Agilex5 .sof programming error

Has anybody ever seen this error when trying to program a design with a .sof:

Resetting CPU ...

### ERROR ### Please RESET the board ###

I am using this build flow for the OS, and the GHRD from CDROM v1.4.0

It is worth noting that when programming with the .jic generated by the same project using:

quartus_pfg -c golden_top_hps.sof golden_top_hps.jic -o device=MT25QU512 -o flash_loader=A5ED065BB32AR0 -o mode=ASX4

There is no such issue.

Thanks

    Hi K606,

    Sorry for the delay in responding to this thread. Based on the error and your explanation on jic file is working, with the assumption of the same sof file is used for the jic generation as well (not due to mismatch handoff settings), the only difference that I could think of is that the with the sof file, the configuration is volatile/not persistent in FPGA SRAM and lost after every reset or power cycle, thus error will occur when reboot/power cycle and FPGA configuration is not there.

    Along these lines

    Loading Environment from FAT... Unable to read "uboot.env" from mmc0:1... Loading Environment from UBI... "Synchronous Abort" handler, esr 0x96000010, far 0x108d2000

    1st warning usually non fatal, just indicating cannot load or no sd card

    2nd warning is indicating loading environment from NAND/UBI filesystem but fails together with the synchronous abort indicating ARM CPU tries to access the address that is not valid , most likely on the FPGA register side bridges or peripherals

    As for JIC , it is stored in persistent memory and loaded automatically every reset/reboot thus HPS is able to boot successfully

    Thanks

    Regards

    Kian
