DFU with NRF Connect (linux) write failure with unknown value (0x8005)

[Ramy]

Hi there,
I have been trying recently to DFU a custom device using desktop nrf connect, and I get an error message as in the following picture right after pressing start DFU

I'm using Ubuntu 18.04

as you can see nRF Connect is 3.3V, debugger is PCA10056 (nRF52840 DK)

from Log; Connectivity firmware version 4.1.1, SoftDevice API version: 3. baud rate: 1000000.

nrfjprog version: 10.5.0

JLinkARM.dll version: 6.60a

I've added udev rule, so I'm assuming that DK has permission

also please note that I've tried to DFU using same everything (DK, custom board, firmware same nRF connect version) but different windows 10 setup and it did worked ok.

in the Log, there was a message not showing also, Received status with code 4 Unknown value, message: "Error sending packet to target. Code 0x802a"

Hi,

I'm running the same Ubuntu version as you, but have not managed to replicate these two errors. Maybe you can try to disable MSD in jlink as explained here https://docs.zephyrproject.org/1.12.0/tools/nordic_segger.html#disabling-the-mass-storage-device-functionality    (remember to power-cycle the board as instructed before trying again)? I don't think this issue is related to permissions.

Hi,

I am getting the same error when I try to DFU my board, it seems coming from the nrf connect version 3.3 I recently updated..

I am using an nRF52840-DK  in version 1.0.0 and Windows 10,

nrfjprog version: 10.6.0
JLinkARM.dll version: 6.62a

Hi,

Even though you are on Windows, did you try to disable mass storage functionality on the Segger chip and power-cycle the board as I suggested? I managed to reproduce the same problem with my Windows 10 PC before I did that. Not sure if it was because of the MSD or if it had to do with the fact that I power-cycled the board afterwards. Either way, I suspect it has something to do with the Jlink. Maybe the recent Jlink driver update triggered this. I have not seen this with the nRF52840 Dongle, which uses the built-in nRF USB and not the Jlink USB.

I tried to power cycled the device and disable the mass storage functionnality in my device manager and it didn't change anything. I am not using any J-link, just the USB cable.

Do you have access to a nRF52840 dongle you can try with? The Jlink will act as a UART<->USB bridge unless you are using the nRF USB port next to the reset button.
