-The board contains an onboard Microchip ATTPM20P-H6MA1-10 TPM connected to the SPI1 bus. 
-
-This is compliant to the Trusted Computing Group (TCG) Trusted Platform Module (TPM) Version 2.0,
-r116 Trusted Platform Module Library. See link here: [https://trustedcomputinggroup.org/ Link]
-
-Cryptographic Support for:
- - HMAC
- - AES-128
- - SHA-1
- - SHA-256
- - ECC BN_P256, ECCNIST_P256
- -RSA 1024-2048 bit keys
-
-It is controlled via generic TCG SPI Linux driver. TPM 2.0 provides direct access via /dev/tpm0 (with one client at a time), and can be accessed through the tpm2-abrmd resource manager daemon, or kernel-managed access via /dev/tpmrm0
-
-The TPM device is at /dev/tpm0
-
-The TPM tool set (over 100 different commands) can be installed with the following command:
-{{{
-apt install tpm2-tools tpm2-abrmd
-}}}

 The GW3089 incorporates onboard a USB to JTAG FTDI chip to allow JTAG programming of the unit without the requirement for a separate JTAG dongle (GW16099) which is typically used on other Gateworks SBCs.
