Thank you for competent help and wish you a nice evening

Hmm, thats weird. If you flash the USB bootloader only, does the COM port disappear if you manually reset the nRF52840?

i chanced it in the sdk_config.h like this :

#ifndef NRF_BL_DFU_CONTINUATION_TIMEOUT_MS
#define NRF_BL_DFU_CONTINUATION_TIMEOUT_MS 100000
#endif

now i have 100 sec but it still doesn't work.

After the chance the COM11 disappears immediately after restart

Ok, what is NRF_BL_DFU_CONTINUATION_TIMEOUT_MS set to in the bootloader you are using? It by default set to 10 seconds I think. You could try to increase this to see if this allows nRFutil to send the application image after the SD has been updated.

after the reset the nrf52840 is still in the bootloader for about 30 seconds and after that it changes to the serial interface com12 (which is the old application)

Thanks for the log file and log output. So it seems that nrfutil cant find COM11, can you check in your Device Manager that the nRF52840 is still enumerated as COM11 after the reset between the SD and APP transfer?

Can you try to add -o after the -vvvv option? I think that should solve the issue with the no such option -o error

nrfutil -vvvv -o nrfutil_logfile dfu serial -pkg app_dfu_package_softdevice.zip -p COM11 -o nrfutil_logfile

Hey Bjørn,

I messed it up with the output file but with nrfutil dfu serial there is no -o. I tried the command from you but it did not generate an output file is there another way to generate such a file?

Greetings and thanks for the quick reply
Lukas

Hi Streitler,

when performing a combined SD+ APP update, the DFU process will be done in two consecutive updates, where the nRF will reset in between. This is stated under DFU package combinations.

⁴The SD (+ BL) + APP update is done with two consecutive connections, unless a custom bootloader is used. First the SD (+ BL) is updated, then the bootloader will disconnect and the (new) BL will start advertising. Then the second connection to the bootloader will update the APP.

So the fact that the nRF52840 is resetting is expected, but the second transfer should start after the reset. Could you run nrfutil with maximum verbosity and log the output to a file using the -v and -o options, i.e.

nrfutil -vvvv dfu serial -pkg app_dfu_package_softdevice.zip -p COM11 -o nrfutil_logfile

and then upload the nrfutil_logfile.log file?

Best regars

Bjørn
