I tried to reproduce the problem on Genesys ZU-5EV, using the Hello World demo, which we recently migrated to Vivado 2023.1. I tried to program the QSPI flash from Vitis multiple times, starting from offset 0, and it completed without error every time.
For reference, I used this repo: https://github.com/Digilent/Genesys-ZU, which I cloned and then checked out the 5EV/HELLO-WORLD/2023.1 tag.
To rebuild the project, I followed the instructions from this page: https://digilent.com/reference/programmable-logic/genesys-zu/demos/hello-world.
NOTE: In the respective page, the instructions marked with orange ("After recreating a Vitis workspace from source...") under the "Using the Latest Release" tab were very important in correctly compiling the sw project.
However, when trying to boot from QSPI, I encountered the following error:
Xilinx Zynq MP First Stage Boot Loader
Release 2020.1 Jul 5 2023 - 17:32:44
Reset Mode : System Reset
Platform: Silicon (4.0), Running on A53-0 (64-bit) Processor, Device Name: XCZU5EV

XFsbl_SpkVer: XFSBL_ERROR_INVALID_EFUSE_SELECT

We are investigating the issue, and we will post here as soon as we have a fix for it.
Best Regards!
The respective tag corresponds to the latest 5EV release for the HELLO-WORLD demo project: https://github.com/Digilent/Genesys-ZU/releases/tag/5EV%2FHELLO-WORLD%2F2023.1. You can download the zip files and follow the corresponding instructions in the Genesys ZU Hello World Demo page, as an alternative to cloning the repo.
Regarding the wrong FSBL BSP optimization flag bug, from what I know this was an issue in an older version of Vitis, regarding the -Os optimization flag for the FSBL included in the HW platform. This has since been fixed in more recent versions of Vitis. The Xilinx FSBL optimization flags are mentioned here: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842019/Zynq+UltraScale+FSBL.
