    256 ** TPM / Crypto
    257 
    258 The board contains an onboard Microchip ATTPM20P-H6MA1-10 TPM connected to the SPI1 bus.
    259 
    260 This is compliant to the Trusted Computing Group (TCG) Trusted Platform Module (TPM) Version 2.0,
    261 r116 Trusted Platform Module Library. See link here: [https://trustedcomputinggroup.org/ Link]
    262 
    263 Cryptographic Support for:
    264  - HMAC
    265  - AES-128
    266  - SHA-1
    267  - SHA-256
    268  - ECC BN_P256, ECCNIST_P256
    269  -RSA 1024-2048 bit keys
    270 
    271 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
    272 
    273 The TPM device is at /dev/tpm0
    274 
    275 The TPM tool set (over 100 different commands) can be installed with the following command:
    276 {{{
    277 apt install tpm2-tools tpm2-abrmd
    278 }}}

    308262
    309263The 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.
