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 3.0=0x9ec43000 TPMEventLog=0x9711f018 [ 0.003517] ACPI: TPM2 0x000000009E490ED8 000034 (v03 LENOVO TC- S06 00001300 AMI 00000000) [ 4.071550] ima: No TPM chip found, activating TPM-bypass! Any ideas? Best regards Michael
