F767: Firmware Upgrade using USB-host

Hello.. I'm designing a project using STM32F767 that upgrades firmware using USB Host 2.0. Could anyone advise on the following:

1. any application notes regarding the hardware pin connection, schematic diagram or any EVK board?

2. should i use USB_OTG_HS_DP, USB_OTG_HS_DM, USB_OTG_HS_VBus?

3. Should i use the 4 wire USB female connector? with these pins VCC, D+, D- , Gnd? Please advise soon, thx

As far as the USB Host goes, the fact that you're doing firmware update would be irrelevant - you're just pulling data from the inserted device.

On the Product Page for your chosen STM32F767, go to the 'Tools & Software' tab to find recommended dev boards.

hello Andrew...

That's DFU - which is device-side.

Or are you saying that you want your STM32F767 to be able to update a device that's plugged into it?

ie, update from the STM32F767 Host to a device plugged into it?

Can anyone kindly advise?

This is an example firmware of DFU application on F746. It should be the same implementation as Nucleo F767.

Maybe this application note could be helpful as well.
