Hi tpm2 mailing list, I'm new here, so I briefly introduce myself. I am Florian, working at Siemens in Germany. I am currently on charge to implement a TPM V2 (Infineon slb9670, SPI connected) on our custom board, named 'LPE9403', equipped with an processor 64-bit ARM NXP LS1043a. I already made some adjustment (defconfig in U-Boot and Linux, device tree, init code in U-Boot). I have installed "tpm2-tools" using 'apt-get install'. I get to the point where the TPM is correctly detected and I can use some of the function like tpm2_getrandom(). However, when I execute the command 'reboot', it leads every time to a kernel panic. The logs seems to indicate that something went wrong with the shutdown of the TPM. Can you provide me support to fix this issue ? My config : - Processor 64-bit ARM NXP LS1043a - TPM V2 Infineon slb9670 - tpm2-tools: Version: 3.1.3-2 - linux kernel version: 4.19.144 I provide with this mail a zip archive 'debug_logs.zip' containing : - 'linux_logs.txt' : logs from Linux startup + kernel panic on reboot - 'uboot_logs.txt' : logs of the init commands in U-Boot - 'lpe.dtsi' : extract of the device tree used for the TPM - 'lpe_tfa_defconfig' : defconfig of U-boot - 'lpe9403_defconfig' : defconfig of linux - 'uboot_TPM_init_code.txt' : extract of the TPM init code in U-Boot - 'tpm2-tool_version.txt' : version of the installed tpm2-tools If needed, I can provide more information, Thanks for your support.
