Cyclone V SoC / Boot from QSPI issue with Quartus 15.0 and Angstrom distribution

Hi, 

 

I'm trying to boot Linux (Angstrom distribution) from QSPI flash with the following files generated with Quartus 15.0: preloader, uboot, rbf file, dtb file. 

 

With Quartus 13.1, I can boot Linux (Poky distribution) from QSPI flash. This works on the Arrow SoCkit board and a custom board too.  

To boot from QSPI with Quartus 13.1, I followed the instruction on rocketboards website (https://rocketboards.org/foswiki/view/documentation/gsrd131qspiboot) (how generate the files, where store the files in QSPI, how edit preloader and uboot to boot from QSPI, How compile a minimalist rootfs, ...). 

 

I want to upgrade Quartus version from 13.1 to 15.0, because some bugs were fixed regarding preloader and uboot issues (HPS register configuration bugs if LOAN I/Os are used). But I read, if I'm using Quartus 15.0, I need to use Angstrom distribution.  

I cannot boot from QSPI with Quartus 15.0 and Angstrom Distribution. No documentation is available on the rocketboards website (only available for Quartus 13.1). 

 

Do you know where I can find a tutorial how to boot from QSPI with Quartus 15.0? 

 

If I use preloader and uboot files compiled on Quartus 15.0 and rbf /dtb files on Quartus 13.0, I can boot Poky distri. from QSPI. The LOAN I/O bugs are solved... 

 

Quartus is installed on Windows 10 x64 and the compilations of zImage and rootfs are performed on Ubuntu 12.04 x64. 

 

Thanks for your help 

 

Regards, 

Julien

Did you ever resolve this? If so could you help me out. I tried Q14.1 about 6 months ago and now am trying Q16.1 --- No luck it doesn't like the .dtb file (but the same .dtb file boots from the SD Card). 

PLEASE LET ME KNOW!!! THANKS!

UPDATE - I'm using Quartus 17.0. I started with the Macnica SODIA GHRD 16.1 design, ran QSYS, re-compiled and createing the preloader, u-boot, .dtb, .rbf on a Ubuntu machine. I created the zImage from the "kernel.config" in the "intelFPGA.17.0/embedded/embeddedsw ..." prebuild images directory. 

 

I programmed a SODIA board QSPI via the HPS programmer (our custom board WILL not have an sd card). 

 

It boots from QSPI

Hi, 

 

There is not Cyclone V reference for boot from qspi in newer version(Angstom), as the last version for cyclone V soc was with poky release.

CloseCL, 

I get that.  

 

What I was letting people know is that I WAS SUCCESSFUL even without "Cyclone V reference for boot from QSPI" for the Angstrom release. And I can share the steps if need be. Too busy to do a full write up right now. 

 

All the reference designs (which is our firmware starting point for custom projects - then we add our custom IPs) use Angstrom and there was another post where someone never got their system embedded to the QSPI after 14.1 (or they never reposted).
