TRNG test example for Mbed OS

This is a test example of an application that uses the TRNG APIs.

The application invokes the TRNG APIs and prints the results after each such invocation, The test is composed out of three parts: the first, generate a trng buffer and try to compress it, at the end of first part we will reset the device. In second part we will generate a trng buffer with a different buffer size and try to compress it. In the third part we will again generate a trng buffer to see that the same trng output is not generated as the stored trng buffer from part one (before reseting), the new trng data will be concatenated to the trng data from the first part and then try to compress it together, if there are similar patterns the compression will succeed.

• An FRDM-K64F development board.
• An SD card.
• A micro-USB cable.

Although the board shown in this examples are K64F, the example should work on any device that support the trng feature.

1. Import the example.

   mbed import mbed-os-example-trng
   cd mbed-os-example-trng
   

2. Deploy mbed-os

   mbed deploy
   

3. Compile and run test.

   For example, for K64F with GCC:

   mbed test -t GCC_ARM -m K64F -n tests-trng-basic
   

4. The test should run and display a series of results following the StoragLite API invocations.

If you have problems, you can review the documentation for suggestions on what could be wrong and how to fix it.
