1G operation of 82599

Jump to solution

We have a design using the 82599 that has errors such that we can only

use one lane is each direction. As we would like to test as much of the

design as possible before doing the revision, are there EEPROM files

available that allow 1G SERDES operation on lane 0 of the 82599? I couldn't

find any in Rev 4.25 version of 82599_EEPROM.zip

Thanks, Paul.

Dear Carlos,

Thank you for this information. I now get 1G linkup

shown at the switch connected to the 82599 and

at the 82599. However I cannot pass any data.

The switch statistics show data going to the 82599.

I can try "ping" to a device on the same network

as that set using "ifconfig". But I see no packets

counted for Tx or Rx for the 82599.

Another thing I have noticed is that the driver puts

out an "Adapter Removed" message when I set

the IP address using "ifconfig". As there is no

obvious way to attach a file to this message, I'll

include the driver output and lspci output below.

The lspci output is odd in that the BAR registers

show as "disabled", rather than having an address

set.

Thanks, Paul.

Hello paulwilcox-baker,

Thanks for your update.

In order to better understand this situation, we would like to address the following questions:

Could you please clarify us if the affected device is an Intel NIC or your own design?

In case that it is your project:

Could you please let us know the used NVM image?

Could you please confirm if this design has been reviewed?

Could you please inform us the type of connection that you are using (if it is Backplane or SFP/SFP+)?

Could you please give us all the information of the devices that you are connecting to the affected units?

In case that it is an external device, could please let us know if you have tried to connect it with a NIC?

Please give us all the information that should answer these questions to have better idea of your problem.

Thanks in advance for your cooperation.

Best Regards,

Carlos_A.

Dear Carlos,

I did get data transfer in the end.

The "Adapter removed" message

seems to be caused by a race

condition between the BIOS doing

PCIe setup and reset being removed

from the 82599. This caused the PCIe

BAR registers to be left at zero. After doing a reboot,

which doesn't issue a hardware reset

to the 82599, The BIOS loads the BAR

registers correctly and the driver loads properly,

and I can transfer data.

I thought I had marked your post about the

register settings as "Correct Answer"

Thanks for the help, Paul.
