Custom OpenMV H7 plus board - flashing the boot loader

I am having a custom openmv H7 plus board developed. With a New chip do I need the debug port to flash it the first time with the bootloader or can load everything via the usb to PC connection?

Do I need any special programmers in case?

You just need to be able to short BOOT0 to 3.3V and have that hold when the board is powered on and plugged into USB.

You can then load the bootloader.dfu via USB. Then you can load our firmware.bin via USB. Use the IDE to load both files.
