Hi.
I've got the following device: OPTIGA™ TPM SLx 9670 TPM2.0 with SPI Interface in a Raspberry Pi 3 (https://www.infineon.com/dgdl/Infineon-App-Note-SLx9670-TPM2.0_Embedded_RPi_DI_SLx-AN-v01_30-EN.pdf?fileId=5546d46267c74c9a01684b96e69f5d7b). I am trying to get the EK certificate but is seems that it is absent. I'm using the following command to fetch:

tpm2_nvread --index 0x1c00002 -a 0x40000001

I'm getting the following response:

ERROR: Tss2_Sys_NV_ReadPublic(0x18B) - tpm:handle(1):the handle is not correct for the use
ERROR: Failed to read NVRAM public area at index 0x1C00002
ERROR: Unable to run tpm2_nvread

Here is a list of all NV indices (empty):

pi@raspberrypi:~ $ tpm2_nvlist

Does Infineon have a EK certification server to restore the EK certificate? As far as I know this certificate should be already available but it is missing...

Thank you. Show Less
