Re: Simultaneous Firmware update and get sensor reading failing

@Patrick Williams<mailto:[email protected]>, Thanks for your response.

AMC - Auxiliary Management Controller card.

BMC is the master, and AMC is the slave in this context.

All the MCTP and PLDM implementations are based out of openbmc

Here is the link for pldm:

What is AMC?

Which code are you using for PLDM firmware update?  I believe there is an implementation still in flight in Gerrit within pldmd.

Hi Team,

I have been working on pldm firmware update and the pldm monitoring and control.

Problem:

I am performing AMC  firmware update  from bmc and then simultaneously requesting sensor data from AMC using GetSensorReading command. Both the commands get stuck at BMC's end and neither command is sent to AMC after that.


  1.
May I know whether we can pause get sensor reading?
  2.
What's the ideal time interval between two getsensorreading command?

And let me know if u any other suggestion to get rid of this issue.  It would be great to hear from the OpenBMC.
