For multi-byte input block readthe same for- embus is used for each individual byte read from the SMBus. Red Flag This Post Please let us know here why this post is inappropriate.

At the beginning of your post it sounds like you didn’t, msbus it sounds like you did The smbmsg utility has two different modi of operation. Because I’m afraid I won’t get any response here nothing negatives I also posted this thread in the C-forum Thread If no -c cmd option has been provided, the following messages can be issued: If a command value has been given using the -c cmd option, the following messages can be generated: This is done by sending each valid device freegsd one receive byte, and one quick read message, respectively.

For example, if a particular SMBus device considers any write operation issued to it as a request to power off the system, the probing would trigger this action.

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.
See below for a description. 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. Register now while it’s still free! Close this window and log in.
The second form shown in the synopsis can be used to send or receive arbitrary messages to or from individual devices. It supports IPMI ferebsd. This is working, but then find the BMC. Note that the SMBus byte order is defined to be little-endian low byte first, high byte follows.
This option is ignored in messages that do not read any input from the SMBus device. Also at the C-forum no responses And now I got really stuck, any help or ideas will be appreciated!

The data values to write are expected to follow all of the options and their arguments on the command-line, where the number of data bytes must match the outcnt value. Assuming this might be a Philips PCF real-time clock, this would stop the clock. Please post any helpfull information from now on in that thread. SMBus find devices Also at the C-forum no responses Want to link to this manual page? It looks more if the data returned is incorrect, and have nothing to do with the request.
Note that probing the bus is risky, since individual devices could per- form unwanted actions upon receiving one of the mentioned messages.

Since the low-order bit of the device address of SMBus devices selects between read and write operations, only even-numbered slave addresses freeebsd exist on the bus. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.
The only valid additional option for this modus of operation besides the -p option that choses the modus is -f dev.
