Hi Einar
I am trying to perform DFU over serial UART of my board NRF52840.
whenever I am giving the command to perform serial DFU using nrfutil, I got the error given below:
2020-09-21 22:39:52,824 No trigger interface found for device with serial number: 6&2d471516&0&4, Product ID: 0x7523 and Vendor ID: 0x1A86
The command I isuued to for serial DFU is mentioned below:
nrfutil dfu serial -pkg hrs_application_s140.zip --port COM19 -b 115200
Thanks
Raj
Hi Raj,
There is some communication error, though it could be several things. You could try to change the flow control configuration and see if that helps, as suggested here. If that does not work, could you try to verify that the device is in DFU mode? One good way to check this (and other DFU problems) is to use a debug bootlaoder build with RTT logging, and observe the RTT log.
Hi Einar ,
As suggested in the link I disabled the fc(flowcontrol), But still I am facing the same issue, Below is the command & log I am getting atfer issuing command for serial DFU:
Command issued:
nrfutil dfu serial -pkg hrs_application_s140.zip -p COM19 -b 9600 -fc 0

Hi,
There may be an issue with nrfutil, as you should not normally get "No trigger interface found" for serial DFU, as that is USB specific (where there is a USB DFU trigger mechanism). I do not believe that is the root cause of the problem, though. It looks like there is communication issues, so I wonder if the nRF device is in bootloader/DFU mode?
Hi Einar,
>> I am uploading installSDKdirectory\examples\dfu\secure_bootloader\pca10056_uart this code to my nrf52 device, After uploading this code led 4 is continuously on.
>>UART communication is working well in normal condition without bootloader.
>>yes i configured the bootloader UART in the same way as the application.
