F767: Firmware Upgrade using USB-host

HMSEdinburge · ‎2025-08-04

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

Firmware Update using USB Pen drive

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.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

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?
