nrfutil dfu ble timeout

[nrbrook]

I'm attempting to use nrfutil with a nRF52 DK to perform dfu over BLE. The command I'm using and the result I get is:

% nrfjprog --eraseall                                       
Erasing user available code and UICR flash areas.
Applying system reset.

This is with the latest nrfutil 6.1.0, on windows or mac, the result is the same.

Hi, 

Try to add -f into the command to flash the connectivity FW as

nrfutil dfu ble -ic NRF52 -f -pkg app_dfu_package_1_1.0.0.zip

-Amanda H.

[nrbrook]

Ok it would be good if the error suggested that.

Now I have another error:

During handling of the above exception, another exception occurred:

edit: this only occurs on macos, it worked on windows.

Hi,

Can you try to use the full path to the COM port:

nrfutil dfu ble -ic NRF52 -pkg app_dfu_package_1_1.0.0.zip -f -p /dev/tty.usbmodem0006821181671

It worked for someone else having some problems with Mac and nrfutil. If it still cannot find the board, you might try to reboot the Mac and do it again. 

-Amanda H.

[nrbrook]

No, this results in the same error even after reboot

[Amanda Hsieh]

Please follow the steps outlined here http://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.4.0/zephyr/guides/tools/nordic_segger.html#disabling-the-mass-storage-device-functionality

The power cycle at the end is key for the change to take effect.

-Amanda H.

[nrbrook]

After disabling, unplugging, reconnecting and retrying I get the same error. I think this is probably a bug in nrfutil.

[Amanda Hsieh]

Please try the following command and provide the log if it cannot work. 

nrfutil dfu ble -ic NRF52 -pkg app_dfu_package_1_1.0.0.zip -f -snr 000682118167

-Amanda H.

[nrbrook]

This gets further, it connects to the device, but encounters another error.

nrfutil dfu ble -ic NRF52 -pkg package.zip  -f -snr 000682118167 --name "AirTurn D96D"
Board already flashed with connectivity firmware.

Hi Nick, 

It would be nice if you could run the command with verbose log level and provide the log again. Thanks.

Could you try to disable MSD in the Jlink driver and test again? You can follow this instruction: https://docs.zephyrproject.org/1.12.0/tools/nordic_segger.html#disabling-the-mass-storage-device-functionality

We have a similar case here and here that you may want to have a look.
