Requests for USB dongle without additional hardware. about opensk HOT 30 CLOSED

Thanks @Confined-
The workaround sequence will be:

./deploy.py --board=nrf52840_dongle_dfu --opensk --programmer=nordicdfu
<<<< Re insert the Dongle >>>>
./deploy.py --board=nrf52840_dongle_dfu --programmer=nordicdfu --no-app --dont-clear-apps

I can confirm this works !!!

from opensk.

I was able to compile and flash using the DFU method in my Mac.
My settings

1. python 3.7 or newer
2. install nrfutils using pip3
3. uninstall tockloder installed by OpenSK ( pip3 uninstall tockloader )
4. clone the master repository of tockloader and run setup.py install with python3. This will fix the App.get_binary issue
5. reinstall libusb: brew rm libusb --force & brew install libusb
6. and try again: ./deploy.py --board="nrf52840_dongle_dfu" --opensk --programmer=nordicdfu

Note: The dongle will be flashed and if you dont remove it form the USB you can run ioreg -p IOUSB and look for :
+-o OpenSK@14200000 <class AppleUSBDevice, id 0x1000277d6, registered, matched, active, busy 0 (0 ms), retain 12>
If you instead see:
+-o Open DFU Bootloader@14200000 <class AppleUSBDevice, id 0x10002776e, registered, matched, active, busy 0 (1 ms),
it means the flash did not work.

In my case, if I remove and re insert the dongle, it resets to DFU mode and I have to flash it again.
It looks like a known issue with some 'size' parameter during flashing.

Let me know if you have any question.

from opensk.

It seems that your version of nrfutil is too old and doesn't support python3 (iteritems is a python2 thing that got removed in python3).
Try to install a newer version by running the following command:
pip3 install --user --upgrade nrfutil

I haven't been actively documenting the DFU flashing yet because it comes with some quirks/limitations:

• when I tried installing nrfutil on my computer, it wasn't working because Nordic produced a broken wheel package for pc_ble_driver_py which is a dependency for nrfutil. Installing it on Linux required a bit of fiddling.
• the nrf52840 dongle may not be able to return to DFU mode once flashed (unlike the MDK dongle). I still have to check which pin Nordic used in their bootloader.
• I haven't tested it on other platforms than Linux at the moment.
• it requires to use Tockloader v0.4 which is not released yet. And once released, it's likely that some API/parameters have changed and that I need to adapt again the deploy.py script.

Hi;
I was trying to day with same and additional errors.
I also hit the ./deploy.py --board=nrf52840_dongle --opensk --programmer=nordicdfu fatal: This board doesn't support flashing over DFU. problem, and this is an easy fix in the docs ;).
The other problem is the python version needed. It looks like nrfutil will not install with python3. Installing it with python2 will bring other issues.

I was testing on OSX.
I will try with J-LINK EDU when it arrives

from opensk.

Hi
I'm very excited to see your reply, thanks!
I have installed pc_ble_driver_py.　It really It took me a long time, energy。

but ,there is a another issue. could you tell me how to reslove it ?

I find many methods.

from opensk.

• it requires to use Tockloader v0.4 which is not released yet

You said ,you use 0.4 version..Where i can find this version.
My tockloader is tockloader-master in github.

from opensk.

Could you flash tock os and app in your nordic 52840 dongle without hardware successfully?
Can it support flash without hardware currently?

from opensk.

First thanks!
My case is the same as your!
I can flash,and check it with ioreg -p IOUSB .
I want to know when i can flash and use it。Because that is so exciting!

from opensk.

According to this comment flashing Tock a second time is needed to prevent the dongle from entering DFU mode after reinsertion.

from opensk.

I just flashed with ./deploy.py --board=nrf52840_dongle_dfu --programmer=nordicdfu --no-app --dont-clear-apps after the initial flash. The key is now able to be removed and reinserted without being stuck in bootloader mode.

from opensk.

Interesting.
I will make some tests on my side and try to read the source code of Nordic bootloader to confirm this. And I'll patch the deploy.py script accordingly.

from opensk.

Thanks every one .
I can flash it and work normally!

from opensk.

so on ubuntu 18.04, is there a possibility to program the nrf52840 dongle over just usb wo needing special hardware or is that still unachievable?

anyone had any luck on non-mac so far?

from opensk.

Looking for same thing @ejeyaseelan. Seems like it is possible, don't see why it would be only Mac. Thinking of purchasing one soon to test.

