:name: MCTP Host Sample
|
|
|
|
Create an MCTP host over UART.
|
|
|
|
Overview
|
|
********
|
|
Sets up an MCTP node that sends a request on a UART targeting a particular MCTP
|
|
endpoint id with the message "hello". Expects and waits for a response to this
|
|
"hello" message containing "world".
|
|
|
|
Requirements
|
|
************
|
|
A board and SoC that provide access to a UART and a driver that implements the
|
|
UART async API.
|
|
|
|
Wiring
|
|
******
|
|
The UART pins should be wired to a board which will run the MCTP endpoint
|
|
sample such that this board's UART tx pin connects to the endpoint board's rx
|
|
pin, and this board's UART rx pin connects to the endpoint board's tx pin. The
|
|
boards' grounds should also be wired together.
|
|
|
|
Optionally a logic analyzer can be wired up and listening to the UART to inspect
|
|
the data flowing.
