Arria 10 Preloader SPL Uboot Error

Hi, I am getting an error loading/debugging uboot through the Arm Development Studio debugger on my custom Arria 10 Han Pilot board that boots from QSPI Flash. I am following the instructions here ...

Hi R_G,


The address 0x01000040 is referring to the DDR address.

The Han Pilot board which you are using, does it has any failure with DDR in the logs during the initial state of booting which is the FSBL, First stage bootloader which is one of the file u-boot-splx4.sfp required in the boot up process.

Expected to have logs like below:


U-Boot SPL 2022.04-21237-gfda0d9176f-dirty (Nov 30 2022 - 22:13:33 -0600)

DDRCAL: Success

DDRCAL: Scrubbing ECC RAM (1024 MiB).

DDRCAL: SDRAM-ECC initialized success with 148 ms


Another thing is without relating to Arm DS debugging, will the system boot up like normal solely by flashing the required files to reach Uboot user space in the boot up operation?


Thanks.

Regards,

Aik Eu

    Hi Aik,

    I don't get a U-Boot SPL log at all during a normal boot from the SD card (not using the debugger). I don't find the expected u-boot-splx4.sfp file on the SD card image either. How can the DDR RAM get configured without it? I have included the U-Boot log that you requested for your reference. It shows that Linux boots up to the command line prompt.

    Thanks,

    Richard
