...or, perhaps, to avoid hacks and stupid stuff just add a console switch to disable timeouts or raise them :^)

Hi, The F767 datasheet for this chip says 8 (in some crazy parallel mode) to 32 seconds. Yeah if we force such a timeout, it would slow down the tool a lot for other, real chips (STM32F0 chips mass-erase in 30ms). Maybe if we add up the flash size from the memory segments, and if they are "large" (1MB) and the controller lies, then set the large timeout? Thanks! Ognjen

Tormod Volden — Tue, 03 Mar 2026 22:29:38 -0000

Then what if some other chip also reports 200 ms but doesn't need 35 seconds, maybe even correctly needs less than 200 ms? :) How many seconds does the datasheet say?

Ognjen Galic — Tue, 03 Mar 2026 22:17:12 -0000

Hi, Should that be added to the 35 second quirk perhaps? Br, Ognjen

Tormod Volden — Tue, 03 Mar 2026 22:15:16 -0000

Poll timeout 200 ms on command MASS_ERASE (state=dfuDNBUSY) The chip tells dfu-util to wait 200 ms before asking about status again, but that is probably too short and the chip is still busy erasing and not able to communicate so our get_status request times out.

Can you please format the STM32H7 output? You can see in the STM32F407 output: "Setting timeout to 35 seconds". This is a quirk because we know some devices report wrong erase time. Maybe the F767 also reports wrong erase time. Please use -v -v to see more debug information. You can also use -v -v -v but that is so verbose you'd better attach the output as a file.

No, I think the device is misbehaving. After receiving the "leave" request, it should answer the get_status request and actually only proceed to "leaving" afterwards. Which chip / bootloader is this?

The omission of the :leave option will also get rid of the error (but then the device will not be restarted). I am wondering if this is just a timing issue, that dfu-util is requesting the USB status before the device had time to restart.

It is not often that ELF files are used to provide firmware to end users as in this example. However it is often the primary build artifact so it would be convenient for development. It is interesting that StmDfuUsb supports ELF files because it is not mentioned on the home page https://yatrim.com/stmdfuusb I am not hugely in favour of adding all kind of file formats to dfu-util, because it adds complexity, maintenance burden and probably build dependencies. I would prefer it being added to the dfuse-pack.py...

You mention StmDfuUsb but not anything about what device and bootloader it is. Please see https://sourceforge.net/p/dfu-util/tickets/new/ You can convert the ELF file to a binary using objcopy. If it is a standard DFU 1.1 device then that's all fine, but if it a DfuSe bootloader you must know where to load it, this information is in the ELF file but not in the binary file.

I may have found the issue. In the script there are individual steps to programming the bootloader and application (the script being written by TI called usb_dfu_uniflash.py, in that scrip it checks the status of the target device using dfu-util -l between steps to check enumeration of the device to make sure it is ready for the next step.

I remember having seen, many years ago, an issue with a program running via Python's subprocess. I will try to recall or find back to it. You said that you added a lock that assures only one invocation of dfu-util is running at a time, but that didn't help. It therefore seems to me that the problem is not running dfu-util in parallel, but something else.

Hi Christopher, Just letting you know, we've encountered the same situation (can be reproduced on win11 and win10). Turns out new MS Teams are probing USB devices (presumably searching for communication devices to use) which triggers a request for device language ID descriptor from each connected USB devices. Since Xilinx (AMD) bootloader (FSBL) does not know how to handle this request, it goes into some weird state which causes DFU to stop responding. Issue can be mitigated by closing MS Teams....

dfu-util 0.9 is pretty old. You should try to update your Arduino board package for your board/device. I don't think the dfu-util version is the real problem, but newer versions are more helpful for debugging.

Sri, I mistakenly thought it was you posting as anonymous above. Your original problem is the same as in https://sourceforge.net/p/dfu-util/tickets/207/ so I will close this ticket. You can reopen it if you have more information. The anonymous posters can post in https://sourceforge.net/p/dfu-util/tickets/197
