MMU Custom Cyclone II make error

Hi, 

I've got a custom board with a Cyclone II 

 

I used to use an older version of nios2-linux/uClinux but decided it was time to try the MMU version. So, I downloaded the nios2-linux20100621.tar and set to work. 

 

I could not use ./update and get the message below for all --- 

************************ 

[janet@localhost nios2-linux]$ ./update 

update binutils.. 

sopc.et.ntust.edu.tw[0: 140.118.20.145]: errno=Connection timed out 

fatal: unable to connect a socket (Connection timed out) 

************************ 

I also tried to ping 140.118.20.145, it doesn't work. Is this server down? 

 

What could cause that I've tried lately and get that I used to get updates and I haven't done anything to my home network. 

 

But I set to work anyway. I followed the Creating a Nios II Design with an MMUI added my board etc.  

 

But when I do the "make" I get this "vmlinux.lds:380: syntax error 

 

Isn't that a generated file ?? Any help will be greatly appreciated. 

 

Thanks -

This is the newest Linux based release. Structured differently than the previous. There is a god document "Running Linux on the "Altera Nios II Processor USER GUIDE version 1.0" that a work mate gave me (not sure where he found it). 

 

The file is the "nios.h" that you use to reference your "custom_fpga.h" file 

 

It's in the nios2-linux/linux-2.6/arch/nios2/boards/MYboard/include/asm  

 

I'm still trying to get my custom driver compiled into the kernel (porting over from older nios2-linux release) -- can't find "asm/nios2.h" ... but I've been sidetracked on something else. 

 

I hope that clarifies things.

When you are switching to LINUX nios2 and porting your custom drivers over 

 

The include used to be# include <asm/nios2.h> 

 

NOW --- # include <asm/nios.h>  

 

No more "2"

I think the document you are referring to is http://alterawiki.com/uploads/e/e6/opensource_linux_niosii_user_guide_-_fixed_toc.doc

 

Too bad the filename does not match the title....

************************ 

Hi guys, 

 

Do you still have the document " Running Linux on the "Altera Nios II Processor USER GUIDE version 1.0" ? If do, can you please share the link. 

Thank you.
