Question on flashing firmware and bmc image

Question on flashing firmware and bmc image

[Pietro Maltoni]

[-- Attachment #1: Type: text/plain, Size: 719 bytes --]

I'm a student in university of bologna and for a research project I have to work with openbmc on a Tyan palmetto system.



I have successfully compiled and installed an openbmc firmware on the palmetto system following the guide https://github.com/openbmc/openbmc.

After installing it I've recognized that oem openpower commands and sensors are not available.

For instance when doing ipmitool sdr elist I do not see openpower sensors(occ ones) as well as netfn in ipmi does not contain commands for the occ.



By searching on the code I've recognized that these are in meta-openpower recipes. How can i enable them? Is there a standard procedure for enabling them on openpower hardware or in palmetto?

What is the revision of your build?
The ipmi related configs are not complete for Palmetto, and there is a
[recent commit][1] to add part of the sensors for ipmi.
With the commit, ipmi sdr elist works ok.
If you are looking to adding more sensors, patches are welcome!

And what do you mean by "netfn in ipmi does not contain commands for the occ"?

Please refer to the below link as an example of ipmi config for Palmetto's
sensors.

Thank for your reply,

Now i see the openpower sensors and if I issue the ipmitool  sel elist command I see the OCC represented as follow:

“
occ_3_0050       | 08h | ok  |  0.0 | Device Enabled
“


However when I try to issue ipmitool raw 0x3A command we do not get passthrough toward OCC, as it seems that the OCC netfn codes is not defined.


“RAW Commands:  raw <netfn> <cmd> [data]

Network Function Codes:

  VAL   HEX     STRING
==============================================
  0     0x00    Chassis
  2     0x02    Bridge
  4     0x04    SensorEvent
  6     0x06    Application
  8     0x08    Firmware
  10    0x0a    Storage
  12    0x0c    Transport
“

This is my version of BMC image

Author: Alexander Filippov <a.filippov@yadro.com>

And this is the pnor image version.

So what exactly netfn are you trying to use?
Please check the code in
https://github.com/openbmc/openpower-host-ipmi-oem/blob/master/oemhandler.cpp#L225:
only below netfn are implemented:
* IPMI_CMD_PESEL
* IPMI_CMD_PREP_FW_UPDATE
* IPMI_CMD_RESET_BMC_PASSWORD
