hi
yes
bootm ff600000
it gets to a stage where ABCD comes up on the terminal.. then it just stops
i also tried to burn it using flint etc. but it says the .img is corrupt. i usually only use .bin files for burning firmware as far as i know.
does anyone know how to upload this file without a working mlnx-os running?
Stuck....
Okay!
I have a experience that I recover my old 4036 switch on u-boot console. There is seversl scripts.
Unfortunately I can'n remember exact command for 4036...:(
But I think there is self rebuild script to build a default boot environmrmt include firmware loading procedure. If you can connect serial concole, when a message that press any key to stop normal boot or etc, press any key then you will be on u-boot console. ? or help + enter shows u-boot command lists then you can try search command that I said above.
Good luck...:)
hi
yes ive been reading th u-boot manual, and looking for forum posts on how to use it.. its rather messy.
I have all the commands, but there isnt any command like the one you suggest
? - alias for 'help'
autoscr - DEPRECATED - use "source" command instead
base - print or set address offset
bdinfo - print Board Info structure
boot - boot default, i.e., run 'bootcmd'
bootd - boot default, i.e., run 'bootcmd'
bootm - boot application image from memory
bootp - boot image via network using BOOTP/TFTP protocol
cmp - memory compare
coninfo - print console devices and information
cp - memory copy
crc32 - checksum calculation
date - get/set/reset date & time
dboot - Digi modules boot commands
dcache - enable or disable data cache
dhcp - boot image via network using DHCP/TFTP protocol
echo - echo args to console
envreset- Sets environment variables to default setting
erase_pt- Erases the partition
fatinfo - print information about filesystem
fatload - load binary file from a dos filesystem
fatls - list files in a directory (default /)
flpart - displays or modifies the partition table.
fuse - Fuse sub system
go - start application at address 'addr'
help - print online help
i2c - I2C sub-system
icache - enable or disable instruction cache
iminfo - print header information for application image
imxtract- extract a part of a multi-image

itest - return true/false on integer compare
loadb - load binary file over serial line (kermit mode)
loads - load S-Record file over serial line
loady - load binary file over serial line (ymodem mode)
loop - infinite loop on address range
md - memory display
mii - MII utility commands

rarpboot- boot image via network using RARP/TFTP protocol
reboot - Perform RESET of the CPU
reset - Perform RESET of the CPU
run - run commands in an environment variable
saveenv - save environment variables to persistent storage
setenv - set environment variables
sleep - delay execution for some time
source - run script from memory
sspi - SPI utility commands
tftpboot- boot image via network using TFTP protocol
update - Digi modules update commands
usb - USB sub-system
usbboot – boot from USB device
version - print monitor version
my understanding is
there is 2GB of volatile system ram used for kernel processes
1GB SDRAM for local storage (where mlnx-os .img file lives (240MB in zise) this is the JFFS2 file system.
16MB or Flash ROM for Uboot, and 2 main boot partitions for Linux Kernel
you can boot from USB, NFS, SFTP, or FLASH, or SDRAM. though the ram addresses on the mellanox system are different from the example of the u-boot manual (as it uses smaller system with less ram etc) you can programm the boot partiotion using setenv command.
U-boot brings up serial, cpu, network and pcie bus, then boot selection is supposed to boot into Flash boot partition, where mlnx-os kernel is supposed to live.
So, i have the mlnx-os.img file (about 240MB) and can upload that to the NVRAM
but i need a linux kernel to load into the Flash ROM... anyone have a copy?
could you be talking about thebootscrips command?
ill try to boot the image using direct booting...?
Can you capture the result of printenv command?
My old 4036 have a shows like below...:)
.
.
build_flash=run upd_uboot && run upd_all && run upd_all_safe &&echo burn process succeeded
.
