)

It is not focused on final application's usage, even though there is a few hints in session3() function. Instead of that, this code mainly walks you through a different stages during a chip's lifecycle:

• Initial power up during PCB manufacturing
• Attestation key uploading
• Final product usage

Example shows how content of config objects might be used to set different access rights and how chip behaves during the device's lifecycle.

Note

We recommend reading TROPIC01's datasheet before diving into this example!

Warning

We strongly recommend running this example against the TROPIC01 model only, as it does irreversible operations!

Parameters

h

Handle for communication with TROPIC01. It is assumed that the h.l2.device and h.l3.crypto_ctx members were already initialized. Because these members are pointers, the assigned structures must exist throughout the whole life-cycle of the handle. Refer to the 'Get Started'->'Integrating Libtropic'->'How to Use' Section in the Libtropic documentation for more information.

Return values

0	Function executed successfully
-1	Function did not execute successfully
