I was trying to setup to do USB Boot Mode using `dfu-util`. I was referencing the instructions given in:
I tried to refer to the ZCU104 Evaluation Board User Guide here:
But this makes no mention of the USB boot mode. Table 2-4 on page 16 lists only SD Card, JTAG, and SPI boot modes, but not USB boot mode.
I was able to build an FSBL image into a BOOT.bin (after modifying it as directed in the tutorial). I booted the board with the SW6 switches set for USB mode. Using dfu-util, I could see the Target system:
Then I loaded the BOOT.bin I had created. This seemed to load successfully:
On UART1, I saw:
However, when I tried to follow-up and load usb_boot.bin, it seems the Target system is not in the correct mode to accept the connection:
I'm not sure, but I'm guessing that the FSBL I built somehow isn't entering the correct mode for further stages of USB booting? Perhaps the indicated modifications in the document aren't correct in my particular case? Can you please advise, or direct me to someone that can help us on this issue? Thanks!

Maybe enable the detailed debug prints in the FSBL so it prints more than just the banner to see if it enters the porper mode.
I can take a look at the .bif if you want (just to double check).
