load kernel linux in board 2c35  

Hello,   i have a problem to load kernal of µclinux in board 2C35, you have any solution to do this,using commande linux of host pc or quartus or nios2eds ?  i followed the step of this link  http://nioswiki.com/operatingsystems...uartusforlinux (http://nioswiki.com/operatingsystems/uclinux/quartusforlinux)  but when i tape jtagconfig the message appeare  [NiosII EDS]$ jtagconfig bash: jtagconfig : commande not found  /opt   if you have any suggestion for this

Hi there, 

thats the same problem as in your other post, your path variable is not correct.  Again for me its: PATH=$PATH:/opt/altera9.1sp2/quartus/bin/

[Altera_Forum]

hello, 

 thank's for you ,  just i'm know in the next step when i would execute this commande:   nios2-download -g /opt/altera9.1sp1/nios2-linux/uClinux-dist/images the follow errors appears  [NiosII EDS]$ nios2-download -g /opt/altera9.1sp1/nios2-linux/uClinux-dist/images/zImage /opt/altera9.1sp1/nios2eds/bin/nios2-download: line 586: nios2-elf-objcopy : commande introuvable /opt/altera9.1sp1/nios2eds/bin/nios2-gdb-server-wrapped: error while loading shared libraries: libjtag_client.so: cannot open shared object file: no such file or directory  please what i should do ?

[Altera_Forum]

you obviously have a big problem with your environment variables. Chech all your Quartus installation, find out where all the Quartus and Nios executables are, and check that your environment variables are correct.

[Altera_Forum]

hello, 

 my variable PATH is     usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/root/bin:/opt/altera9.1sp1/quartus/bin:/opt/altera9.1sp1/quartus/linux:/opt/altera9.1sp1/nios2eds/bin   so do you think in this PATH there is any problem ? or i should add any things ?

[Altera_Forum]

What are the contents of LD_LIBRARY_PATH, QUARTUS_ROOTDIR and SOPC_KIT_NIOS2 ? 

You also seem to be missing the path to the GNU tools (something like /opt/altera9.1sp1/nios2eds/bin/nios2-gnutools/H-i686-pc-linux-gnu/bin)

[Altera_Forum]

hello, 

 thank's for advices  i add the  /opt/altera9.1sp1/nios2eds/bin/nios2-gnutools/H-i686-pc-linux-gnu/bin)to the PATH  when i execute the commande   [NiosII EDS]$ nios2-download -g /opt/altera9.1sp1/nios2-linux/uClinux-dist/images/zImage the message appear:  Using cable "USB-Blaster [USB 7-1.2]", device 1, instance 0x00 Pausing target processor: not responding. Resetting and trying again: FAILED Leaving target processor paused  for the value of variable: QUARTUS_ROOTDIR=/opt/altera9.1sp1/quartus  $SOPC_KIT_NIOS2 =/opt/altera9.1sp1/nios2eds   but there are anthing in variable  LD_LIBRARY_PATH ?

I am getting this same error while trying to download a Linux image, except it seems a little bit intermittent. 

 The download was working, then it wasn't. Then it failed the first time but succeeded on the retry. After that, it worked for a while, but then failed again. For what its worth, the time it failed and succeeded on the retry was using Windows. Most of the time, I have been using Linux.

[Altera_Forum]

The quartus tools and USB drivers seem to work this time, but they can't find the CPU in the FPGA. 

Did you configure the FPGA with the proper .sof image first?

[Altera_Forum]

The .sof file is in the flash. However, even when I try to download it using 'nios2-configure-sof', I still have trouble running with the 'nios2-download'. 

 I was able to briefly regain good performance after running this same sequence on the Windows partition. Eventually, it started failing on the Linux side with this same error.

[Altera_Forum]

Are you sure it is the exact same .sof file in both cases? I fail to see why the CPU wouldn't respond when you try to access it from the linux machine. 

When you run nios2-configure-sof on the silux machine, are you sure everything goes well? No error?

[Altera_Forum]

@Daixiwen, If you were referring to my problem, here is my response. 

 There are no errors when I run nios2-configure-sof. The .sof files in flash and RAM are almost identical. From a software interface standpoint, they would be the same as nothing changed in SOPC builder, just a few GPIO pins were re-routed.  Right now, the problem has not resurfaced, so I'm going to let it go for the moment since I can't gather more relevant data.

hello, 

 for my situation i configure the FPGA with .sof,   there are two .sof one with VHDL other with verilog i use the last with verilog   but do you think this .sof work good,because i try to compile it with quatus give many erros?   error: Tcl Script File NiosII_cycloneII_2c35_full_featured_sopc.qip not found  Info: set_global_assignment -name QIP_FILE NiosII_cycloneII_2c35_full_featured_sopc.qip error: Tcl Script File ddr_sdram_0.qip not found  Info: set_global_assignment -name QIP_FILE ddr_sdram_0.qip

You may have to generate the sopc system first. Open SOPC Builder and click "generate"
