The phyCORE-AM64x development kit provides a Trusted Platform Module (TPM) that provides hardware-based security functions. TPM technology is designed to provide hardware-based security functions. This guide will show you how to use the TPM to perform a hash on some data.

Confirming TPM Function

To perform the hash operation and get the resulting output run the following command:

Target (Linux)

 echo -n "test" | tpm2_hash -g sha256 | hexdump -C
