I have a personal project, using a STM32F427ZGT. I flash by DFU, using STM32CubeProgrammer IDE without a problem. But I should program it by the terminal. I tried to use dfu-util without success.

It's an open source project, you might have to debug and maintain it yourself if the people working on it have moved on.

It's complaining about the signature, what's that look like? What created the .DFU?

Check ST's DFU format documentation

A .BIN is not in .DFU format, perhaps start there.

Hello Tesla DeLorean (Great name by the way).

Yes, the dfu-util is an open-source project and it is still maintained.

It also has become (as far as I know a standard to update firmware in USB devices).

The signature I think is related to the DFU USB device. The DFU that the errors are mentioned is related to the DFU device.

A Bin is a full binary with the firmware. In this Chip, the USB DFU Bootlader is implemented in hardware, not the firmware.

In fact, we manage to program a STM32F439 (on a nucleo F439ZI) via dfu-util.

I am starting to think if the STM32F427ZGT has some difference in DFU implementation when compared to STM32F439. I read something related to Dfuse, but didn't find a solution.

Thank you!

STMCubeprogrammer have CLI version with perfect compatibility with DFU.

Why you dont use it.

.DFU files are a special object file format. Typically generated by DfuSe or DFU Manager. In the past I've built direct packaging tools, like a HEX2DFU application.

They refer to this UM0391 document, but it's not findable as a direct link on their site.

I think STM32 Cube Programmer can perhaps side-step this and process HEX or BIN files into a protocol compatible format with regard to how it connects to the target STM32 in "BOOT LOADER" mode. You have to watch the VID/PID of the device if you've coded your own DFU Device firmware.
