Loading image to SDRAM under ubuntu

[Altera_Forum]

Hi, 

  I am trying to run uclinux on DE0-Nano, and i successfully generated the zImage, but iam unable to load the image into SDRAM, it showing error like  alex@alex:~$ nios2-download -g ~/uClinux/distro/nios2-linux/uClinux-dist/images/zImage  /opt/nios2eds/bin/nios2-gdb-server-wrapped: error while loading shared libraries: libjtag_client.so: cannot open shared object file: no such file or directory.    Where is the mistake? Thanks in advance.

My guess is that you need to add the quartus library directory containing the required so files to the LD_LIBRARY_PATH variable. 

 For Quartus v12.0 it should be located in <path-to-quartus>/12.0/quartus/linux64 where <path-to-quartus> depends on where you installed the software.  Try this:  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<path-to-quartus>/12.0/quartus/linux64; nios2-download -g ~/uClinux/distro/nios2-linux/uClinux-dist/images/zImage  N.

Thanks for ur reply sir,but i executed the nios2-download command its showing like this 

  alex@alex:~$ nios2-download -g ~/uClinux/distro/nios2-linux/uClinux-dist/images/zImage there is a problem with the quartus ii installation on your computer. please use `jtagconfig` for further diagnosis.    Kindly any help?  Thanks, Alex.

[Altera_Forum]

Can you try executing that command as root? Just to check if it's a permission issue. 

 N.

[Altera_Forum]

Thanks you sir, tried as root but....... 

  alex@alex:~$ sudo nios2-download -g ~/uClinux/distro/nios2-linux/uClinux-dist/images/zImage [sudo] password for alex: ***** sudo: nios2-download: command not found  alex@alex:~$ gksudo nios2-download -g ~/uClinux/distro/nios2-linux/uClinux-dist/images/zImage here it doesnt show any error but no output,just it return to command prompt  alex@alex:~$ gksudo ./nios2-download -g ~/uClinux/distro/nios2-linux/uClinux-dist/images/zImage here also it doesnt show any error but no output,just it return to command prompt   Else i have to check like this or any other method?  Where is the mistake? Thanks, Alex.

[Altera_Forum]

Sir, 

   For suppose if i got error like this (As mentioned below)  there is a problem with the quartus ii installation on your computer. please use `jtagconfig` for further diagnosis  I came to know, i have to kill jtagd as mentioned below  $ sudo killall jtagd $ sudo /opt/quartus/bin/jtagconfig -n   Is it true? what i have to do? Kindly any help?

[Altera_Forum]

Try the following command to see if it resolves the jtag issue for normal users: 

 echo 'ATTR{idVendor}=="09fb", ATTR{idProduct}=="6001", MODE="666"' | sudo tee -a /lib/udev/rules.d/51-usbblaster.rules  Reboot your machine just to make sure it takes effect.  N.

[Altera_Forum]

Thanks for giving replies 

 still iam strucking there only  Sir, once i close and again i open my terminal,   if i type donload command  1.alex@alex:~$ nios2-download -g ~/uClinux/distro/nios2-linux/uClinux-dist/images/zImage  /opt/nios2eds/bin/nios2-gdb-server-wrapped: error while loading shared libraries: libjtag_client.so: cannot open shared object file: no such file or directory   then i typed   2.alex@alex:~$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/quartus/linux and press enter alex@alex:~$   3.alex@alex:~$ nios2-download -g ~/uClinux/distro/nios2-linux/uClinux-dist/images/zImage there is a problem with the quartus ii installation on your computer. please use `jtagconfig` for further diagnosis. i added the your line as u mentioned in the previous post And finally in my 51-usbblaster rules file is like this  #usb-blaster bus=="usb", sysfs{idvendor}=="09fb", sysfs{idproduct}=="6001", mode="0666" bus=="usb", sysfs{idvendor}=="09fb", sysfs{idproduct}=="6002", mode="0666" bus=="usb", sysfs{idvendor}=="09fb", sysfs{idproduct}=="6003", mode="0666" echo 'attr{idvendor}=="09fb", attr{idproduct}=="6001", mode="666"'  Y , once i close my terminal ,again i will open na no library path. I have to fix this problem, kindly any help? Where is the mistake? Thanks, Alex.

[Altera_Forum]

The last command I gave you was supposed to be executed only once. 

In the archive attached to this post are two files:  altera.conf -> put this one in /etc/ld.so.conf.d (this way you don't have to export the library path every time) 51-usbblaster.rules -> put this one in /lib/udev/rules.d  Reboot your machine and try again.  N.

[Altera_Forum]

Sir, 

 My usb blaster rules it is in /etc/udev/rules.d/51-usbblaster.rules,can i delete this one, imean as showed in my previous post  According to you , i have to place /lib/udev/rules.d, in my path(/etc/udev/rules.d/51--usbblaster.rules) this file can i delete or what?   Thanks, Alex.

[Altera_Forum]

Yes, you can overwrite the /lib/udev/rules.d/51-usbblaster.rules you created previously with the 51-usbblaster.rules in the zip file. 

 N.

[Altera_Forum]

Also remember to put the quartus bin directory in your .bashrc file 

 alex@alex:~$ gedit ~/.bashrc &  and add the following line to the bottom of the file  export PATH=$PATH:/opt/quartus/bin  Then log out and log back in.  N.

[Altera_Forum]

I tried all the steps , as u mentioned in your previous post, but same problem, where is the mistake? 

 error  there is a problem with the quartus ii installation on your computer. please use `jtagconfig` for further diagnosis.  else cont we download the image into SDRAM under ubuntu? Thanks, Alex.

Are you running an old version of quartus? Perhaps you're better of reinstalling v12.0 of Quartus II? 

 N.

[Altera_Forum]

Iam using quartus 11.1 service pack, is it ok?, otherwise i have to reinstall quartus with 12v? and one more thing i have downloaded nios2-linux-20090929.tar under windows, is any problem ? 

    Thanks, Alex.

[Altera_Forum]

Please do the following: 

 1. Open up a terminal and type "jtagconfig" followed by enter. What does it say?  2. Install libstdc++6 using the command "sudo apt-get install libstdc++6"  N.

[Altera_Forum]

alex@alex:~$ jtagconfig 

1) USB-Blaster variant [7-1]  Unable to lock chain (Insufficient port permissions)  and i installed the libstdc++6 also, and i am using ubuntu12.04     Thanks, alex.

[Altera_Forum]

That's exactly the kind of problem the /lib/udev/rules.d/51-usbblaster.rules file is supposed to fix. 

 Connect your altera device to the usb port and execute "lsusb" in a terminal. The output should contain a line like this: Bus 003 Device 002: ID 09fb:6001 Altera Blaster  N.

[Altera_Forum]

Ya, the output is like . 

 alex@alex:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 1210:25f4 DigiTech  Bus 006 Device 002: ID 15d9:0a4c Trust International B.V. USB+PS/2 Optical Mouse Bus 007 Device 004: ID 09fb:6001 Altera Blaster   then how to fix the problem?

[Altera_Forum]

Are you sure you installed the rules file correctly? 

 Type in "cat /lib/udev/rules.d/51-usbblaster.rules" at the command prompt. It should say: ATTR{idVendor}=="09fb", ATTR{idProduct}=="6001", MODE="666"  You did reboot your machine, right?  N.
