Nios II System download problem!

Hello everyone! I'm new to Altera's FPGAs and Nios soft cpu!

I got a DE2 board a few days ago from my university and I'm playing around with it to get to know it better! It has a Cyclon II device on it! I downloaded the following software from Altera's website:

1.quartus ii web edition software v9.1 Service Pack 1

2.[/B][/B]nios ii embedded design suite

3.modelsim altera

I created a system with Nios II, a Jtag Uart interface, two parallel IO interfaces and an on-chip memory. I configured each component, i constrained the clock, I assigned the pins on the board and I compiled it successfully! Then I downloaded it to the board!

Up till now everything seems to work perfectly! The problem arises when I try to compile and download my code for the Nios core to execute! I first used Altera Debug Client to compile and run my code (simple led control with switches) but I got the following message:

Writing "system.h" in "C:\Users\GeorgeK\Documents\QuartusProjects\sopc_builder_tut\app_software\include" directory...

/usr/bin/bash: nios2-elf-ld: command not found
Compilation stopped.

Of course I have already configured system options (ptf file etc) and I tried it with assembly and C! Same problem arises for both!

Next I try to use Nios II EDS Eclipse platform! I create a BSP project using the sopc info file wich was generated by SOPC earlier (in design time) in Quartus! Then I created a Nios Application project linked to the BSP I just created! I add a .c file to the project and I write my code in there! The code is the following:

#define Switches (volatile char *) 0x0003000# define LEDs (char *) 0x0003010
void main()
{
    while (1)
    {
        *LEDs = *Switches;
    }
}

When I try to build the project I get an error that says something that the memory (the on chip memory I used) has to be larger! And it exits saying this:

What can I do?!?!?!?!?!:confused: Is Eclipse IDE generating larger code than the Debug Client? The Debug Client seems a lot easier to use and is straightforward for tutorials and stuff! How can I get it to work!!?!

ps: I also get this at the Eclipse platform error and stuff:

../Lights_bsp//libhal_bsp.a(alt_close.o)(.text+0x128): In function `alt_get_errno':
HAL/inc/sys/alt_errno.h:81: Unable to reach errno (at 0x00004024) from the global pointer (at 0x00010880) because the offset (-51292) is out of the allowed range, -32678 to 32767.

I even made the on chip memory larger but nothing changed!

Thank you all in advance for any help you may provide!

Cheers,

GeorgeK
