Altera lab SoC FPGA Linux training

Hello,

I apologize if I’m in the wrong place.

I’ve got a DEO-Nano-SoC from Altera/terasic and try to follow an Altera Tutorial which doesn’t appear to work very well.

It’s the “SoC FPGA Linux Training v15.1 – Lab 1 (Software) Build a preloader, bootloader and kernel”. I don’t have any link, we gave it printed to me.

I manage to complete all up to the “building a device tree” part.

But in the next one “creating a booting SD card image”, the command using make_sdimage.sh give me an error : “could not copy bootloader image to block /dev/loop”

I run the tutorial on a 64 bits 14.04 LTS Ubuntu VM

Can you help me please .
