SPI TPM module support fail on jetpack 5.0.2/5.1 on jetson xavier agx

Hi b-sathishkumar

May I ask whether the TPM you use is SLB9670 or SLB9672?

Or is there a way to measure the behavior of the CS pin?

Because the problem we have is that when we use “nvidia,enable-hw-based-cs”, the behavior of the cs pin is not as required by SLB9672. We have confirmed this with Infineon’s FAE.

The waveforms we measured and the problems we encountered have opened another question on the following website, but no one has answered so far.

Best Regards