This worked for me too. Thanks :)

from opensk.

@securewebsite Mac or linux? and what distro if on linux?

from opensk.

At the moment, we don't recommend to use DFU to flash a Nordic nRF52840 dongle because we haven't investigated how to go back to DFU mode once flashed.

If you don't want to use an external programmer, I suggest you pick a Makerdairy nRF52840 dongle. We added support for it too and this one can be forced to DFU mode by holding the button while plugging the dongle, allowing to flash newer versions of the firmware

from opensk.

The Nordic dongle has a reset switch near the main button, it is quite small and easy to miss. Pressing it while the dongle is plugged in will activate DFU mode. Definitely less convenient than the Makerdiary dongle but still works well enough.

from opensk.

Ok, that's weird because this didn't work for me when I tried.
I'll give it a second try and if this works, then I'll finish the proper fix for DFU flashing

from opensk.

@jmichelp looking forward to that!

if the softdevice from nordicsemi is incorporated into the nrf52840 dongle os + app package, then I am guessing pressing the button wont even be needed, most likely.

Thanks @Confined-

which os?

from opensk.

So, I got somewhere with this...

On Ubuntu 18.04 and using a particle debugger, I was able to program the nrf52840 dongle using the pyocd flash option in the deploy tool.

Now, i can login to a website simply by pressing the white button on thd dongle.

This works!!

Particle usb debugger $12usd, on sale.

from opensk.

can anyone confirm if one can use DFU without external hardware to flash Nordic nRF52840 dongle ?

from opensk.

You can do it with the workaround that has been mentioned (flashing everything, then flashing again the kernel only).
But you may not be able to flash an upgrade or go back to DFU. For this we need to fix a few issues but it won't apply retroactively of course.

We're working on improving the situation.

from opensk.

I have been unable to replicate the solution mentioned on Ubuntu. For now I'll just wait till it gets added to the deploy.py script natively 👍

which os?

I tested it on a MacOS with Catalina

from opensk.

I tried with the bypass and consistently got makefile errors (missing makefile.common). could be that i was running ubuntu live but I installed everything listed as necessary.

from opensk.

This is working for me but I needed to make a minor change to deploy.py as my tockloader was ver 1.5.0-dev.

def check_prerequisites(self):
    if not tockloader.__version__.startswith("1.5."):
      fatal(("Your version of tockloader seems incompatible: found {}, "
             "expected 1.4.x.".format(tockloader.__version__)))

I flashed first with

./deploy.py --board="nrf52840_dongle_dfu" --opensk --programmer=nordicdfu

followed by reinserting and then:

./deploy.py --board=nrf52840_dongle_dfu --programmer=nordicdfu --no-app --dont-clear-apps

and checked with

fido2-token -I /dev/hidraw3

minor: 0x00

I'm on Ubuntu 19.10. I also uninstalled tockloader and installed a git copy from tockloader's dev.

from opensk.

Is it okay now to use DFU to flash a Nordic nRF52840 dongle or are there still issues ?

from opensk.

Everything works ok, including fido2-token -L shows the device.
Running fido2-token -I /dev/hidraw0 the put hangs and never returns. Removing the key gives an error. I have both the white and yellow leds flashing at the same time when I insert - not sure what this means.

from opensk.

This issue is still present with the nRF52840 dongle or maybe a new issue. The work around of re-flashing Tock worked though.

The steps I took to get a working key.

Run lsusb and wait for the device Nordic Semiconductor ASA Open DFU Bootloader, try pressing the reset button.
First deploy fails with permission error (Probably can skip this and go straight to chmod).
./deploy.py --board="nrf52840_dongle_dfu" --opensk --programmer=nordicdfu
Should be able to avoid this bad idea by adding your user to the dialout group
sudo chmod a+rw /dev/ttyACM0
Works this time!
./deploy.py --board="nrf52840_dongle_dfu" --opensk --programmer=nordicdfu
Reinsert and press the reset button, wait for the DFU Bootloader device. Then grant permissions and flash.
sudo chmod a+rw /dev/ttyACM0
Reinstall Tock
./deploy.py --board=nrf52840_dongle_dfu --programmer=nordicdfu --no-app --dont-clear-apps
Reinstall keys followed this troubleshooting
./tools/configure.py --certificate=crypto_data/opensk_cert.pem --private-key=crypto_data/opensk.key
