FSBL fails at "Xilinx Zynq MP Firs?" - bringing up custom UltraScale+ design

[dtubbs]

Greetings!

I'm brining up a new custom UltraScale+ design, and when the board boots, all I get is the text "Xilinx Zynq MP Firs" followed by one bad ASCII character. You can see from the attached image.

This is repeatable, in that each time I power-on the card I get exactly these characters and nothing more.  Any help would be appreciated!

Are you sure that the bitstream used matches the target device. I do see this if I accidently boot a zcu111 image on a zcu102 for example.

How was the boot image created? in SDK, or Petalinux?

Can you share the BIF file used?

Thanks for following up!

Right now, I'm jus trying to bring up the PS side, so I did not include a bitstream when I created BOOT.BIN.  After doing a petalinux-build, I followup with:

petalinux-package --boot --format BIN --fsbl ../path-to/zynqmp_fsbl.elf --project ../path-to-project --uboot ../path-to/u-boot.elf -o BOOT.BIN

The BIF file is found in my <plnx-project>/build/bootgen.bif:

the_ROM_image:
{
        [bootloader, destination_cpu=a53-0] /tmp/tmp.aLFcSTahYp/zynqmp_fsbl.elf
        [pmufw_image] /tmp/tmp.aLFcSTahYp/pmufw.elf
        [destination_cpu=a53-0, exception_level=el-3, trustzone] /tmp/tmp.aLFcSTahYp/bl31.elf
        [destination_cpu=a53-0, exception_level=el-2] /tmp/tmp.aLFcSTahYp/u-boot.elf
}

Hi @dtubbs 

Did you start testing your board using Xilinx SDK? Example tests:

1. Load helloworld application
2. Load FSBL in JTAG boot mode

It's always good to ensure your FSBL has the right configuration of the hardware prior starting to boot a complete image with U-Boot.
