Question

Hi I have installed ubuntu in virtual box and I downloaded petalinux2017.1 into downloads directory and moved the run file into a directory called PetaLinux in opt in my root directory.

But i couldnot run the file when my commands are in the following way and it is showing an error "command not found".

my@my-Ubuntu: /opt/PetaLinux$petalinux-v2017.1-finalinstaller.run

i tried the same with sudo and the error is same and i want to install it into the directory PetaLinux and I am a beginner in these.

Answer 1

Try these commands :

cd /opt/PetaLinux
sudo chmod 777 PetaLinux$petalinux-v2017.1-finalinstaller.run
./Petalinux-v2017.1-finalinstaller.run

Answer 2

Why you put this into /opt/?

Whatever, try this:

$ cd /opt/PetaLinux
$ sudo chmod +x petalinux-v2017.1-finalinstaller.run
$ ./petalinux-v2017.1-finalinstaller.run
