Loading image to SDRAM under ubuntu

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

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.

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

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?

Kindly any help?

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.

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.

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

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.

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

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"

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

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?
