Subject: [BUG] Nuvoton NCPT650 TPM 2.0 mode not working
Date: Sun, 11 Nov 2018 18:55:36 +0100 [thread overview]
Message-ID: <776f384a81466642472beb4a34b10f26f1de88e9.camel@mniewoehner.de> (raw)
Hi all,
Nuvoton NCPT650 does not work in TPM 2.0 mode with tpm_tis / tpm_i2c_nuvoton
while it works in TPM 1.2 mode (I can reflash it via UEFI setup).
Kernel version is 4.19.1
Kernel config:
$ cat .config | egrep 'TCG|TPM|CRB|_TIS'
CONFIG_TCG_TPM=y
CONFIG_HW_RANDOM_TPM=y
CONFIG_TCG_TIS_CORE=y
CONFIG_TCG_TIS=y
CONFIG_TCG_TIS_SPI=y
# CONFIG_TCG_TIS_I2C_ATMEL is not set
# CONFIG_TCG_TIS_I2C_INFINEON is not set
CONFIG_TCG_TIS_I2C_NUVOTON=y
# 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 is not set
# CONFIG_TCG_TIS_ST33ZP24_I2C is not set
# CONFIG_TCG_TIS_ST33ZP24_SPI is not set
TPM 1.2 mode dmesg:
$ dmesg | egrep -i tis\|tpm\|crb
[ 3.210040] tpm_tis 00:0a: 1.2 TPM (device-id 0xFE, rev-id 2)
TPM 2.0 mode dmesg:
$ dmesg | egrep -i tis\|tpm\|crb
[ 0.000000] efi: ACPI
2.0=0x9e457000 ACPI=0x9e457000 SMBIOS=0x9ec44000 SMBIOS

[ 0.003517] ACPI: TPM2 0x000000009E490ED8 000034 (v03 LENOVO TC-

[ 4.071550] ima: No TPM chip found, activating TPM-bypass!
Any ideas?
Best regards
Michael
