The title of article is that Infineon enables open source TSS ESAPI layer
It means that Infineon TPM 2.0 product can be used with open source TSS ESAPI layer. TSS ESAPI layer operate on Linux. And, it is already open source and can control any TPM product even though not Infineon TPM.
Now, when user use control AURIX and Arduino microcontrollers on Linux, it can be used to control Infineon TPM2.0 product on AURIX and Arduino microcontrollers after download open source TSS ESAPI layer.
(This SW is not provided from Infineon because of general open source to control TPM)
