Good Day All...
I am embedded system architect and I am evaluating the SLB9673.
I was able to enable TMP2 recipe tools in our YOCTO build. I also enabled all necessary flags in our device tree. I created a image and it was able to start communicating with the chip.
so getting the chip to communicate is not the issue.
My current issue is how do I go to gain access to those 3 GPOI pins? does the TPM2 tools would be able get access to them?
Solved! Go to Solution.

Hi @EnriqueH_SLHC,
The GPIO’s of the SLB 9673 are implemented as specified in the Databook, chapter “General purpose I/O (GPIO)” and complies with “TCG PC Client Platform TPM Profile (PTP) Specification, Family 2.0, Level 00, Rev. 01.05 v14”, section 4.5.4.1 General Purpose I/O (GPIO).
