I'm using the nucleo-H753ZI board to test mcuboot.
The setup works and I can successfully run the bootloader and the application in slot0_partition using zephyr sysbuild.
However when trying to upload an image I get the following flash write error:
[00:00:29.758,000] <inf> mcuboot_util: Image index: 0, Swap type: none
