MMU Custom Cyclone II make error

[Altera_Forum]

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 -  ************* END OF make messages   CC init/version.o  LD init/built-in.o  LD .tmp_vmlinux1 /home/janet/nios2-linux/toolchain-mmu/x86-linux2/bin/nios2-linux-gnu-ld:arch/nios2/kernel/vmlinux.lds:380: ignoring invalid character `#' in expression /home/janet/nios2-linux/toolchain-mmu/x86-linux2/bin/nios2-linux-gnu-ld:arch/nios2/kernel/vmlinux.lds:380: syntax error make[2]: *** [.tmp_vmlinux1] Error 1 make[1]: *** [sub-make] Error 2 make[1]: Leaving directory `/home/janet/NEWEST-nios2-linux/nios2-linux/linux-2.6' make: *** [linux] Error 1 *********************************************

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....

[Altera_Forum]

Yes, that's the document !! 

 It was very helpful.

I got an e-mail saying  

************************ 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.  Moganesh ********************* I don't see that on this message but the link is still good   http://alterawiki.com/uploads/e/e6/o..._fixed_toc.doc (http://alterawiki.com/uploads/e/e6/opensource_linux_niosii_user_guide_-_fixed_toc.doc) ?

I post it but looking back the link is still on the thread and available. The method is not same with latest nios2-linux. Thanks though.
