Refering back to step 2 on the Linux box, here are the commands/debug/proof of what i used to make the jffs2 image:

Sx6012 or 6018 ,.
If it is 6012 only one mgmt port , why two Mac ?
If it is 6018 then wrong firmware

In this thread , some one post his mini image maybe @JSLEnterprises
This is from the 6012.

The reason I have two mac is because ifconfig (when booting from /dev/mtdblock6) reports 2 interfaces:

Code:
# ifconfig -a
eth0      Link encap:Ethernet  HWaddr F4:52:14:F0:CF:B6
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:41

eth1      Link encap:Ethernet  HWaddr F4:52:14:F0:CF:B7
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:43

lo        Link encap:Local Loopback
          LOOPBACK  MTU:65536  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

Regarding the mini image thread post, the link is dead.

somewhere there must be a mistake;) and given you have it everywhere it has be a structural error...

I'm at that step also. Would be great if someone could share the modified versions required. Or perhaps a point in the direction they could be found at would also help.

Thanks.

Could someone send me the conversion procedure? I haven't received a reply from mpogr since I sent him PM on Apr 27.

Thanks.

If I could get it as well that would be fantastic, maybe I can resurrect my 6018.

Hi,
I recently got the SX6012 switch (EMC version) and I am planning to flash it to the stock firmware according to @mpogr's instruction.
In the document I received, in Step 6, i am supposed to extract the firmware using HEX editor and flash the extracted firmware (.bin) file to switch via "flint" command. It doesn't say where I should run the command, i assume i have to execute it via a desktop connected to the switch (with ConnectX adapter and Mellanox OFED tools installed). Is it correct?
Before I start to perform the processes, i am verifying if the switch can be identified by my desktop (the adapter is HP_0280210019).
I boot the switch into untouched EMC OS and used a DAC cable (QSFP port) to connect my adapter and switch and I can see the link is up with FDR rate. Also I can use "iblinkinfo" and "mst status" command to verify the switches can be seen from the desktop with lid 2.

Code:
[root@aurora ~]# ibswitches
Switch  : 0x248a0703007ed300 ports 12 "SwitchX -  Mellanox Technologies" base port 0 lid 2 lmc 0

[root@aurora ~]# iblinkinfo
Switch: 0x248a0703007ed300 SwitchX -  Mellanox Technologies:

           2    4[  ] ==(                Down/ Polling)==>             [  ] "" ( )

           2    7[  ] ==(                Down/ Polling)==>             [  ] "" ( )
           2    8[  ] ==(                Down/ Polling)==>             [  ] "" ( )

           2   10[  ] ==(                Down/ Polling)==>             [  ] "" ( )
           2   11[  ] ==(                Down/ Polling)==>             [  ] "" ( )
           2   12[  ] ==(                Down/ Polling)==>             [  ] "" ( )

But then I got problem, it seems command "flint" is unable to query to switch's information via following command.

flint -d lid-0x2 q

The command ends with error:
Code:
[root@aurora ~]# flint -d lid-0x2 q
-E- ibvsmad : cr access read to Lid 2 failed
-E- ibvsmad : cr access read to Lid 2 failed
FATAL - crspace read (0xf0014) failed: Invalid argument
-E- Cannot open Device: lid-0x2. Invalid argument. MFE_GENERAL_ERROR
I wonder if there is any issue here. Or I missed anything.

Anyone using their switch to route between vlans?

I'm having to ping a device from the switch before I can ping it from the other vlan, it then works finde for a time and then I have to do it again.

I'm thinking it has something to do with ARP, but I'm not sure.
