How can I build the Angstrom Linux kernel and root file system for a CycloneV SoC device?

Hello! I'm a newbie of SoC System. I'm searching how to make complete chain from Quartus-QSYS project up to create image for SD card. I have a De0NanoSOc ATLAS (but goal is to make something running on our PCB with CycloneV, designed on the same base.

I enconutered great problems due to confusion, bad links and bunch of info about Angstrom distro.

1) I attempt to follow rocketboard guidelines for Atlas Deo, but there isn't nothing on the rockboard site, too obsolete

So, I attempt to follow Soc CyclonV altera guidelines, but when it clone the "schnitzeltony" angstrom from GIT it fails, I try to replace link with "pabigot" one, that is present, but there are many errors that are not easy understand for me

2)Only updated angstrom running links I found on Arria10 SoC. On Rocketboard istructions, there is a note that Arria10 can be replaced by Cyclon5 on this distro. Ok , all runs but when I launch last command to do the final image, I receive a fatal error "NO VALID MACHINE CyCLONE5) !!!!!!!!!!!

3) I found a third way: Angstrom 2013.12 from GITHUB (robertofm),

But first error occours: there is only angstrom 2012.12 version. I try to change something to goes, but too many errors occours again.

Well, I READ THAT INTEL (ALTERA) SAYS angstrom is officially supported and checked... where I can download a valid angstrom chain to obtain booting SD image??? TODAY I DONT' FIND A GOOD WAY!!!!

(I use quartus 18.1 std: I ported DeoNanoSoc under Q18 and I compiled succesfully. Then I obtained Preloader and Uboot. BUt when I search for angstrom distro, disaster occours. I have a Oracle VM with Ubuntu 14.06 to do linux operations)

PLEASE HELP US!!!!

I'M ATTEMPTING ANY THING
