Different USB iProduct descriptors for DFU in different processors

[MButsch]

Hello,

We use a couple of different STM32's in our products and update them over USB via built-in the DFU bootloader.

I noticed that:

• for a STM32G491, the iProduct descriptor reports "DFU in FS Mode"
• for a STM32F302, the iProduct descriptor reports "STM32  BOOTLOADER"

Is there any significance to this difference or is that just differences in the bootloaders between the 2 models?

Thanks,

Mark

Should function the same. There are a lot of "different" system bootloaders to support all the various chips.

I agree they "should" function the same, but I am seeing different behavior with the two parts I mentioned when "leaving" DFU mode.

Just exploring obvious differences.
