Hi Minho, It sounds like your NVM isn't correctly set up. I'm just the ixgbe driver owner so don't configure eeprom's myself, but I'll see what I can find out or find someone to point you at. When you purchased the x520 LOM (I'm assuming your developing a LOM system) weren't you provide a dev starter kit that contained a eeprom imagine?
It might be helpful if you could dump the eeprom and send it to me along with the output from 'ethtool -i ethX'. At least I can say that you do have the correct data sheet 82599 == X520. :) Thanks, -Don Skidmore <[email protected]> > -----Original Message----- > From: mhban [mailto:[email protected]] > Sent: Thursday, May 02, 2013 12:09 AM > To: Kirsher, Jeffrey T > Cc: [email protected]; Brandeburg, Jesse > Subject: [E1000-devel] Intel 10GbE NIC eeprom read error > > Dear maintainer, > > I'm developing device which is based on ARM processor and the processor > supports PCI Express root-port. > I'm trying to install Intel X520-SR2 adapter on this device(Linux) but there > is > problem when ixgbe driver probe device. > Here is brief system configuration. > > Processor : ARM SoC (Cortex-A15, ARMv7) > Adapter : Intel® ETHERNET SERVER ADAPTER X520-SR2 > (/w Intel DUAL RATE 1G/10G SFP+ SR : AFBR-703SDZ-IN2) > OS : Linux Kernel 3.9.0-rc4 > > I attached console log.
