MCTP over I3C (Management Component Transport Protocol over I3C)
MCTP (Management Component Transport Protocol) over I3C lets system management controllers (such as BMC, EC, NIC, GPU) communicate over the MIPI I3C bus. Versus MCTP over I2C, it offers higher speed, lower power, and more flexible device management.
MCTP is transport-independent and can run over PCIe, I2C, I3C, UART, Ethernet, and similar layers. For channel-prefix differences, see Settings.
Decode Settings
- Channel: Assign SCL / SDA to logic analyzer channels.
- Destination Address Configuration: Set device addresses and corresponding protocols (opens the address table; Default restores the specification default address ladder).
- Advanced Decode Setting: Show detailed meaning of raw data. Field enabled (Enable) per protocol when checked. Default: Control / PLDM / NCSI / Ethernet / SPDM cleared.
- Control / PLDM / NCSI / Ethernet / NVME / SPDM / Vendor PCI / Vendor IANA
- SPDM Startup Setting: SPDM startup parameters. Default: Signature (S) 256, HashCnt (H) 2, Ext-AsymCnt (A) 1, Ext-HashCnt (E) 1.
