Error message using nRF Connect DFU Programmer

[SteveHx]

I have used the Programmer previously with success. I am attempting to program the Dongle (10059) with a slightly modified version of ble_nusc_usb_dongle. Although it claims to have completed successfully in 14 seconds, it halts with an error message in red in the log. Also I note that the memory map shown in the Programmer does not change.

Hello,

What kind of USB device does the dongle enumerate as if you unplug and reinsert it after the upload is complete? Does it indicate if the update was successful or not? I don't reckognize the error message at the end (the full message is not shown either).

Best regards,

Vidar

It enumerates as USB CDC, but that may be what it was previously programmed.

Let's try again for the full text of the error message. I have inserted a newline after each colon, since this web interface doesn't seem to handle automatic line wraps gracefully.

Thanks. This makes sense if you're reconnecting to the dongle after updating it with the NUS demo as the app does not have any plugin to interface with this type of device. The error would not have occured if the new app had support for buttonless DFU (nRF5 SDK DFU), or MCUBoot.  

[SteveHx]

Please point me to a document showing how to add that functionality, as I'd like to have it in this and a couple other applications, one of which is in a large-scale pilot deployment.

[Vidar Berg]

What functionality, buttonless dfu support with nRF5 SDK bootloader?

[SteveHx]

I'm probably not asking the question correctly. For now I jsut need to be able to run the USB CDC demo without getting an error message every time I download new firmware, and with some confirmation that it loaded correctly.
