create custom USB DFU program using libusb instead of STM32CubeProgrammer?

[m4l490n]

Hello,

First I want to clarify that STM32CubeProgrammer is a very cool and useful software.

The purpose of my question is that in my company we need to integrate a "Firmware Flasher" into one of our Software products since we are not going to indicate our customers to download, install, and use STM32CubeProgrammer to update their device's firmware.

I was wondering if there is a sample project or code that uses libusb (preferably in C or C++), that I can use as a reference to develop a firmware flasher. I say ideally in C and C++ but if it is not in any of these languages that is ok. I can just translate it from whatever to C++ using ChatGPT.

Thanks!

Try Github? Likely to be a place to find USB DFU code, ST or otherwise.

Perhaps you can find SW engineers with Windows, USB experience on places like Fiverr ?

Ok, I have heard about the USB DFU protocol before but I wasn't sure if the STM32 USB DFU implementation is just regular USB DFU or a custom version created by ST that they just called USB DFU.

I'll search for any USB DFU protocol examples. Thanks!

The ST implementation also is known as "DfuSe".
