How to flash examples to Dongle?

[qm3ster]

I bought a nRF52840 Dongle, to evaluate the use of nRF52840 for ZigBee purposes.

I have been able to flash such firmwares as \examples\peripheral\blinky\hex\blinky_pca10056_mbr.hex with the nRF Connect Programmer v1.0.1, however no LED flashing took place.

Others, like \examples\zigbee\light_control\light_bulb\hex contain just one layer and I cannot flash them this way, but I have been able  to flash them by doing 

nrfutil pkg generate --debug-mode --hw-version 52 --sd-req 0xAE --application .\nrf52840_xxaa.hex package.zip
nrfutil dfu serial -pkg .\package.zip -p COM12

Again, I get a dead device until I reset to bootloader.

What am I doing wrong?

Also, \examples\zigbee\experimental\cli\cli_agent_router\hex\nrf52840_xxaa.hex should show up as a serial port, right? In order to interact with the CLI?
(Because for me no such thing happens, no USB device until reboot to bootloader)

Ok, so the Dongle is actually PCA10059.
PCA10056 also uses the same nRF52840 SoC but is not the dongle.
Hence, I got the blinking working by flashing `\examples\peripheral\blinky\hex\blinky_pca10059_mbr.hex` with the nRF Connect Programmer graphical app.
This also worked for some other examples, like the BLE hexes that include a SoftDevice.

But I can't do the same with the nrfutil, because:

• I haven't been able to make a "dfu package" that doesn't require any SoftDevice. So if I make one from the blinking example, it demands the soft device be installed. And if I `dfu` it when the requires SoftDevice is available, it just puts the `blinky` `--application` after the SoftDevice, which makes it not work. So, how can I make a `package.zip` that doesn't require any soft device?
• When doing the same with a BLE example, it puts most of the `hex`'s contents, including a second copy of the SoftDevice, after the existing SoftDevice. Hence, once again the example doesn't work. How would I make it update just the Application sector from the `hex`?
  It is definitely possible, because loading this `hex` in  Programmer graphical application shows me the different sectors separately. (But possibly not implemented yet)

Hi Michail, 

If you want to update an application that doesn't require the softdevice, you can just use -sd-req 0x00. You don't need to provide any softdevice hex file. Then you can update the .zip normally.
