Hi, I submitted a patch titled [PATCH] quirks: add AM261x device-specific manifest wait quirk approximately one week ago and received an automated notification that the message was awaiting moderator approval. The patch does not appear to reach the mailing list archives. Could someone please confirm whether the submissions is still pending moderation or if any action is required from my side? Thanks, Bensen Bernard.

[PATCH] quirks: add AM261x device-specific manifest wait quirk
by Bernard, Bensen 16 Jun '26

16 Jun '26

Hi, This patch adds an AM261x-specific quirk to reduce the manifest wait time to 500ms. The AM261x ROM DFU implementation resets before the default 1 second manifest wait expires, So applying the shorter wait enables reliable firmware downloads while preserving the existing behavior for all other devices Comments and feedback are welcome. Thanks, Bensen Bernard Texas Instruments

dfuse endianness question
by Philippe De Muyter 08 Feb '26

08 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 30 Mar '23

30 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 29 Mar '23

29 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.
