DFU-Util Capabilities

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

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.

'\\.\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?

Bug in dfu-util?
by Steffen Breitbach 03 Mar '21

03 Mar '21

Hi everyone! I'm not sure what to make of this, so I thought it's probably a good idea to ask here first before filing a bug. I'm flashing a GigaDevice GD32VF103TB (Pinecil) with dfu-util0.10. I have compiled the latter from source, as there are supposedly some issues with 0.9 and that's not available yet. I have two machines, a Dell notebook and a Razer notebook. Both use the same USB3/Thunderbolt dock. With the Dell machine, I get this output every time I run dfu-util like this: sudo ./dfu-util-0.10/src/dfu-util -l dfu-util 0.10 [cut the disclaimer] Found DFU: [28e9:0189] ver=0100, devnum=17, cfg=1, intf=0, path="5-2.1", alt=1, name="@Option Bytes /0x1FFFF800/01*016Be", serial="3TBJ" Found DFU: [28e9:0189] ver=0100, devnum=17, cfg=1, intf=0, path="5-2.1", alt=0, name="@Internal Flash /0x08000000/128*001Kg", serial="3TBJ" However, when I connect it to my Razer, regardless of "directly" or via the dock, the behaviour is like this: FIRST run of dfu-util -l: sudo ./dfu-util-0.10/src/dfu-util -l dfu-util 0.10 [cut the disclaimer] dfu-util: Cannot open DFU device 28e9:0189 From that, I just get nothing at all, just as if no dfu device was connected at all. Looking into lsusb, the device is present before running dfu-util and gone after running dfu-util. Like I said, I have tested several connections, so my suspicion now is, that - for whatever reason - running dfu-util on my Razer makes the SoC "crash" so that it won't be recognized by the computer any more. However, I don't see a reason for this. I have checked the dfu-util binaries, they are identical. Also libusb versions and even the kernels are identical. So, I'm not sure this is a bug in dfu-util and I have no expertise in debugging this any further :( What could I do from here? Cheers Steffen

What is this device exactly? >From the above, your device seems to be a DfuSe device. In this case this is the expected behavior. I would recommend a DfuSe upload, specifying -s <address>:<length> The standard DFU upload offers no means for the host to request a certain length (or start), the device will simply transfer what should be the full firmware (or whatever payload that will be). If the host terminates the transaction prematurely, the result is undefined. In real cases the device will often hang or act up and must be reset. The -Z / --upload-size option name is a bit misleading, this only specifies an /expected/ payload size that will be used to scale the progress bar and nothing else. This was added because there is no way for dfu-util to know how long the payload will be. Some (all?) DfuSe bootloaders from ST seem to support a sort-of normal DFU upload, and will send back a payload without any hint of start address from the host. So I have preserved this functionality in dfu-util, more as a curiosity. However the bootloader doesn't terminate the transfer itself and my testing has shown that the bootloader will crash if the upload goes beyond the end of the flash memory. I therefore hardcoded a small size that I believe is safe for all devices. I should probably add a warning if this kind of upload is tried on a DfuSe device. Regards, Tormod

call for testing: dfu-util 0.10 RC
by Tormod Volden 27 Oct '20

27 Oct '20

Hi, I consider the current git head to be a release candidate for the upcoming 0.10 release of dfu-util, so I would be glad to see some testing on various devices. I have tested on STM32F4 and will test some custom IAP bootloaders. There are still known issues on STM32L4 and STMF0, but that has to wait for later releases. Thanks, Tormod

Just to update the list on this: After reviewing the DFU_UPLOAD specifications and what our --expected-size option does (simply scale the progress bar), we agreed to drop this patch.

Patch for activating --upload-size option
by Jakub Palider 05 Sep '20

05 Sep '20

Hello, please, review the patch and, if okay, apply it. It was tested with some basic scenarios for the upload size and results are backward compatible and work for relevant parameters: Use expected upload size when reading from device In order to limit transfer on wires stop transmission when expected size is reached.
