I went looking for new firmware for this HCA. The OpenIB Wiki entry on 
updating the Mellanox firmware says to check the board revision by doing 

    "cat /sys/class/infiniband/mthca0/board_id"

which output nothing.  An "od" on the file shows only '0000000a' hex. 

Next I tried to find the board-id with the the "mstflint" tool as 
described in the "installation cheat sheet", but when I tried to build it 
under 'gen2/trunk/src/userspace/mstflint' I got a number of compile 
errors. Evidently this system's installation of gcc 3.4.3 is missing 
several 'c++' include files.  I will have to investigate that further.

So I next built the "tvflash" utility under 
'gen2/trunk/src/userspace/tvflash'.  I was able to use this to display 
some information about the board, but got an error:

[root at koa tvflash]# /usr/local/sbin/tvflash -i
HCA #0: Found MT25208 (MT23108 mode), Lion Cub, revision A0 (firmware 
autoupgrade)
  Primary image is v4.06.0000 build 3.0.0.160, with label 'HCA.LionCub.A0'
  Secondary image is v4.05.0000 build 2.0.0.572, with label 
'HCA.LionCub.A0'


Error. String Tag not present (found tag 4c instead)
  Vital Product Data
[root at koa tvflash]#

We have another identical system with the same type HCA, except that it is 
running the Cisco/Topspin 3.2.0 release stack instead of OpenIB.  The 
"tvflash" utility on that system gives:

[jatoba] (root) root> /usr/local/topspin/sbin/tvflash -i
HCA #0: MT25208 Tavor Compat, Lion Cub, revision A0
  Primary image is v4.7.400 build 3.2.0.67, with label 'HCA.LionCub.A0'
  Secondary image is v4.6.0 build 3.0.0.160, with label 'HCA.LionCub.A0'

  Vital Product Data
    Product Name: Lion cub
    P/N: 99-00026-01
    E/C: Rev: B00
    S/N: TS0448F00407

Lacking the Board-ID (PSID), I went to the Mellanox firmware support site 
and tried to determine what firmware I needed based on the information I 
did have (i.e. Lion Cub, PCI Express, 25208) and I think that I need to 
load the following firmware:

fw-25208-4_7_600-MHEL-CF128-T.bin.gz

Michael, can you confirm this, based on what I have described above?

Given the error I encountered trying to read the Vital Product Data above, 
will I be able to use the tvflash utility I built from the gen2 sources to 
succesfully update the board?

Does it look like my original problem is really the firmware?
