What should I use to hold the boot?

Can you tell me what the boot file is?
I would appreciate it if you could let me know.

Which 'bootloader' file should I use?

help me.

I don't understand your question?
What do you mean by "hold the boot" ?

STM32WB55CE supports USB DFU bootloader, review the relevant specs and docs

it doesn't need a separate bootloader.

Alternatively, get a st-link v2 and newer and program away
