[Arria 10SX] Fail to load QSPI flash using quartus_hps

Hi MathiasB,

Can try refer and follow this document of buiding and flashing your Arria10 u-boot QSPI image first:

https://rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10

There are some details on the types of generated files for QSPI booting.

Thanks.

Hi,

Thank you for the link.

However, I am a bit lost here. Since i am using Quartus pro 19.1, there seems to be differences with what is presented in the link.

For instance, when I run make to build u-boot, I do not have any "spl/u-boot-splx4.sfp". Also, I do not have this "board/altera/arria10-socdk/fit_spl_fpga.its" file for mkimage.

I tried again earlier and for some reason I managed to successfully run "quartus_hps -c 1 -o P -a 0x0 uboot-mkpimage.bin" (I did not verify if it *truly* worked, though). I had to try several times the same command before that.

Now I am trying to run "quartus_hps -c 1 -o P -a 0x720000 pl.rbf.img", but it fails just like shown in the image attached to my first message.

Do you think the type of file I am using is the cause?

Since the "percentage of loading" at which quartus_hps is never the same, I would guess it has something to do with an unreliable state of the HPS. Does the HPS have to be in a particular state (if that makes sense) for quartus_hps to run?

Hi MathiasB,

I am not sure how you get/generate your boot image in the first place or documents that you refer to build your project.

Normally I use the gsrd as the base for my project build, so better try to test with a default gsrd version first.

You can try peform the QSPI flashing with quartus_hps cmd using the working gsrd example and see any difference from the outcome.

You can also find some of the prebuild gsrd in the link below:

Hi,

I am refering to this user guide: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug-a10-soc-boot.pdf

which in turn points to this link: https://rocketboards.org/foswiki/view/Documentation/A10GSRD160QspiBoot

The only differences are that I am targetting a bare metal application and using the GUI.

So in the end, I only have the "FPGA Configuration File in RBF format, with the mkimage header" and "U-Boot Binary and Device Tree, wrapped with mkpimage header" files to program in the Flash.

As for the GHRD, I found a couple designs for A10 and Quartus 19.1 with your link, thank you.

However, I could not find documentation on these. Therefore, I am not sure how to program them in my Flash memory and how to rebuild them to target my board (as I do not have a A10 SOC devkit, I fear to damage my board with wrong I/O assignments).

Hi MathiasB,

Are you using a custom board? I think the GSRD design will not spoiled your board.

You can try to program them following the document mentioned from previous comment:

https://rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10

There is a section for Arria 10 where it is using the quartus_hps cmd to flash in different generated output files.

Those files can be obtained from the GSRD link from previous comment:

Thanks.

Hi,

Yes this is a custom board.

The quartus_hps commands in the document are the ones I am using.

It seems a solution to this is to reduce the JTAG clock speed using :

$ jtagconfig --setparam 1 JtagClock 12M

I could then run quartus_hps to program u-boot image in the Flash with no problem several times.

However it considerably slows down the programming.

Regarding jtagconfig command, I saw that setting the JtagClock to 12M actually results to a value of 6M (based on the output of a following "jtagconfig --getparam 1 JtagClock"). If I set the value to 6M, it is effectively set to 6M.

Is that a known problem? Please note that I use USB Blaster II with quartus 18.0.

Hi MathiasB,

Sorry for late reply, I have tested the Jtag clock thing. I think it does not support 12M as It will automatically set to 6M if I perform jtagconfig --setparma 1 JtagClock 12M.

Thanks.
