IMX6Q pcie ethernet card

zhaosongluo · ‎12-29-2014

hi!

I am using INTEL pc82573E(pcie to 1000Gbit ethernet) on our custom IMX6Q board based on SabreSD board. but it seems that could not recognise the devcie properly.

the kernel is Linux 3.0.35-imx,and we choose board (mx6q_sabresd) on LTIB config.

here is what i have done:

add a star to:

System Type -> Freescale MXC Implementations -> PCI Express support

Bus support -> Message Signaled Interrupts (MSI and MSI-X)

Bus support -> PCI Express Support

Device Drivers -> Network Device support -> Ethernet (1000 Mbit)

Device Drivers -> Network Device support -> Ethernet (1000 Mbit) -> Realtek 8169 gigabit ethernet support

Device Drivers -> Network Device support -> Ethernet (1000 Mbit) -> Intel(R) PRO/1000 Gigabit Ethernet support

Device Drivers -> Network Device support -> Ethernet (1000 Mbit) -> Intel(R) PRO/1000 PCI-Express Gigabit Ethernet support

Device Drivers -> Network Device support -> Ethernet (1000 Mbit) -> IP1000 Gigabit Ethernet support

Device Drivers -> Network Device support -> Ethernet (1000 Mbit) -> Intel(R) 82575/82576 PCI-Express Gigabit Ethernet support

Device Drivers -> Network Device support -> Ethernet (1000 Mbit) -> Intel(R) 82576 Virtual Function Ethernet support

and remove the star from: make menuconfig -> Device Drivers -> Network Device support -> Ethernet (10 or 100Mb)

after compile the kernel i use MfgTool2 to load the uImage to the emmc on board.

After reset the board, here is the log about pcie on system boot:

-----------------------------------------------------

when i login into the system, i use the ifconfig command,but there is no eth device:

-------------------------

root@freescale ~$ ifconfig

root@freescale ~$

-------------------------

while when i use the lspci,here is the output:

---------------------------------------

root@freescale ~$ lspci

00:00.0 Class 0604: 16c3:abcd

root@freescale ~$ lspci -mk

00:00.0 "Class 0604" "16c3" "abcd" "0000" "0000" "pcieport"

---------------------------------------

i am a newer to pcie, so i have no idea to locate the problem !

Any advise would be greatful!

i test on my pc,the pcie to 1Gbit ethernet card works well.so the pcie card has no problem.

but now why the kernel could not recognise the INTEL 82573 CARD.

Hi zhaosong

it may be suggested to get updated intel driver for that chip or try

more new kernel, which has more devices supported

L3.10.17_1.0.0_IMX6QDLS_BUNDLE : Source Code Download Steps Documentation and Demo Images.

hi igor!

i could not found the imx-3.10.17-1.0.0-ga-mfg-tools.tar.gz on the internet.

would you please give me a link to that tools,so that i could try the yocto images!

thanks!

hi igor!

sorry for delay reply! my problem is still not resolved.

i have tried the ubuntu system,and could get more information through the lspci -v .

could see any thing is wrong on the information below

i will try other kernels later.

---------------------------------------------------------------------------------------------------

Hi Zhasong, in addition to Igor's suggestions, I just want to add that :

IMX PCIe port: link up

seems to indicate that PCIe is seeing your card properly but

later on when you issue lspci , it doesn't look like it is

listing your card :

root@freescale ~$ lspci

00:00.0 Class 0604: 16c3:abcd

I believe this is the pcie root. Do you ever get your ethernet card's id as

a result of lspci ?

Which kernel version are you using ? You can also try the mainline

kernel if you haven't yet.

Lastly, if this is your custom board, verify the power on

gpio is defined properly for the kernel. Are you able to

use any other pcie card successfully on your custom board ?

Hope this helps

Regards

hi Sinan Akman!

I have not get the ethernet card's id as a result of lspci. unfortunately,i have only this pcie card on my hand.

while the vesion of the kernel is

-------------------------------------------------------------------------

root@linaro-ubuntu-desktop:~# cat /proc/version

Linux version 3.0.35-2666-gbdde708 (root@imx) (gcc version 4.6.2 20110630 (prerelease) (Freescale MAD -- Linaro 2011.07 -- Built at 2011/08/10 09:20) ) #5 SMP PREEMPT Sun Jan 4 18:23:53 CST 2015

-------------------------------------------------------------------------

maybe this kernel is two old.

i will check the power on gpio for the kernel and try more kernel.

Thanks for your suggestion!
