eepromARMtool

MPatt3 — Tue, 03 Feb 2015 18:35:03 GMT

Where do I find the eepromARMtool code? I am working on an ARM based design that uses an i210. I would like to program the NVM via this tool so that I can get the driver to load.

Regards,

Matt

Hello pattiwack

I sent you the eepromARMTool to your e-mail.

You might want to check the following resources:

Thanks Adolfo,

We tried compiling and running the program but its failing with a bus error. See below:

Hello pattiwack

Sorry for the delay

Our Intel engineers suggest two possibilities:

1) A conflict because mixing endians, as suggested in the user's guide from the eepromARMtool:

Another thing to consider is that ARM systems can be Bi-Endian. Therefore, you should verify the Endianness being used, especially when programming values at the bit level.This document does not cover verifying Endianness. However, you should be aware that eepromARMtool reflects a Little Endian implementation to match the hardware datasheets.

2) There is a possibility that for certain hardware the Operating System locks the page after it was allocated.

Check the following thread that could be useful to you:/message/10363 I210 detection issues under embedded linux -- (i211)

Re: eepromARMtool

MPatt3 — Sun, 08 Feb 2015 22:26:00 GMT

So we preprogrammed one of the flash parts and then put it back on our board and then eepromARMtool would work. Shouldn't the tool be able to identify and program a blank flash attached to a i210?

Regardless, we still can't bring up the ethernet interface. We see the following error when we do:

[root@alarm ~]# ifconfig enp3s0 up

igb 0000:03:00.0: Error -22 getting interrupt

When we look at dmesg when linux is booting and loading the ethernet driver we see the following:

Hello Matt

Sorry for the delay

Could you please provide answers to these questions:

Did you program the eeprom separately before using the eepromARMtool?

Did you get the same errors before using the eepromARMtool?

Best Regards,

Adolfo

Re: eepromARMtool

MPatt3 — Fri, 13 Feb 2015 01:50:56 GMT

So when the flash parts were blank we could see the parts via lspci but their device id was 1531 (which I believe is correct for an unprogrammed i210). However the eepromARMtool would not run. We took the flash parts off the board and programmed them with a 3rd party programmed using one of intel's example binary images and then we saw the device id change to an i210 and the eepromARMtool then would work. We would prefer to use the eepromARMtool to program blank parts so we wouldn't have to remove them (or preprogram them).

Regardless of this, with the flash parts now programmed we can not bring up the ethernet interface. The driver complains with "Error -22 getting interrupt". As result we are currently blocked with getting this working. Any ideas with might be causing this or how to further debug this problem?

Regards,

Matt

MPatt3 — Mon, 16 Feb 2015 18:29:43 GMT

Adolfo,

Here is some more info on our problem.

Once the EEPROM is programmed and re-soldered to the board the igb driver loads and we are able to read and write to the EEPROM with eepromARMtool tool. But the driver doesn't configure correctly. The PCIe root complex supports MSI interrupts (not MSI-X), but the driver loaded using legacy interrupts:

[ 1.159680] pci 0000:00:00.0: enabling device (0144 -> 0147)

[ 1.164007] pci 0000:01:00.0: enabling device (0140 -> 0143)

[ 1.168325] pci 0000:02:02.0: enabling device (0140 -> 0143)

[ 1.172663] igb 0000:03:00.0: enabling device (0140 -> 0142)

[ 1.210435] igb 0000:03:00.0: added PHC on eth0

[ 1.213606] igb 0000:03:00.0: Intel(R) Gigabit Ethernet Network Connection

[ 1.219137] igb 0000:03:00.0: eth0: (PCIe:unknown:unknown) 00:a0:c9:00:00:00

[ 1.224967] igb 0000:03:00.0: eth0: PBA No: 000300-000

[ 1.228719] igb 0000:03:00.0: Using legacy interrupts. 1 rx queue(s), 1 tx queue(s)

[ 1.235130] pci 0000:02:03.0: enabling device (0140 -> 0143)

[ 1.239423] igb 0000:04:00.0: enabling device (0140 -> 0142)

[ 1.277118] igb 0000:04:00.0: added PHC on eth1

[ 1.280260] igb 0000:04:00.0: Intel(R) Gigabit Ethernet Network Connection

[ 1.285838] igb 0000:04:00.0: eth1: (PCIe:unknown:unknown) 00:a0:c9:00:aa:aa

[ 1.291626] igb 0000:04:00.0: eth1: PBA No: 000300-000

[ 1.295394] igb 0000:04:00.0: Using legacy interrupts. 1 rx queue(s), 1 tx queue(s)

Then when we try to connect the Ethernet port we get an error 22:

[root@alarm ~]# ifconfig enp4s0 up

igb 0000:04:00.0: Error -22 getting interrupt

SIOCSIFFLAGS: Invalid argument

Using modprobe with MSI option

[root@alarm ~]# modprobe igb IntMode=1

igb 0000:03:00.0: added PHC on eth3

One more piece of info. This morning we reproduced the problem on a development platform that did not have the PLX switch present. Just the i210 directly attached to the zynq part acting as the root complex. Same result.

Here's the latest from the engineer working on debugging the driver...

"I'm can build the IGB driver locally on the picoZed now (Linux alarm 3.17.0-xilinx # 1 SMP PREEMPT Mon Feb 16 20:34:22 PST 2015 armv7l GNU/Linux). Below is the driver and loading information from several visions. All are showing the same error -22 when connecting the network interface. With debug level set to 16, both the 5.2.9.4 and 5.2.15 drivers are showing: Failed to initialize MSI interrupts. Falling back to legacy interrupts.

Please pass along to intel

Van"

Hello pattiwack

Could you please tell me the name of the image that you are using to program this I210?

Also if you are using I210-IS/AS or I210-IT/AT?

Best Regards,

Adolfo

Re: eepromARMtool

MPatt3 — Wed, 18 Feb 2015 23:49:16 GMT

Hi Adolfo,

The image we used is Dev_Start_I210_Copper_NOMNG_8Mb_A2_3.25_0.03.bin

Once that was preprogrammed in the flash then the eepromARMtool would work so we could program the mac address. No other mod's were done.

I210IT is the part we are using.
