OPTIGA™ TPM Forum Discussions

Hi

I'm working on secure boot on TI omapl138 soc  using TPM1.2 slb9645, I am able to detect TPM chip through I2C, But i didn't get any data sheet or technical reference module to  know  how  TPM 1.2 works and register/memory addresses, To develop further can you please provide detailed documents  of TPM 1.2 slb9645.

Thanks & regards

Hi @snehapra 
Continuation to my last query,

https://community.infineon.com/t5/OPTIGA-TPM/TPM2-0-SLB9670VQ2-0-bringup-in-uboot2016/m-p/360316/emcs_t/S2h8ZW1haWx8bWVudGlvbl9zdWJzY3JpcHRpb258TDVURzcxRkNXVEJNVEZ8MzYwMzE2fEFUX01FTlRJT05TfGhL#M93

Is there any patch available for TPM2.0 implementation in u-boot 2016, what snehapra has suggested, in the above link, is for u-boot v2022.

Another question is, available tpm2.0 code is based on Driver model or not ?

Thanks,

Hello All,

I'm trying to bringup TPM2.0-SLB9670VQ2.0 in "uboot2016" for IPQ8072 qualcomm chipset.

Would be great if some one pls share some docs/references  or pointers.

thanks in advance..

Hi Team,

Does Infineon have a TPM module which is FIPS 140-3 compliant or certified? I currently use SLB 9670VQ2.0 which is FIPS 140-2 certified and would like to move to FIPS 140-3.

Thanks and Regards,

Hello, everyone, I bought an evaluation board iridium 9645 ( IRIDIUM9645TPMI2CTOBO1), with an SLB9645 TPM 1.2, but I can't find any datasheet to plug this board on a raspberry pi 3B (40 pins header). Could you provide the datasheet? If there is no datasheet, could you tell me what is the interest of the two jumpers, the 28 pins header, the 6 pins headers? The 26 pins header for raspberry? Where should I plug it on the header of my raspberry pi 3B, and in what way should I plug it?

Regards,

Hi Infineon Team,

I'm trying to interface TI omapl138 soc with TPM1.2 slb9645 through Driver module (DM)_I2C, But facing problem with integration via U-boot not able to detect TPM chip on I2C bus. I'm looking for a U-boot driver/source code to interface TPM1.2 slb9645, Presently I am using U-Boot 2018.01.

Thanks & regards,

Hi

Good day.

We have programming requirements for  SLB9665 and SLB9670, and we are evaluating to implement TPM programming/provisioning to our programming systems. We have HSM and CA server, and we need the more detail information about LPC/SPI protocol and programming flow to implement. We have tried to find the source code from github, but it seems based on the OS to execute the IC provisioning.

         May i know any documents about the detail (protocol and flow and command..) for third party?

Thank you.

Jack

I am using HW with TPM module and with RHEL OS installed

We have binded password with Luks, so that we dont need to enter password on every boot.

when multiple abrupt power cycle happened, the TPM module got locked. I think DA lock happened. 

1. How to come out from such lock out and recover automatically?

Is there any concern if OPTIGA TPM SLM9670 is located on a SPI bus, where other ICs such as SRAM and flash memory are connected to a CPU? SCLK, MOSI, and MISO signals will be driven even when CS# for TPM is negated. Is this OK? 

Please kindly advise. Thanks,