.
hi
no there is nothing in the printenv like that.
there are alot of variable and settings, perhaps u-boot itself has become corrupt. though
i have just noticed the message in the u-boot process
"PCIE0: link is not up
PCIE1: successfully set as root complex
01 00 1fb3 c738 0c06 00
Net ppc_4xx_eth0, ppc_4xx_eth1
so im stumped. perhaps the pcie0 bus is failed. though i know the Flash is corrupt. so could be faulty board.
?????
Hi! again...:)
I review your article again on my PC...:)
Last was my iPhone 6s Plus.
Do Not UES setenv command!
That's a very dasngerous that cause problem normal u-boot procedure!
There is a 3 command about boot environment
1. envreset- Sets environment variables to default setting
2. saveenv - save environment variables to persistent storage
3. setenv - set environment variables
If you setenv command A=XXX then last other configuration will be gone!
You must setenv command with full configuration options.
I think you must envreset then reset CPU and try again.
What's your switch model?
I think some advanced in latest Mellanox product, but u-boot logic is same old one.
I can find this 2 commands on your dump above.
1. autoscr - DEPRECATED - use "source" command instead
2. nand - NAND sub-system
3. nboot - boot from NAND device
All Mellanox switch have same construction.
NAND on switch will be partitioned 2 exasperatedly then boot from one of them
Can you dump help of this 3 commands? - autoscr, nand, nboot
hi
yes we had same problem with firmware 2.7 on MHRA2A-XSR and MHQH29-xtc cards, upgraded to 2.9.1 and had similar issues.
basically the firware and drivers dont work together very well. If you use generic OFED not MLNX OFED there are many issues with cards not working in linux (centos/ubuntu and vmware)
Mellanox OFED for CENTOS 7.1 works well on CX3 Cards, but same issues above arise on older cards.
the only effective solution we found was to upgrade to all new cards - PCIE3 CX3 VPI cards, like the HP 649281-B21 works very well, also the IBM mezzaine cards for M5 Servers is very fast and stable on the new Firmware. Driver support is strong @ 3.4.1000 for IBM and HP cards. We have multiple IBM 3650M4's and M5's + some HP g8's
or go with mellanox MCX353A-FCCT MT_1100111019 cards as they have Ver 3.4.6xx - you wont regret the investment. We get about 30-40% increase in raw SRP speed!
For production we have now ratified CX3-VPI cards to work with VMWARE ESi5.5 but not 6. we tried iSER but found it to be slower than SRP. We have a custom SRP ALUA driver we built for ESXi 5.5 on SCST. And have a SRP RAID network, which pushes 32GB/s easily! per switch. MPIO shows 45GB/s over dual 56Gb/s Switches.
Once we can afford EDR well upgrade again, and should be pushing massive SRP speed for block i/o.
Also we cant get SR-IOV to work on VMware which is a real problem, but from posts here it looks even slower than fullspeed iSER.
So from experience, get the latest cards you can afford!
hi
yes ive been very carefull not to adjust any commands saved in env
those commands all work.
switch is a SX6012 or SX1012... 12 port FDR
the firmware is ok, and i can query the switch from IB, and get ports up using opensm on linux host ok
Switch : 0x0002c90300ad6280 ports 12 "SwitchX - Mellanox Technologies" base port 0 lid 2 lmc 0
just seems to have corrupt boot partitions.

Also boot of uboot shows
U-Boot 2009.01 SC_PPC_M460EX SX_3.2.0330-82 ppc (feb 27 2013 - 12:13:04)
Security/Kasumi support
In theory, one should beable to copy using mem command from FF40000 or FF60000 on a working switch > TFTP.
I could then download that image file and get the switch to work. Once i figure out where to copy the .img file Mellanox have provided. (the inline firmware image for mlnx-os update command, i should beable to figure that out from the kernel once its running).... not to repeat myself, but to be clear. The current image files on each of the 2 partitions are corrupt. thus i cant boot a linux Kernel.
Anyone willing to boot to u-boot and download a copy for me. once i have it i can copy it to FF400000 and FF600000 boot partitions, hoping the partitions are ok.
Cheers
Hi,
I am new to using mellanox switches.
i want to use mellanox infiniband switches for my rocks cluster.
