No crypto present

Hi,
I have this error, I tried to reset it but when I configure it, in step 3 I get this error.
I don't know what to do to make the NANO33 IoT confugrable.

Do you have something connected to the i2c bus of the board? Can you please try to run this example?

Thank you, I will try your sketch.

It gives me this error:

Hi @eziogi it looks like there is some issue in your local setup. You could try to remove and reinstall your Arduino SAMD Boards core using the board manager of the Arduino IDE.

Then you should be able to compile this sketch without issues.

Thank you for your help.

Hi pennam,
I still get the error " no crypto present" in the Arduino NANON 33 IoT if I try to configure it when I want to use it in the IOT.
If I install and launch the sketch recommended, I see in the monitor this error:

Failed to communicate with ECC508/ECC608!

I don't know what to do to be able to use NANO33 again.
I need some help.

Hi @eziogi. Please answer this question:

By "i2c bus", @pennam means pins A4 and A5 on the board.

Hi,
no, I'm using the NANO without any pins connected except for the wire that goes to the MAC's USB.

Hi,
I'm here for your same issue. Have you found a solution meanwhile?

I simply deleted and then reloaded Arduino IoT cloud.

I'm sorry but isn't Arduino Cloud a webpage? What do you mean when you say deleted and reloaded? I'm sorry but I'm new into this. Thank a lot!

I had the problem with a Mac and a NANO33 IoT.
First I deleted the installation of the Arduino Cloud Agent.
Then I installed it again and it started working again with the other NANO33 IoTs I have, except with one that kept giving me the problem.
Then I realised that the problem was the device, not the 'Agent' application, so I use this NANO as a simple non-IOT device and it works.
I can't tell you anything else.
