I'm trying to get an "Infineon Iridium SLB 9670 TPM 2.0 SPI = Board" run on my Raspberry Pi 3. I have downloaded, compiled and insta= lled the latest versions of tpm2-abrmd, tpm2-tss and tpm2-tools. I started = tpm2-abrmd as root, hoping that I can then interact with the Infineon TPM u= sing tpm2-tools. "tpm2_pcrlist" and all other tpm2_* commands, ho= wever, return error "ERROR: Failed to initialize tcti context: 0x1&quo= t;.

Any ideas? Thanks!

No doubt. The first bit about providing additional data in bug reports / questions should probably land in the CONTRIBUTING.md files. A FAQ on the right wikis would be a good thing as well. With the churn in the TSS2 libs dying down I'll be refocusing on the tabrmd so I'll probably start there. If you've got the cycles and the motivation feel free to jump on the wiki and start adding content. Philip --===============8793028200071220832==--
