wolfTPM Version 1.8 has been released and is now available for download on our website. This release brings new platform support for Xilinx Zynq UltraScale+ MPSoC and new operating environment support for Linux users. We have now tested with two more TPM modules, the Nuvoton NPCT650 and NationsTech Z32H330.
To reduce the time needed for new applications on Linux we’ve added support for the Linux TIS kernel driver (“/dev/tpm#”). This allows applications using wolfTPM under Linux to exist alongside the Linux TPM tools. It also makes it easier for users to leverage existing Linux TPM module and LPC bus support without the need for additional system configuration.
The default build-behavior is to use the “/dev/spidev#.#” directly via the HAL IO callback. To enable the “/dev/tpm#” support use the “./configure –enable-devtpm” build option.
This release also resolves some build issues with the crypto callback support for TLS and adds examples for using an ECC primary storage root key.
