Hi Domining, Please check out this article.
https://prosauce.org/blog/2016/1/11/minnowboard-max-enable-and-test-the-firmware-txe-tpm-20 Also, there has been a person in the MinnowBoard GitHub issue tracker who successfully enabled TPM2 for this platform. See the thread here: https://github.com/MinnowBoard-org/bugs-and-help/issues/29 Thanks, Ulf From: <[email protected]> on behalf of Dominig Foll <[email protected]> Date: Tuesday, May 9, 2017 at 8:12 AM To: "[email protected]" <[email protected]> Subject: [yocto] how to activate tpm Hello, I am trying to get tpm working on a Minnowboard and a Joule. I have enabled tpm in meta-security. I can see that the Kernel config looks good (see extract bellow) tpm is enable in the BIOS (fails with TPM>PTT or dTPM 2.0) BUT i still cannot see my tpm device in /sys/class/tpm Has anyone succeeded to enable tpm with meta-security ? If yes, I would be interested to know how you have done. -- Dominig ar Foll Senior Software Architect Intel Open Source Technology Centre ------- log device not visible ---------- tcsd -f TCSD TDDL ERROR: Could not find a device to open! root@intel-corei7-64:~# modprobe -D tpm builtin tpm root@intel-corei7-64:~# modprobe -D tpm_tis builtin tpm_tis root@intel-corei7-64:/tmp# ls /sys/class/tpm root@intel-corei7-64:/tmp# --------- kernel config extract -------------- CONFIG_HW_RANDOM_TPM=m # CONFIG_NVRAM is not set # CONFIG_R3964 is not set # CONFIG_APPLICOM is not set # CONFIG_MWAVE is not set # CONFIG_RAW_DRIVER is not set CONFIG_HPET=y CONFIG_HPET_MMAP=y CONFIG_HPET_MMAP_DEFAULT=y # CONFIG_HANGCHECK_TIMER is not set CONFIG_TCG_TPM=y CONFIG_TCG_TIS_CORE=y CONFIG_TCG_TIS=y # CONFIG_TCG_TIS_SPI is not set # CONFIG_TCG_TIS_I2C_ATMEL is not set # CONFIG_TCG_TIS_I2C_INFINEON is not set # CONFIG_TCG_TIS_I2C_NUVOTON is not set # CONFIG_TCG_NSC is not set # CONFIG_TCG_ATMEL is not set # CONFIG_TCG_INFINEON is not set CONFIG_TCG_CRB=y CONFIG_TCG_VTPM_PROXY=y # CONFIG_TCG_TIS_ST33ZP24_I2C is not set # CONFIG_TCG_TIS_ST33ZP24_SPI is not set # CONFIG_TELCLOCK is not set CONFIG_DEVPORT=y # CONFIG_XILLYBUS is not set
