Changing the user firmware address on NUCLEO-G491RE with Open Bootloader did not work

Hi, I am working with Open Bootloader and referring to a video tutorial for the same. While I am referring to this video I am not able to set the user firmware address from 0x08000000 to 0x08008000 as mentioned in this video following the same steps for NUCLEO-G491RE.

If I view the ELF file for a simple blink program on STM32CubeProgrammer looks like this

For Erase & Programming, it starts writing firmware from address 0x08000000 and not from 0x08008000.

What may go wrong?

If you need to change the start address you need to compile your firmware as a .bin file. It's not working with an .elf file. You can change this in the project properties. Please check "Convert to binary file".
