web server runs just fine. I'm pretty sure this is a JTAG UART issue. I just don't know what yet.

I'm working on trying to figure this out. We got another custom board back late Friday. I will get that one up and running to see if the same problems arise.

I tried your trick of opening the IDE first. It still bombed on me.

I'll let you know if I find anything out.

Thanks Doug for your reply.

It is very consoling to see that I am not the only person suffering with these problems.

Last week I was so elated even to find a hit on my search for "m_state == STATE_DEBUG".

I get so many communications problems with the JTAG UART that this is an almost impossible problem to debug.

I tried a "grep" on the message in the entire /kits directory and could turn up NOTHING.

At the very least I would like to see this message in C source and atleast know for sure the cause of the problem.

By the way, do you even have an occasional comm problem with your ethernet port?

Baycool,

At this point, I can't isolate the problem, therefore, I can't say it is a JTAG UART problem, but I'm pretty sure that is the source of my headaches.

Up to now, I have not had any problems with my ethernet port.
