bring up method of I350-AM2 ?

Jump to solution

Hello!

We are using I350-AM2 with Freescale i.MX6Q, and i have some questions.

1. Can i use I350-AM2 without EEPROM?

2. If i cannot use I350-AM2 without EEPROM, how can i write EEPROM after booting completed?

3. Is there any reference EEPROM data? Or can i dump EEPROM from NIC that used I350, then mod this dumped data, then apply to our board?

Thanks!

Hi Heeseob Jung

Referring to Section 3.3.1.4 Software Accesses:

"The I350 provides two different methods for software access to the EEPROM. It can either use the builtin controller to read the EEPROM or access the EEPROM directly using the EEPROM's 4-wire interface…

Software can also directly access the EEPROM's 4-wire interface through the EEPROM/Flash Control

(EEC) register. It can use this for reads, writes, or other EEPROM operations."

 

To directly access the EEPROM, software should follow these steps:

 

1. Take ownership of the EEPROM Semaphore bit as described in Section 4.7.1.

2. Write a 1b to the EEPROM Request bit (EEC.EE_REQ).

3. Poll the EEPROM Grant bit (EEC.EE_GNT) until it becomes 1b. It remains 0b as long as the

hardware is accessing the EEPROM.

4. Write or read the EEPROM using the direct access to the 4-wire interface as defined in the EEPROM/

Flash Control and Data (EEC) register. The exact protocol used depends on the EEPROM placed on

the board and can be found in the appropriate datasheet.

5. Write a 0b to the EEPROM Request bit (EEC.EE_REQ) to enable EEPROM access by other drivers.

 

We are going to upload the document # 474233 Intel® Ethernet Controller I350 [Powerville] – EEPROM Images – Rev. 1.63, and we will let you know as soon as the document is available.

Best Regards.

Josue.

Hi Heeseob Jung.

According to https://www-ssl.intel.com/content/www/us/en/ethernet-controllers/ethernet-controller-i350-datasheet.... Intel® Ethernet Controller I350 Datasheet there are some features that only can be configured from EEPROM, for example section 3.2.1.1 Channel Behavior:

"SMBus connection speed bits define the SMBus mode. Also, SMBus frequency support can be defined only from the EEPROM."

We still working in the others questions, we will let you know as soon as possible, please stay tuned.

Best Regards. Josue.

Hello,

we are using the I350 on our design. Is their a software(linux) where we are able to programm the eeprom images incircuit.

Hi!

Thanks for update. This is what need for us too.

But this package contains x86/amd64 binaries only...

I was making eeprom update program based on datasheet's description, but that was difficult and have no time to complete.

Could i get celo/eeupdate/lanconf/... binaries for arm architectures?

Sorry to ask this now.

Thanks. Have a nice day!

Hello Heeseob,

Currently, there is not a tool specifically for I350.

If you want to modify the eepromarmtool source code to add support for I350, you are free to do it, it is needed to add extra information such as the device id and verify that the pcie registers are correctly defined. However Intel has no validated this kind of modifications, so it should be validated by your own.

 

Best Regards.

Josue.
