Loading image to SDRAM under ubuntu

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.

Kindly any help?

Thanks,

Alex.

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

N.

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.

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?

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.

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.

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.

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.

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