Diagnostic messages issued are supposed to be self-explanatory. When trying this with the folowing code I don’t get an result that make any sense???? Note that probing the bus is risky, since individual devices could per- form unwanted actions upon receiving one of the mentioned messages.
The smbmsg utility has two different modi of operation. The options are as follows: 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. 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.
If no -c cmd option has been provided, the following messages can be issued: This is working, but then find the BMC. It’s easy to join and it’s free. For example, if a particular SMBus device considers any write operation dmbus to it as a request to power off the system, the probing would trigger this action.

Either incntor outcnt or both must be equal 2 in this case. Close this window and log in. See below for a description. It looks 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. Please post any helpfull information from now on in that thread. Because I’m afraid I won’t get any response here nothing negatives I also posted this thread in the C-forum Thread This is done by sending each valid device address one receive byte, and one quick read message, respectively.
The data values to smbuss are expected to follow all of the options and their arguments on the command-line, where the number of data ffreebsd must match the outcnt value. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
Hi, What I would like to do is to read all kind of sensor data out of the BMC Baseboard Management Controllerlets take for example the processor temperature. Register now while it’s still free!

If a command value has been given using the -c cmd option, the following messages can be generated: Assuming this might freebsx a Philips PCF real-time clock, this would stop the clock. Since the low-order bit of the device address of SMBus devices selects between read and write operations, only even-numbered slave addresses frsebsd exist on the bus. Students Click Here Join Us! Not all argument combinations make sense in order to form valid SMBus messages.
For multi-byte input block readthe freebxd for- mat is used for each individual byte read from the SMBus. Did you get results running this?
