Initial programming of SPI flash for WG82574

[AFrid]

Hello,

I am designing in WG82574 with NVidia Tegra K1. And I have few questions:

1) which NVM is better to use: SPI flash or EEPROM?

2) What means are there to initially program the blank device from item 1 soldered on the board?

Would appreciate any help on that.

Hello Anatoly_Fridman,

Thank you for contacting the Intel Embedded Community.

In order to determine the proper NVM to your design, the information stated in Table 25, on page 54 of the http://www.intel.com/content/dam/doc/datasheet/82574l-gbe-controller-datasheet.pdf Intel(R) 82574 GbE Controller Family Datasheet may help you to define the device that better fit to your needs.

Could you please paraphrase or explain in detailed way your second question?

Thanks in advance for your collaboration to answer your questions.

Best Regards,

Hi Carlos,

thanks for replying. I do have the data sheet and saw the tables. My first question is related to the second in a sense. I want to know how to initially program the NVM. If I can do it in ARM embedded system with one only, let say EEPROM, then I will use EEPORM. If I can do it with flash, then I will use flash. If I can do it with any, my next question will be if I use EEPROM do I still have to use flash? If the answer is yes, then I prefer flash since it is one chip vs. two.

My second question is about means to program in embedded ARM environment soldered down blank NVM chip (whatever is used EEPROM or flash). Is there a utility for ARM processor to program the NVM chip? What should be implemented in h/w in order to program the chip? I couldn't find this kind of information in the data sheet. The information is more for s/w, not for h/w implementation. So, if the NVM is blank, will the chip be enumerated on PCIE bus? And then by running the utility and specifying a configuration file will program the NVM?

Could you help me in understanding that?

Thanks,

Anatoly

Hi Gabriel Thomas,

We are using WG82574 Gigabit Ethernet Controller in our design with ARM processor.

We also have similar question about the initial programming of EEPROM/Flash.Could you help me in that.

Hi Carlos,

I've got some "picture" from the thread and have more questions:

1) the thread is about I210. We are going to use 82574. I am not sure how different those from s/w stand point are.

2) I understood that there is no s/w tool for ARM/Linux for programming flash NVM.

3) I understood that there is ARM/Linux tool to program EEPROM NVM.

Could you clarify the item # 1 and confirm/or clarify items 2 and 3?

Thanks,

Anatoly

Hello Carlos,

Thanks for your reply,

We are using EEPROM in our design.I have the below queries ,please clarify

1) Whether eepromARMTool can be used to do initial programming to blank external EEPROM in case of 82574? if yes please provide the eepromARMTool tool for ARM/Linux.

2) My understanding is the configuration file will be in .Hex file and eepromARMTool is required to program the .Hex file into Blank external EEPROM .Please let me know is this understanding is correct ? if yes where can i get the configuration .Hex file ?

Thanks and Regards,

Aadhil.
