Arria 10: Booting U-Boot from SD-Card does not configure FPGA

Hello, I have adapted the example for the Arria 10 SOCDK (Arria 10 SoC - Boot from SD Card) to the HAN-Pilot-Platform evaluation board from Terasic. I used the make_sdimage_p3.py script to generat...

    Hi @aikeu,

    okay, now im sure: The Intel In-System Sources and Probes IP hinders the FPGA from starting normally after it has been correctly configured by SD-Card. Even the old Quartus-Project works without the ISSP-IP. Now it makes sense why the FPGA starts when a connection to the programmer is established via JTAG or similar.

    My workaround will be, that i only use FPGA Firmware without the debugging features (ISSP, SignalTap, ...) on the SD-Card and when i need this debugging features i will start the HPS with the ARMD DS debugger.

    Thanks for the help, my problem has been solved.

    Regards,

    LFrin

Hi @aikeu,

thank you for your efforts so far.

I tried to edit the prebuilt sd card as you wrote, unfortunately it did not help.

But I think I have found the error. I set up a completely new Quartus-Project with only:

1. Initialized the HPS-Component

2. Debounced the RESET-Button

3. Added a Heart-Beat-LED controlled by the FPGA

After compiling, I first created my SD-Card exactly as in the instructions (Arria 10 SoC - Boot from SD Card) without building a dedicated U-Boot-Target for the Han-Pilot-Platform. The FPGA was configured normally on boot and the LED started flashing (FPGA starts running).

Then i build my own dedicated U-Boot-Target for this board and the FPGA also is configured normally on boot and the LED started flashing (FPGA starts running).

I can exclude that the problem is related to the SD-Card and U-Boot/SPL, both seem to work fine. I think the problem is in my Quartus-Project or the Programming-File. I will now rebuild (component-by-component) my old Quartus-Project until my FPGA no longer starts runinng after booting the SD-Card. So I intend to find the problem.