I want to know about the HPC-X softwares. do we need to purchase its license or it's free.
there are some packages are in HPC-X like FCA, HPC-X Toolkit, MXM, HPC-X MPI, HPC-X OPENSHMEM, HPC-X UPC
if we purchased HPC-X all of the packages are comes by default or do we need to purchase it separately.
Also if we need job scheduler for my cluster are it is in HPC-X if yes which one I can use.
Please let me know.
Thanks,
Rahul
Is there any ethernet port? - console port! -
If not it is a SX6005 FDR switch that externally managed that doesn't include SM.
SX6012 is a FDR switch with SM.
Your dump shows a word LID...:)
I think you have a InfiniBand switch - not ethernet switch -
You said that you used flint that can flash firmware only - not boot image.
I think also clear boot bank on NAND then re-program include re-partition and upload each boot images.
Custom or any 3rd party image uploader can't support like Mellanox's done on their platform.
Unfortunately I don't have Seitch-X product yet...:(
But you will be recover boot bank on u-boot console by my experience...:)
Don't give it up!
Have a nice day...:)
Hi Rajesh,
I know only about 1 public network auto installation via Fuel.
Anyhow, Public / external networks are under Mirantis development and maintenance, so I think it's better to ask in Questions : Fuel for OpenStack .
Please put me as a subscriber in the question in Launchpad, I don't think there should be any special driver issues with doing so, since you have the others networks working over our interfaces.
Mirantis connects the private networks to a router with a gateway to their (only) public network, so you need to think about this point IMO.
Another option is just do it manually, but it's not so scalable...
Let's try the LP channel - let me know if you need any help with posting the question,
Aviram
Hi,
Did you try to check on HP site, what is supported configurations? I'm not sure which OS you running, so can't tell what should it be. However, I believe this link might help
Drivers & Software for HP NC542m Dual Port Flex-10 10GbE BL-c Adapter - HP Support Center.
Did you try to run smaller jobs size?
May be status filed in event will tell more about the error?
There is no command that will retrieve switch serial number via in-band links (from an unmanaged switch).
If it was a managed switch (which would have CLI access), the "show inventory" command would show the serial number.
The serial number is on a sticker on the outside of the switch chassis, or on a pull tab on the face of the switch.
Atfer Get-NetAdapterRDMA | FT Name,InterfaceDescription,Enabled -AutoSize command at PowerShell of Windows Server 2012/R2 we get a good standing of RDMA both server and client machine.
But after Get-SmbClientNetworkInterface |? {$_.linkspeed -eq 10000000000} | FT FriendlyName,RSSCapable,RDMACapable -AutoSize we can see RSSCapable TRUE, and RDMACapable FALSE.
What's wrong?
Dear Mellanox Gurus,
Would you please advice the pros/cons of Omni-Path vs. Mellanox + Ethernet vs. InfiniBand?
Thanks in advance + Happy Monday

Every document I find on QoS sidetracks me with apparent requirements of IB or RoCE instead of simply telling me the minimum I need to do beyond creating an Ethernet header containing layer 2 CoS bits in a VLAN tag and/or doing the equivalent in an IP header DSCP sextet. In addition, my first experiment in attempting to do so, without any preliminary switch configuration led to a tcpdump capture on the receiving host with more than 100 ms between frames sent with only a nominal 10-µsec usleep between them. The same code run without a SX6036 issued over 1000 frames in less time than the one in the lab took to complete 100 or fewer. I've found very little about using Ethernet alone and obtaining desired behavior. What documents have I missed?
Looks like this cannot be done at the moment. Compiling with OVS/DPDK has a shared library requirement which mlx4 cannot be compiled as.
Hi,
I've installed OVS with DPDK using ConnectX-3 successfully. we support shared library (but not shared combined). I must state that it was few months ago (DPDK 2.0) so i hope this is still the case. I'm currently re-visiting it again so hopefully will have exact instructions for you soon.
