Hello,

If i understood correctly, you are expecting to connect external hardware TPM2.0 and it has to communicate with TI device.

This external interface TPM2.0 uses SPI protocol for communication, from TI perspective we have 8 SPI channels on Main domain core and 3 SPI channels on MCU domain core.

All the channels are accessible from all the cores.Now the question is on what core you want to process the TPM2.0 data ?

So it mean that all SPIs (on Main or MCU Core) can be used to process with external TPM2.0.

Thanks for your consultant...
