Firmware 1.3.1 update failed for nk3

[jasuarez]

I was trying to update my nitrokey3 from 1.2.2 to 1.3.1 firmware version using nitropy (0.4.36), but it fails:

Exception encountered: RuntimeError("generator didn't stop after throw()")

Afterwards, if I try to get the device status, it shows me no device found; I need to re-attach it.

Thanks for the report! It looks like this is the root cause of the rror:

Not sure what causes this. Have you installed a firmware update with that machine before? Is the error reproducible?

[jasuarez]

Yes, already upgrade the NK3 firmware to 1.2.2 with previous nitropy version (sorry, don't remember the version used).

I tried again multiple times, and everytime I get the same failure.

[jasuarez]

I've tried in a different host, and still the same issue.

For reference, I've installed nitropy with pip (pip3 install --user --upgrade pynitrokey) and my host uses Fedora 37.

[robin-nitrokey]

Can you please try installing pynitrokey in a virtual environment?

$ python3 -m venv /tmp/venv
$ source /tmp/venv/bin/activate
$ pip install pynitrokey

If this does not work either, please share the output of pip freeze (from the venv).

[jasuarez]

Didn't work neither

I installed the same versions but could not reproduce the problem. Please try the following steps to make sure that the bootloader communication works:

$ nitropy nk3 reboot --bootloader
$ nitropy nk3 list
# output should include Nitrokey 3 Bootloader (LPC55) followed by the UUID
$ nitropy nk3 update

[jasuarez]

Now it worked! Thanks a lot!

[robin-nitrokey]

Great! Though I’m not really sure what caused the problem. Please open a new issue if the problem happens again.

[jasuarez]

Not reopening this issue, but I keep having the same problem to update to v.1.4.0. Just following the steps to reboot first in bootloader mode worked.

[szszszsz]

Sounds like the problem still occurs. Let's reopen this one.

I’ve created a new issue with a more informative subject so that it is easier to find for users with a similar problem: https://github.com/Nitrokey/pynitrokey/issues/394
