Hi,
I followed the instructions for installing the tpm_tis_spi driver for linux.
(https://www.st.com/resource/en/application_note/an5714-integrating-the-stsafetpm-trusted-platform-modules-with-linux-stmicroelectronics.pdf)
I built and load the kernel modules: tpm_tis_core and tpm_tis_spi.
from dmesg:
tpm_tis_spi: probe of spi0.0 failed with error -110
For some reason the TPM isn't responding to our spi communication.
How can I debug it?
Thanks
