USB MSD/USB Stick example for STM32G4 Series

[ewilliams]

Hello, 

I have a STM32G4 evaluation board. My goal is to read and write to a USB thumb drive (pen drive/MSD device) using an STM32G4 microcontroller (bare-metal). 

When I look at the possible USB examples in the CubeIDE, I can't find any examples for MSD devices that are not obsolete and supported in CubeIDE.

Am I searching for the incorrect thing within CubeIDE?

Would you be able to point me to example(s) for this?

Thanks, 

Emma

There are videos about this in the USB Host section. See the description of this video:

To be able to do baremetal code, you can open the HAL functions and analyze the accessed registers.

Why would those board be obsolete?

But, AFAIK, the'G4 family uses a device-only USB, so you can't implement Host on it.

Choose a different family or a different solution.
