Dear All, We’ve use jump-wired between SOM’s SPI0(SPI1 with CS0 in SFIO) and TPM’s EVK. According vendor’s suggestion, the driver should use the tcg,tpm_tis_spi But the driver seem always feedback some error such as below. error code that should indicates I/O error ... [ 4.446732] tpm tpm0:…

Dear Sir, Apologize for these mess. The clock could generate with higher freqeucy. Our logic analyzer’s sample rate is too low that couldn’t fetch the higher clock at all. We’ve use the oscilloscope to fetch it. We’ve also validated the TPM SLB9670 with Xaiver NX and the a x86 platform for comp…
