F767: Firmware Upgrade using USB-host

[HMSEdinburge]

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.

Can anyone kindly advise?

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?

HI Andrew, i m using the USB DFU to upload, upgrade firmware (say a newer code, version 2, 3, 4...) into the F767 MCU..

In that case, the F767 needs to be a Device - not a Host.

Hi @HMSEdinburge 

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.
