Output
NOTE:
The
i2ctool
does not automatically scan multiple MUXed segments. Before scanning, you MUST set the MUXes
to select the devices you want to see on the busses. By default, the
i2ctool
scans the
i2c
devices from the root MUX
where it sees the list of devices directly connected to the CPU MUX. The default scan function scans all connected busses.
By specifying a bus, you can limit the scan to one bus. In the scan data,
RR
indicates a reserved address which is not used
for any devices and
UU
indicates that the device is busy or mapped to the OS.
