Bridge Communication Issues on Agilex SOC Custom Board

Dear Experts,

I am reaching out for support regarding bridge communication issues on our custom board featuring the Agilex SOC (AGFB027R24C2I3E), which uses EMMC as the boot medium.

Despite successfully initializing U-BOOT SPL 2023.07 and ATF v2.9.0, and enabling bridges via the "bridge enable" command, the board frequently stalls at the U-BOOT stage and occasionally undergoes an unexpected reset. Moreover, we are unable to establish communication with the FPGA through the HPS2FPGA and LWHPS2FPGA bridges.

Thanks & Regards

    Hi Raju


    Do you mind sharing us the boot logs that you are experiencing the unexpected reboot?

    Have you enabled the bridges in the quartus design for your board?


    Regards
