    worked on it again. This time with my own jffs2 base "littleOS" to not need to add the tty error workaround each time, and with the 3.6.1002 this time.
    i think i left the loglevel at 2 so there aren't any ecc errors but something is still not quiet right.

    Code:
    => run mlxlinux
    INIT: version 2.86 booting
    
    Starting: PPC_M460EX 3.6.1002 2016-06-09 20:24:26 ppc
    Starting udev: error initializing udevd socket
    Wait timeout. Will continue in the background.[FAILED]
    Setting hostname localhost:  [  OK  ]
    Checking filesystems
    /dev/mtdblock7: nonexistent device ("nofail" fstab option may be used to skip this device)
    /dev/mtdblock8: nonexistent device ("nofail" fstab option may be used to skip this device)
    /dev/mtdblock9: nonexistent device ("nofail" fstab option may be used to skip this device)
    Checking all file systems.
    [  OK  ]
    Remounting root filesystem in read-write mode:  [  OK  ]
    Mounting local filesystems:  mount: special device /dev/mtdblock8 does not exist
    mount: special device /dev/mtdblock9 does not exist
    [FAILED]
    Running vpart script:  [  OK  ]
    Applying file system skeletons: base_var base_config .
    Enabling /etc/fstab swaps:  [  OK  ]
    Remounting root
    Restarting system.
    
    thought that my fstab is wrong and borked for what ever reason but i have reedited twice and made shure not to **** it up by copy pasting weird characters into it.

    so i'm a bit lost right now

    Edit0: i forgot to downgrade the Kernel and FDT.

    Edit1: Pretty sure that THAT was the cause of the problems mentioned above.
    With the Kernel and fdt from the same version, it now manages to do the "fstab" and spit out tons of ecc errors after that. First Boot behavior.

    Edit2: Thank you all very much the help, it is now happily up and running

    Same here. Just tried to DL using JSL's link on page 8 but it no longer works. And mpogr seems to have left the building long ago. :(

    Any help with getting the SX6012 conversion files/info would be greatly appreciated.

    So I picked up a SX6036 and was looking to update the firmware etc...

    However when the switch showed up... its a SXX0 with REV A1

    Will this work with the firmware /update guide in this thread? Is there anyway I can check/test before i go past a point of no return?

    I'd hate to brick this just trying to update firmware.

    Thanks!

    -Levi

    Finding an EMC branded 6036 is supposed to be extremely rare. If what you have is actually a regular 6036 (mlx/hp/dell/Lenovo, running plain old mlnx-os) - don't try following the guide.
    There is a different set of steps for those. PM me for hints.

    There are 2 separate steps to making these EMC IB switches useful. The first step is actually replacing EMC software with a generic MLNX-OS build. The copy of the conversion guide I have seen was probably just a draft - somewhat convoluted and redundant. Yet it pointed me in the right direction and saved me a lot of time. So mad props to @mpogr for making it available. I did not keep a copy - because I did not think I would need it once I used the information to build my own custom image for flashing.

    The second step is enabling the ethernet gateway feature (without it you would still have an IB only switch). I tried the solution from the guide for the version 3.6.1002 and it worked. But in the end I decided to upgrade to the latest version so I got my proper license key elsewhere.

    So if you have a switch which is already running MLNX-OS - you can skip the first step.

    It's available in the MLNX-OS web GUI under Product Documents if you have a SX6012 running MLNX-OS.

    "My" method of conversion does the same thing as @mpogr's. So all the credit is still his. I just streamlined it a bit - integrated some of the manual steps into the OS image.

    Also I do not really use IB in my network - so I did not check if sm was working after ASIC but before my final OS upgrade. It is working now. I still have no use for it.

    I'm also having problems finding a working link to the .zip file that contains the conversion instructions and associated files mentioned above... can anyone provide a working link to the file?
    -Thanks!-
