And now I got really stuck, any help or ideas will be appreciated! I hope anyone has an answer Diagnostic messages issued are supposed to be self-explanatory.
See below for a description.
Skip site navigation 1 Skip section navigation 2 Header And Logo. It supports IPMI 2. Note that the SMBus byte order is defined to be little-endian low byte first, high byte follows. When trying this with the folowing code I don’t get an result that make any sense???? Hi, What I would like to do is to read all kind of sensor data out of smbks BMC Baseboard Management Controllerlets take for example the processor temperature.
The Tek-Tips staff will check this out and take appropriate action. Since the low-order bit of the device address of SMBus devices selects between read and smbuss operations, only even-numbered slave addresses can exist on the bus. Because I’m afraid I won’t get any response here nothing negatives I also posted this thread in the C-forum Thread This might be useful to explore individual devices on the SMBus, or maybe even to write short shell scripts performing maintenance operations on the bus.

Not all argument combinations make sense in order to form valid SMBus messages. Looking in the documentation it explains that the Device capabilitities field within the UDID frame which is returned in the smb frame should have the value 38 dec.
Note that probing the bus is risky, since individual devices could per- form unwanted actions upon receiving one of the mentioned messages. Register now while it’s still free! Also at the C-forum no responses At the beginning of your post it sounds like you didn’t, then it sounds like you did Any data values on the command-line are integer values in the range 0 through for byte values, or 0 through for word values.
Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Either incntor outcnt or both must be equal 2 in this case.

As far as I’ve found in the documentation the BMC can be accessed through two interfaces on this motherboard: The smbmsg utility has two different modi of operation. It freebed more if the data returned is incorrect, and have nothing to do with the request.

The second form shown in the synopsis can be used to send or receive arbitrary messages to or from individual devices.
