dfuse endianness question
by Philippe De Muyter 09 Feb '26

09 Feb '26

Hello dfu-utils developers, I have just discovered dfu files and specifically DfuSe files, and I have read the "DfuSe File Format Specification" in UM0391 from ST. In UM0391, each buffer is "represented in Big Endian order". I have undersood that as saying that the 32bits value are stored in big-endian order. Now I see that dfu-utils expects and stores 32bits values in little-endian order. Is there another document that specifies that ? Best regards Philippe

DFU-util runtime vs DFU mode
by Bruce Doan 04 Jun '25

04 Jun '25

I am running DFU-util -d with my vid and pid for my device as parameters. The response is that the device is in runtime mode. When I use the update utility supplied by the chip manufacturer, the device programs and restarts (as per code in the bootloader) I cannot change the USB enumeration details at this point since too many devices have been deployed with existing bootloader code. How can I “fake out” DFU-util to accept a Vid/pid match and run the update? Please advise Bruce Doan

Zephyr DFU over USB Not Swapping
by Alexander Feldman 20 Aug '24

20 Aug '24

Hi, Could you please have a look at the dfu-util output and give me a hint on why what I'm doing is not working. Here is a description of the problem: I am using an NRF52840DK. 1. I erase the chip to start clean: nrfjprog --eraseall 2. I flash the MCUboot bootloader: ~/mcuboot/boot/zephyr$ west flash The output from the console is OK as there is no image: *** Booting MCUboot v2.1.0-43-g50f35144e4e4 *** *** Using Zephyr OS build v3.6.0-596-g9fa4cd8226ce *** I: Starting bootloader I: Primary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3 I: Secondary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3 I: Boot source: none W: Failed reading image headers; Image=0 E: Unable to find bootable image 3.

Greetings, I recently worked for a very large company as a contractor who sells Routers and internet based devices to companies and governments around the world. I noticed in the course of repairing these a line of code that appears and it had that this was copyright back in 2016. I tried looking online for the answer but I believe it's illegal to pass off something that isn't yours as copyrighted material. These machines they build all seem to run rather similar code and your codes seems to be in it. I have attached a picture i took of it. I wanted to make sure this is on the up and up because if not, they are clearly using your code for profit and passing it off as their own. I found they use a lot of github code/free code.

USB DFU found problem on STM32MP135F-DK in Microsoft Windows 10
by Piotr Lenarczyk 31 Mar '23

31 Mar '23

Dear Mr/Mrs, during work with ST Microelectronics STM32MP135F-DK board I have found, that after proper TF-A download there is a problem in dfu-util. Read USB DFU label is "UNKNOWN". This scenario is not reproducable under Linux dfu-util with the same set of software. I am not depended on this problem - it is informational only. Best Regards, Peter

Waiting for device with Arduino GIGA
by Matha Goram 30 Mar '23

30 Mar '23

Hello, This is not a bug and therefor I want to refrain from posting at the repository issues list. I'm running dfu-util to flash firmware to the GIGA board to start with MicroPython exercises. Here is the output: $ /usr/bin/dfu-util -w -a 0 -d 2341:0366 -D GIGAR1_MP_FW.dfu dfu-util 0.11 Copyright 2005-2009 Weston Schmidt, Harald Welte and OpenMoko Inc. Copyright 2010-2021 Tormod Volden and Stefan Schmidt This program is Free Software and has ABSOLUTELY NO WARRANTY Please report bugs to http://sourceforge.net/p/dfu-util/tickets/ Waiting for device, exit with ctrl-C ^C The ports on the desktop are: from ttyACM0 to ttyACM5 from ttyUSB0 to ttyUSB3 The GIGA is connected through ttyACM4 libusb version 1.0.26 (11724) I used dfu-util successfully (thanks to Tormod's advice) by setting the configuration rules for the USB port. Naturally, the port assignments for the GIGA board change in my environment but the Arduino IDE 2.4 correctly detects the right port for the board. Do I have to set the port (in my environment) while using dfu-util to flash the firmware? There is a port parameter but I don't know the correct way to specify the port. Also, I couldn't use the -l parameter to gain insight on the connected devices. Also, some clarification on the -a parameter would help my understanding. Thanks. Regards.

