[BOOT.BIN created with VITIS doesn't work on Genesys ZU 5EV]

I solved this problem for myself by using the bootloader in the Genesus ZU Hello World demo.   There appear to be a customizations for bootloader for the Genesys board that are not found in the stock code.    It is a little bit inconvenient that to update the hardware specification, I have to drop in psu_init.c and psu_init.h files into this special build.   

[BOOT.BIN created with VITIS doesn't work on Genesys ZU 5EV]

 The BOOT.BIN file is produced in Vitis does not work.   When I copy the BOOT.bin file to the SD card, it does not start up and the Error light turns on.      Does it require a separate FSBL application, or does the one produced in the platform suitable?
