Unable to perform DFU over serial and USB-serial

[Krupashankar]

I am using RIGADO Evaluation Board 320-00050 

I am using nrfutil v5.2.0 to perform DFU i am able to create DFU package and when sending the package i am facing problems

When i performed DFU over a serial UART connection i get following error:

raise NordicSemiException('Writing to serial port failed: ' + str(e) + '. '
pc_ble_driver_py.exceptions.NordicSemiException: Writing to serial port failed: WriteFile failed (WindowsError(5, 'Access is denied.')). If MSD is enabled on the target device, try to disable it ref. https://wiki.segger.com/index.php?title=J-Link-OB_SAM3U

i have disabled MSD also even then i get this error

When i performed DFU over a serial USB connection  i get following error:

self.mtu = struct.unpack('<H', bytearray(response))[0]
TypeError: 'NoneType' object is not iterable

Please help me out to perform DFU

Thanks,

Krupa

HI Krupa, 

are you running the Command Promt as administrator? 

Best regards

Hi Bjørn,

Yes i am using command prompt as administrator and i have tried without administrator also both didn't work

Thanks,

Krupa

Ok, the MSD issue appears to be specific to Mac OS X. Which OS are you running on the machine you'r running nrfutil on?

[Krupashankar]

i am using Windows 10 

[bjorn-spockeli]

Ok, pleas post the nrfutil command you're using to initiate the DFU procedure. Does the board enumerate as a COM port when you open the "Device Manager" in Win 10?

[Krupashankar]

Command used: nrfutil dfu  serial -pkg app_dfu_package_2.zip -p COM3 -b 115200

Yes device is connected and enumerated as com port 3

[bjorn-spockeli]

Ok, did you install nrfutil using pip install or did you download the .exe from https://github.com/NordicSemiconductor/pc-nrfutil/releases ? 

If you're not using the .exe, then please download that. If you are using it, then please run nrfutil with the -vvvv option, i.e. 

nrfutil -vvvv dfu serial -pkg app_dfu_package_2.zip -p COM3 -b 115200

This should generate a more detailed log.