DFU-Util Capabilities
by Stuart Blake Tener 11 Apr '22

11 Apr '22

DFU Util users/developers, I am new to using this utility and would like to understand if it applies to any my use cases. Use case 1 I recently came into some USB flash drives that I wish to change the vendor id and product id on (they have bogus vendor id and product id numbers making them un-writable). Use case 2 I would also like to be able to examine the firmware from a USB stick (several years ago I was scammed on a USB stick I purchased that had a bogus capacity and had to argue with PayPal to get my money back). So it is surely not an unreasonable thing to wish to check a USB stick's firmware for that or other security purposes (passive injection of code to impact BIOS or the OS). Can this utility perform any of the aforementioned enumerated activities when used in a Linux environment? If not, any idea what would do so? Mailing list question - can this email list be commanded to send daily or weekly digests or should I expect a multitude of emails coming from individuals replying to threads? Thanks in advance and do stay safe (avoid the thugs) and healthy.

[dfu-util] UNDEFINED device listed with wrong PID:VID
by pierre.alaplantive.e＠sew-eurodrive.de 20 Jan '22

20 Jan '22

Hello, I am trying to load a bootloader on my LPC (NXP) microcontroller. I have installed LPCScrypt<https://www.nxp.com/design/microcontrollers-developer-resources/lpcscrypt-v…> and am using a script for it called boot_lpcscrypt.cmd where I call dfu-util -l in order to check if an NXP device in DFU mode is connected. I have it working on many computers but on multiple computers I get the following when I call dfu-util -l: C:\path\LPCScrypt>dfu-util.exe -l dfu-util 0.7 Copyright 2005-2008 Weston Schmidt, Harald Welte and OpenMoko Inc.

interessant: libusbx: debug [init_device] (bus: 1, addr: 34, depth: 1, port: 4): '\\.\USB#VID_1FC9&PID_000C#ABCD' libusbx: debug [init_device] (bus: 1, addr: 34, depth: 1, port: 4): '\\.\USB#VID_0B0E&PID_245D&MI_03#6&2C280BB0&0&0003' because USB#VID_1FC9&PID_000C#ABCD is my NXP microcontroller in DFU mode and I think USB#VID_0B0E&PID_245D&MI_03 is a Jabra Headset and for some reason they share the same configuration bus: 1, addr: 34, depth: 1, port: 4. Notice, that these are actually 2 different devices on 2 different USB ports. Then, from my understanding, dfu-util tries to open those devices with libusb_open, it works for USB#VID_1FC9&PID_000C#ABCD because it is in DFU mode: libusbx: debug [libusb_open] open 1.34 ... Found Runtime: [1fc9:000c] devnum=0, cfg=1, intf=0, alt=0, name="DFU" but not with USB#VID_0B0E&PID_245D&MI_03, which is a headset in normal mode. The output is: libusbx: debug [libusb_open] open 1.34 libusbx: debug [unsupported_open] unsupported API call for 'open' (unrecognized device driver) libusbx: debug [libusb_open] open 1.34 returns -12 I have 2 questions: 1. Shouldn't the output be corrected to give the correct VID:PID? to something like: Found Runtime: [0B0E:245D] devnum=0, cfg=1, intf=0, alt=0, name="UNDEFINED" 2. Is it correct, that USB#VID_1FC9&PID_000C#ABCD and USB#VID_0B0E&PID_245D&MI_03 share the same configuration bus: 1, addr: 34, depth: 1, port: 4 even though they are 2 different USB devices on 2 different USB ports? Is it a problem with dfu-util or with Windows? Can I fix this?
